[PROJECTOR RUNNING] PROFESSOR T.: FOR CENTURIES, SCIENTISTS HAVE CONJECTURED THAT CERTAIN PEOPLE ARE PREDISPOSED TO CRIMINAL BEHAVIOR.

IN 1876, CESARE LOMBROSO CLAIMED TO HAVE FOUND EVIDENCE THAT SOME PEOPLE WERE BORN OFFENDERS.

HE BELIEVED THE CRIMINAL GENE COULD BE PASSED ON AND THOSE THAT INHERITED IT WERE RECOGNIZABLE BY THEIR PHYSICAL CHARACTERISTICS.

ONE MIGHT WONDER IF LOMBROSO HAD BEEN DRINKING TOO MUCH LAMBRUSCO WHEN HE DEVELOPED HIS THEORY.

[STUDENT COUGHS] [INDISTINCT CHATTER] [CLASSICAL MUSIC PLAYING] PROFESSOR T.: BUT WHAT IF ONE MIGHT RECOGNIZE A CULPRIT BY THE HEAVINESS OF HIS BROW, HIS RECEDING HAIRLINE OR MAYBE JUST HIS UNFEASIBLY LARGE EARS?

IN TRUTH, CRIMINALITY IS MUCH HARDER TO DISCERN.

ANY ONE OF US COULD BE HARBORING MURDEROUS INTENT, NO MATTER HOW BENIGN OUR OUTWARD PROJECTION.

AS LONG AS I OUTRUN YOU, YOU BASTARD!

PROFESSOR T.: IT IS ONLY WHEN OUR NEIGHBOR TURNS OUT TO BE A SERIAL KILLER THAT WE REALIZE IT.

HELLO.

POISON MAY LURK IN THE MOST INNOCUOUS OF VESSELS.

[CLASSICAL MUSIC CONTINUES] [COUGHING] I... [SPUTTERS] [GAGGING] [GUESTS GASP] PROFESSOR T.: YOUR TASK THIS WEEK IS TO WRITE AN ESSAY ON THE NATURE OF A CRIMINAL.

[CLASSICAL MUSIC CONCLUDES] [THEME MUSIC PLAYS] DAN: UNEXPLAINED DEATH, 50-SOMETHING MALE, ALMOST INSTANT, APPARENTLY.

ANYTHING MORE?

CHIEF LIBRARIAN AT THE UNIVERSITY.

SAY HIS CHAPTER'S CLOSED.

HALF A DOZEN WITNESSES IN THE IMMEDIATE VICINITY.

WE'RE TAKING PRELIMINARY STATEMENTS.

THERE ARE MORE THAN A 100 NAMES ON THIS GUEST LIST.

WE NEED CONTACT DETAILS FOR ALL OF THEM.

WE'RE GOING AS QUICK AS WE CAN.

YOU CAN ADD ANOTHER 20 STAFF TO THAT NUMBER.

GOT THIS LIST FROM THE HEAD OF CATERING.

ANY CHANCE IT'S JUST A HEART ATTACK?

POISONING MORE LIKELY.

CARBON DIOXIDE IN THE CHAMPAGNE MAKES IT WORK MUCH FASTER.

CHEAP AND NASTY CAVA BY THE SMELL OF IT, BUT THE EFFECT IS THE SAME.

HE SHOULD HAVE STUCK TO BEER.

PAUL: THERE ARE TWO GLASSES.

MARTIN: WE'LL TEST BOTH.

THE WAITRESS WE SPOKE TO GOT THE GLASS FROM THE SERVICE TABLE.

DAN: IF IT IS POISON, ANYONE IN THE ROOM COULD HAVE PUT IT IN THE GLASS.

AND ANYONE COULD HAVE DRUNK IT.

IT'S GOING TO BE A LONG NIGHT.

MARTIN: DESPERATE DAN SEEMS DELIGHTED BY THE PROSPECT.

YOU'RE SUCH A BITCH, MARTIN.

YOU FANCY HIM?

OH, HE FANCIES YOU OBVIOUSLY.

OH, RIGHT.

I DON'T BLAME HIM.

[♪♪♪] [RATTLING] [MOTOR SPUTTERS OUT] [BANGING ON SIDE] [MOTOR GRINDS] [BANG BANG] [MAN SINGING IN ITALIAN] I'M GLAD YOU FINALLY NOTICED THE NOTICE BOARD.

IS THERE SOMETHING ON IT WORTH NOTICING?

IT'S A CLICHÉ, I KNOW, BUT BENEATH THIS LACQUERED VENEER... HMM.

MIGHT I INQUIRE, IN YOUR WILDEST DREAMS, WHAT DO YOU THINK THE LIFETIME OF A REFRIGERATOR MIGHT BE?

AN IQ OF A SQUILLION, BUT HE NEEDS HELP TO BUY A FRIDGE.

I MAY APPEAR TO BE AN ICE QUEEN, PROFESSOR, BUT THAT DOESN'T MAKE ME AN EXPERT IN WHITE GOODS.

BTW AND FYI, THERE ARE TWO VISITORS FROM HER MAJESTY'S CONSTABULARY IN YOUR OFFICE.

LEAVE IT, DAN.

[TAP] SNARES: I REALLY COULDN'T STOP THEM.

PROFESSOR T.: D.S.

DONCKERS, DETECTIVE, YOU'VE MADE YOURSELVES COMFORTABLE, I SEE.

WE'RE HERE ABOUT THE MURDER OF NIGEL WIGGINS.

DETECTIVE CHIEF INSPECTOR BRAND SUGGESTED THE TWO OF YOU WERE ACQUAINTED.

AH, YES.

MR. WIGGINS.

IF EVER THERE WAS A BOOK ONE COULD JUDGE BY ITS COVER.

THAT'S OUR PROBLEM.

NO WIFE, NO KIDS, NO FRIENDS, NO HOBBIES, DEFINITELY NO SCANDALS, JUST BOOKS.

DAN: WE BELIEVE THAT WHOEVER POISONED HIM MAY HAVE INTENDED ANOTHER TARGET.

A REASONABLE ASSUMPTION.

THANK YOU, MISS SNARES.

I'M SURE THE FENG SHUI IS FULLY RESTORED BY NOW.

THERE WERE A 115 GUESTS AND 20 STAFF.

WE'VE TAKEN PRELIMINARY STATEMENTS.

THE TROUBLE IS ANY OF THEM COULD HAVE PUT POISON IN THE GLASS, AND WE HAVE NO IDEA WHO THE INTENDED VICTIM WAS.

WE'RE LOOKING AT DAYS, MAYBE WEEKS OF INTERVIEWS.

IF THERE'S ANY PSYCHOLOGICAL INSIGHT THAT YOU CAN OFFER US, PROFESSOR, THAT MIGHT HELP US NARROW THE FIELD, WOULD BE-- YOU APPEAR TO HAVE RETAINED A MEAGER PORTION OF WHAT YOU WERE TAUGHT AT THIS ESTABLISHMENT, DETECTIVE SERGEANT.

LET ME REFRESH YOUR MEMORY.

POISON IS INFREQUENTLY USED TO COMMIT MURDER.

IT'S THE CAUSE OF DEATH IN JUST UNDER ONE HALF OF 1% OF ALL HOMICIDES.

PERHAPS MORE PERTINENT TO YOUR INQUIRY, WOMEN ARE SEVEN TIMES MORE LIKELY THAN MEN TO SELECT IT AS THE MEANS TO AFFECT A FATALITY.

I HOPE THAT'S OF SOME USE.

THAT COULD CERTAINLY HELP REDUCE OUR LIST A LITTLE.

AH.

MRS. CLAUDINE FROGGATT.

YOU KNOW HER?

SHE WORKS AT THE UNIVERSITY, ONE OF MANY SUPERFLUOUS JOBSWORTHS IN THE PROPERTY AND ACCOMMODATION OFFICE.

BUT NOT, IN YOUR OPINION, THE TYPE TO COMMIT A MURDER?

ARE YOU OF THE OPINION THERE'S SUCH A THING AS A MURDEROUS TYPE?

NO.

I JUST WONDERED IF YOU THOUGHT SHE MIGHT BE CAPABLE.

WHO KNOWS WHAT ANY OF US ARE CAPABLE OF IN EXTREMIS?

MISS SNARES... WOULD YOU KINDLY SHOW THE DETECTIVES OUT?

OF COURSE, PROFESSOR.

AS YOU KNOW, I'M NOT ONE TO TRADE IN TITTLE TATTLE, BUT THE WORD AT THE DEPARTMENTAL PERSONAL ASSISTANTS' LUNCH CLUB ON THURSDAY WAS THAT MRS. FROGGATT HAS CAUSE FOR A CERTAIN AMOUNT OF RIGHTEOUS INDIGNATION.

WITH MR. WIGGINS THE LIBRARIAN?

GOODNESS, NO.

WITH HER HUSBAND, THE RATHER FEMALE FRIENDLY MR. FROGGATT.

PROFESSOR T.: I SEE.

HELL HATH NO FURY.

WIGGINS: AHEM.

THIS ONE IS LONG OVERDUE, YOU KNOW?

PAUL: TOXICOLOGY HAVE CONFIRMED ITS CYANIDE.

THERE WAS A TRACE IN ONLY ONE OF THE GLASSES.

THERE'S EVERY CHANCE WIGGINS WASN'T THE INTENDED TARGET, THOUGH.

WE'RE WORKING THROUGH A LIST OF ATTENDEES.

THERE'S NOTHING FOR IT BUT LEG WORK.

I'VE ASKED LISA AND DAN TO SEE IF PROFESSOR TEMPEST MIGHT BE ABLE TO NARROW THE FIELD.

SUCH A GREAT HELP TO US ON THE RAPE CASE.

I THINK IT MIGHT EVEN BE AN IDEA TO PUT HIM ON A RETAINER.

SOMETHING TO THINK ABOUT MAYBE.

[FOOTSTEPS RECEDE] [POLICE SIREN IN DISTANCE] [♪♪♪] [DRINK POURING] MRS. FROGGATT.

OH, PROFESSOR TEMPEST.

MAY I OFFER MY COMMISERATIONS.

OH, THAT'S TERRIBLY KIND OF YOU.

YES, WHAT AN AWFUL SHOCK.

POOR MR. WIGGINS.

I WAS REFERRING TO YOUR HUSBAND AND THE REPORTS THAT HAVE REACHED ME OF HIS INFIDELITY.

I BEG YOUR PARDON?

["CAN-CAN" PLAYING] UH, PERHAPS I WAS BEING A LITTLE INDELICATE.

PERHAPS.

[MUSIC CONTINUES] MY APOLOGIES.

I WAS UNDER THE IMPRESSION IT WAS THE TALK OF THE CORRIDORS.

IT IS?

[MUSIC CONTINUES] IF IT HAS REACHED ME, THEN APPARENTLY SO.

WELL, I DON'T KNOW WHAT BUSINESS IT IS OF YOURS OR ANYONE ELSE'S FOR THAT MATTER.

WHEN THE OFFICERS BRING YOU IN FOR QUESTIONING, MAY I RECOMMEND YOU DO NOT CONCEAL THE UNFORTUNATE MATTER OF YOUR HUSBAND - AND HIS DALLIANCE.

- BRING ME IN?

I IMAGINE THEY WILL PREDOMINANTLY BE LOOKING AT FEMALE SUSPECTS WHO MAY HAVE HAD A MOTIVATE TO WISH HARM ON SOMEONE ATTENDING THE EVENT.

THANK YOU.

[♪♪♪] [MAN SINGING IN ITALIAN] [KNOCK ON DOOR, DOG BARKS] [MUSIC CONTINUES FROM OTHER ROOM] JASPER, DARLING.

DON'T CROUCH THERE LIKE A COSSACK.

IT'S BAD FOR YOUR POSTURE.

WHAT ARE YOU DOING HERE, MOTHER?

WHAT?

WHAT ARE YOU DOING HERE?

I'M VISITING THE STUDIO.

NOW THAT YOU'VE DECIDED TO MOVE BACK IN, I THOUGHT I MIGHT ALSO TAKE UP RESIDENCE ONCE AGAIN.

HMM.

AND WHAT DO YOU WANT WITH ME?

SORRY?

AND WHAT DO YOU WANT WITH ME?

I MERELY WISH TO ASK WHEN WE CAN EXPECT THIS CHARADE TO BE OVER.

HOW LONG DO YOU PLAN TO HOLE YOURSELF UP IN THIS CATACOMB?

INDEFINITELY!

DON'T BE RIDICULOUS, JASPER!

THIS PLACE IS NOT GOOD FOR YOU.

NOT GOOD!

"SHARPER THAN A SERPENT'S TOOTH IS TO HAVE A THANKLESS CHILD."

"KING LEAR."

[DOG BARKS] WHAT'S THE HURRY?

MRS. FROGGATT'S HERE -- VOLUNTARILY.

- HERE YOU GO, MRS. FROGGATT.

- OH, THANK YOU.

THIS MY COLLEAGUE D.S.

DONCKERS.

- LISA: HI.

- HELLO.

YOU WERE TELLING ME YOUR HUSBAND WORKS LONG HOURS.

YES, HE'S CHIEF PLANNING OFFICER FOR THE COUNCIL AND ACTING TREASURER FOR THE MUSEUM'S BOARD OF TRUSTEES.

- BUSY MAN.

- YES.

HE ALWAYS HAS BEEN...

BUT RECENTLY IT--IT'S NON-STOP.

HE'S--HE'S AWAY EVENINGS, WEEKENDS...

I'VE BARELY SEEN HIM.

AND THAT MADE YOU SUSPICIOUS?

[SIGHS] I--I FOUND A CREDIT CARD RECEIPT FOR A HOTEL ROOM.

STANSTED MOUNTFITCHET OF ALL PLACES.

HE JUST LEFT IT IN HIS POCKET LIKE HE DIDN'T EVEN CARE IF HE WERE TO GET CAUGHT.

[SOBS] THANK YOU.

BUT THERE'S SOMETHING ELSE.

FAR WORSE THAN THE CREDIT CARD RECEIPT.

[KNOCK ON DOOR] DAN: GOOD AFTERNOON, MR. FROGGATT.

PLEASE TAKE A SEAT.

WE'RE LOOKING AT THE POSSIBILITY THE GLASS OF POISONED FIZZ AT THE RECEPTION WAS MEANT FOR YOU.

WHATEVER GIVES YOU THAT IDEA?

WE RECEIVED INFORMATION ABOUT A MAN WHO CAME TO YOUR HOUSE A WHILE AGO AND MADE THREATS TO YOUR SAFETY.

WHO TOLD YOU THAT?

YOUR WIFE.

MY WIFE?

SHE CAME TO THE STATION TO TELL US IN PERSON.

SHE ALSO TOLD US YOU'RE HAVING AN EXTRA-MARITAL AFFAIR.

IRATE HUSBAND PERHAPS?

[POLICE SIREN WAILS IN DISTANCE] [SOMBER MUSIC] HEY, HEY.

GIVE IT A CHANCE, LOVE.

YOUR HEARD WHAT HE SAID.

THEY'RE DISCOVERING NEW TREATMENTS ALL THE TIME.

[CELL PHONE CHIMES] SWEETHEART, I'M SO SORRY.

I'VE GOT TO GO.

BE BACK LATER, I PROMISE.

[SOMBER MUSIC CONTINUES] [KNOCK ON DOOR] CAN I COME IN?

PLEASE.

SO FROGGATT CLAIMS HE CAN'T REMEMBER ANY SPECIFIC THREAT.

ACCORDING TO HIM, YOU PISS OFF A LOT OF PEOPLE WHEN WORKING IN PLANNING FOR THE COUNCIL, BUT I DON'T UNDERSTAND MRS. FROGGATT VOLUNTEERING SO MUCH INFORMATION ABOUT HER HUSBAND.

I MAY HAVE PLAYED A PART IN THAT.

IN WHAT WAY?

I MERELY SUGGESTED SHE UNBURDEN HERSELF TO YOU.

SO YOU THINK SHE ATTEMPTED TO MURDER HER HUSBAND THEN?

HOW RIDICULOUS.

MRS. FROGGATT IS OBVIOUSLY INNOCENT.

THEN WHY HAVE ME WASTE MY TIME INTERVIEWING HER TODAY?

WHO SAYS YOU WASTED YOUR TIME?

[WOMAN SINGING IN ITALIAN] [DEEP SIGH] [MUSIC CONTINUES] [FOOTSTEPS RECEDE] FUNNY PLACE TO MEET.

UGH!

[SINGING ENDS] [THUD] - [BELL TOLLS] - [BIRDS CHIRPING] LISA: MY DOCTOR'S PRESCRIPTIONS ARE EASIER TO DECODE THAN THIS.

I DON'T HAVE BAD HANDWRITING.

I'VE JUST GOT MY OWN FONT.

PAUL: MORNING.

HAVE WE IDed HIM?

JONATHAN FELL.

YES, HE DID.

THE PHONE WAS BY HIS SIDE, KEYS WERE IN HIS POCKET, DRIVING LICENSE AND WALLET WERE IN THE CAR AND THIS.

UNIFORM HAVE BEEN TO THE HOUSE.

NOBODY'S IN, BUT THE NEIGHBORS SAY THEY SPEND A LOT OF TIME AT THE HOSPITAL.

THEIR DAUGHTER IS BEING TREATED FOR LEUKEMIA.

PAUL: POOR SOD.

ANYTHING TO SUGGEST IT'S NOT SUICIDE?

HE WAS STILL WEARING HIS GLASSES.

AND THAT'S WHAT THAT GOT TO DO WITH THE PRICE OF TEA IN CHINA?

MAYBE NOTHING.

IT'S JUST...

IT'S JUST WHAT?

IT'S JUST THIS STAT I REMEMBER FROM ONE OF MY CRIMINOLOGY LECTURES.

MORE THAN 90% OF VICTIMS REMOVE THEIR SPECTACLES BEFORE KILLING THEMSELVES.

HERE WE GO AGAIN.

MARTIN: HEY, GUYS.

LOOK AT THIS.

THERE MIGHT BE SOMETHING ON THE EDGE OVER THERE, MAYBE A HEEL MARK.

IT'S NOT EXACTLY DISTINCTIVE.

LET'S MAKE SURE WE LIFT A PROPER PRINT OFF OF IT.

PAUL: AT LEAST THAT'S SOMETHING CONCRETE FOR US TO WORK WITH.

NO PUN INTENDED.

AND NOT SOME CRACKPOT STATISTIC FROM THE INSUFFERABLE PROFESSOR KNOW-IT-ALL.

[♪♪♪] [BIRDS CHIRPING] WHAT'S THE OCCASION?

IT'S MY BIRTHDAY.

OH, I WISH I'D KNOWN.

I WOULD HAVE GOT YOU SOMETHING.

IS HE IN?

[KNOCK ON DOOR] RIGHT.

DIG OUT THE DEPARTMENTAL CREDIT CARD... AND GET ONTO LASTMINUTE.COM.

[MAN SINGING IN ITALIAN] DID YOU KNOW YOU CAN BUY CYANIDE ON THE DARK WEB?

£15 STERLING FOR 50 GRAMS.

THAT SEEMS SURPRISINGLY CHEAP.

YOU NEED APPROXIMATELY 0.15 GRAMS TO KILL AN ADULT, SO 333 CORPSES, GIVE OR TAKE, FOR A MERE 15 QUID.

YOU'RE A TRUSTEE OF THE MUSEUM, AREN'T YOU?

NOT FOR SEVERAL YEARS NOW.

WERE YOU EVER ACQUAINTED WITH THE TREASURER, A MR. ROLAND FROGGATT?

A PREENING POPINJAY.

BUT A GENEROUS DONOR TO FUNDRAISING APPEALS ON THE MUSEUM'S BEHALF.

HMM.

WELL, HE BOUGHT HIS WAY TO WHATEVER STATUS HE CURRENTLY ENJOYS.

I'VE BEEN LOOKING INTO THE LIBRARY'S AFFAIRS.

IT WOULD APPEAR THAT A MEMBER OF THE FACULTY HAS RETURNED A LARGE NUMBER OF PERIODICALS IN THE LAST 24 HOURS.

INTERESTING.

[RECORD SKIPPING] SOME OF WHICH WOULD HAVE BEEN RETURNED MORE THAN A DECADE AGO.

GIVEN THE SAD DEMISE OF MR. WIGGINS, WHICH ONE ASSUMES IN NO WAY MOTIVATED THE RETURN, I'M PROPOSING A MORATORIUM ON OUTSTANDING FINES.

[SKIPPING STOPS] GENEROUS.

HMM.

AND IN RETURN FOR THAT GENEROSITY, I WONDER IF ON BEHALF OF YOUR MOTHER I MIGHT SPEAK TO YOU ABOUT YOUR RETURN TO THE FAMILY HOME.

NO, YOU ABSOLUTELY MAY NOT.

WELL, THAT'S ALL SORTED THEN.

[MUSIC CONTINUES] WE'RE TRYING TO UNDERSTAND HOW YOUR HUSBAND DIED, MRS. FELL.

[CRYING] WE HAVE TO LOOK AT ALL POSSIBILITIES.

WERE YOU WORRIED AT ALL ABOUT HIS MENTAL STATE THE LAST TIME YOU SPOKE TO HIM?

[CRYING CONTINUES] WOULD YOU PREFER IT IF WE SAVED THE QUESTIONS FOR LATER?

[SOBBING] [CELL PHONE VIBRATES] [INTRIGUING MUSIC] YES.

YOUR LARGEST BOUQUET OF ROSES, PLEASE.

RED.

MESSAGE.

YES.

THE MESSAGE SHOULD READ, "SORRY."

I'M SURPRISED YOU CAME.

HOW'S DESMOND?

DERRICK IS FINE, THANK YOU.

HOW'S YOUR MOTHER?

GOOD.

I GATHER YOU HAVE A PROPOSITION.

I DO.

HOW WOULD YOU FEEL ABOUT JOINING THE TEAM AS AN ADVISOR ON AN AD HOC BASIS?

WE HAVE SOME GREAT TALENT HERE.

LISA HAS AMAZING POTENTIAL.

DAN IS VERY SOLID, AND PAUL IS EXTREMELY CAPABLE.

- HE'S JUST... - NOT MUCH COP.

I WAS GOING TO SAY HE'S DEALING WITH SOME PERSONAL ISSUES.

SO I UNDERSTAND.

THE FACT IS WE'RE VERY STRETCHED HERE AT THE MOMENT DEALING WITH THE POISONING, AND THERE ARE QUESTIONS NOW BEING RAISED ABOUT THE SUICIDE.

UH... WE COULD REALLY DO WITH YOUR HELP.

I'LL CERTAINLY GIVE IT SOME THOUGHT.

GREAT, WONDERFUL NEWS.

WOULD YOU MIND SITTING IN ON AN INTERVIEW WITH ME NOW?

IT'S SOMETHING I'D LIKE TO SPARE PAUL.

HMM.

JOHN WAS AN OPTIMIST.

I NEVER COULD UNDERSTAND HOW HE REMAINED SO POSITIVE.

POSITIVE, OPTIMISTIC PEOPLE DO NOT GENERALLY COMMIT SUICIDE, MRS. FELL.

I SUPPOSE NOT.

WHICH SUGGESTS THERE MAY BE AN ALTERNATIVE EXPLANATION FOR HIS UNTIMELY DEMISE.

MURDER?

AN ACCIDENT, MORE LIKELY, BUT SINCE YOU MENTION IT, DID YOU KNOW THAT FOUR OUT OF FIVE MURDERERS ARE KNOWN TO THEIR VICTIMS?

IN 72% OF CASES, IT'S THEIR LONG-TERM PARTNER.

- ARE YOU SUGGESTING THAT-- - NO, NO OF COURSE NOT.

I'M SUGGESTING THERE'S A HIGH PROBABILITY THAT YOU KNOW WHOEVER KILLED YOUR HUSBAND, MRS. FELL, IF HE WAS MURDERED.

MRS. FELL: JONATHAN GOT ON WITH EVERYONE.

YOUR DAUGHTER'S VERY ILL.

HER CHANCES OF RECOVERY ARE SLIM.

- JASPER.

I'M SO SORRY.

- IT WOULD MAKE ANYONE ANGRY.

SHE WON'T DIE.

SHE CAN'T DIE.

- YOUR HUSBAND WAS ANGRY, TOO.

- JASPER.

HE HAD EVERY RIGHT TO BE.

♪ PAUL, MUFFLED: WE DON'T NEED HIS HELP.

[CHRISTINA MUFFLED] WE'RE MANAGING PERFECTLY WELL WITHOUT HIM.

I UNDERSTAND WHAT YOU'RE SAYING...

BUT IT'S JUST AS AN ADVISOR.

I'M NOT INTERESTED IN UNDERMINING YOU.

DON'T HIDE BEHIND THE JOB AS AN EXCUSE.

WE DON'T NEED HIS HELP.

HE HAS AN ABSOLUTELY FORENSIC BRAIN.

I THINK WE CAN ALL LEARN FROM HIM.

WE'RE WORKING PERFECTLY WELL WITHOUT HIM.

LOOK.

IT'S NOT A REFLECTION ON YOU.

NO.

IT'S A REFLECTION ON YOU.

APOLOGIES ACCEPTED.

ENJOY YOUR IRISH COFFEE.

I BEG YOUR PARDON?

WHAT DID YOU SAY?

WHAT DID YOU SAY?

IT'S A SCREW TOP.

YOU BUY SCREW TOPS BECAUSE MUMMY HIDES THE CORKSCREWS.

- MIND YOUR OWN... - BUSINESS.

CHRISTINA: CAN I GRAB YOU FOR A DEBRIEF, BOTH OF YOU?

THE FELLS MADE A COMPLAINT TO THE COUNCIL BECAUSE THEY BELIEVED FIELD ROSE HOMES KNEW THE SITE WAS CONTAMINATED BEFORE BUILDING ON IT.

SO WHAT DID THE COUNCIL DO?

NOTHING.

PERMITS AND PAPERWORK ALL SUPPOSEDLY HELD UP.

THE FELLS HAVE BEEN PREPARING LEGAL ACTION EVER SINCE, MR. FELL WORKING TWO JOBS TO COVER THEIR LEGAL COSTS.

DAN: MAYBE FIELD ROSE HOMES WERE WORRIED THE FELLS WERE ON TO SOMETHING, WORRIED ENOUGH TO PUSH HIM OFF A BUILDING.

CHRISTINA: MM-HMM.

SEEMS UNLIKELY THEY WOULD STAGE IT AT ONE OF THEIR OWN DEVELOPMENTS.

WHAT'S THE LATEST ON THE POISONING?

BACK AT SQUARE ONE.

WE'VE GOT NOTHING ON EITHER FROGGATT.

NO.

HANG ON.

FROGGATT WORKS AT THE COUNCIL IN THE PLANNING DEPARTMENT.

PRECISELY SO.

MR. FROGGATT IS RESPONSIBLE FOR TESTING ALL BUILDING SITES FOR CONTAMINATION BEFORE PLANNING PERMISSION CAN BE GRANTED.

WHEN MR. FELL DISCOVERED HIS OWN HOUSE WAS BUILT ON TOXIC LAND, HE CONFRONTED MR. FROGGATT AT HIS HOME AND THREATENED HIM.

LISA: AND SHORTLY AFTERWARDS SOMEONE ATTEMPTED TO MURDER FROGGATT AT THE MUSEUM.

I DO NOT BELIEVE IN COINCIDENCE.

PAUL: THERE'S NOT A SHRED OF PHYSICAL EVIDENCE TO CONNECT THESE TWO CASES.

DAN: WE'VE GOT THIS FOOTPRINT.

LISA: AND MR. FELL'S BELONGINGS ARE BEING EXAMINED FOR FORENSICS.

WE SHOULD HAVE THE RESULTS SOON.

CHRISTINA: ALL RIGHT.

DONCKERS, WINTERS, DIG INTO THE FROGGATTS AGAIN.

PROFESSOR T.: D.S.

DONCKERS...

THIS MAY PROVE USEFUL THE NEXT TIME YOU SPEAK TO MR. FROGGATT.

IT'S A LONG LIST OF NUMBERS.

IT'S A LONG LIST OF DONATIONS, DETECTIVE, MADE ON A COUNCIL WORKER'S SALARY.

[♪♪♪] MRS. FROGGATT.

SORRY.

DO YOU RECOGNIZE THIS MAN?

YES.

THAT'S THE MAN WHO THREATENED ROLAND.

THANK YOU.

[♪♪♪] LISA: HEY, MARTIN.

WHAT'S UP?

MARTIN: WELL, WE JUST FOUND FINGERPRINTS FROM A THIRD PARTY ON MR. FELL'S PHONE.

GUESS WHO THEY BELONG TO.

[♪♪♪] THIS REPORT, SIGNED BY YOU, FINDS NO EVIDENCE OF CONTAMINATION ON A SITE WHERE FIELD ROSE HOMES WENT ON TO BUILD 120 HOMES.

YEAH, THAT WOULD SEEM TO BE THE CASE.

DID THEY BRIBE YOU TO SAY THAT, MR. FROGGATT?

I DON'T KNOW WHAT YOU'RE TALKING ABOUT.

DO YOU KNOW A MR. JONATHAN FELL?

CAN'T SAY I DO.

YOUR WIFE HAS IDENTIFIED MR. FELL AS THE MAN WHO THREATENED YOU AT HOME.

LIKE I SAID, GET A LOT OF COMPLAINTS.

HE AND HIS WIFE BOUGHT ONE OF THE NEW HOMES ON THAT SITE.

THEY HAD THE SOIL TESTED INDEPENDENTLY.

LET ME READ IT TO YOU.

"THERE IS SIGNIFICANT INDICATION "OF A GINORMOUS LOAD OF POISONOUS CRAP ALL OVER THIS HELL HOLE."

HEHE!

IT DOESN'T SAY THAT.

BUT THAT WHAT IT BOILS DOWN TO.

YOU KNOW PERFECTLY WELL IT USED TO HOUSE A ZINC FACTORY.

THE FELLS' DAUGHTER IS BEING TREATED FOR LEUKEMIA.

CHANCES ARE HER ILLNESS IS CONNECTED TO THE POLLUTION.

WE FOUND EVIDENCE ON MR. FELL'S LAPTOP.

HE PURCHASED 50 GRAMS OF CYANIDE THROUGH AN ILLEGAL WEBSITE, THE SAME POISON THAT KILLED NIGEL WIGGINS AT THE RECEPTION.

- DID YOU RETURN THE FAVOR?

- DON'T BE RIDICULOUS.

YOU WEREN'T PRESENT WHEN MR. FELL DIED?

COULD BE ANYBODY'S FOOTPRINT.

LOOK AGAIN AROUND THE EDGES.

YOU DON'T TEND TO FIND EXQUISITELY HAND-STITCHED LOAFERS ON BUILDING SITES.

YOU CAN COME IN NOW.

DOESN'T PROVE ANYTHING.

BUT IT'S ENOUGH TO GET US A COURT ORDER TO FIND OUT WHERE THE MONEY CAME FROM TO FUND YOUR PASSION FOR FANCY ITALIAN FOOTWEAR AND FOR MAKING DONATIONS TO THE MUSEUM WITH YOUR SWANKY CHUMS.

YOU REALIZED WIGGINS WASN'T THE INTENDED VICTIM, DIDN'T YOU?

DAN: COULD YOU TAKE YOUR SHOES OFF PLEASE, SIR?

NO.

WHEN YOU LEARNED YOU MIGHT HAVE BEEN THE INTENDED TARGET, YOU GUESSED WHO'D DONE IT.

MAN: YOUR SHOE PLEASE, SIR.

DAN: WAS IT YOUR IDEA TO MEET AT THE BUILDING SITE?

FUNNY PLACE TO MEET.

LISA: TOOK A BIT OF A RISK, DIDN'T YOU, MEETING UP WITH A MAN WHO JUST ATTEMPTED TO MURDER YOU?

IT'S GOING TO BE QUITE SOMETHING, DON'T YOU THINK?

DAN: PERHAPS YOU FIGURED HE WOULDN'T HAVE THE NERVE TO TRY ANYTHING FACE TO FACE.

SOMEONE LIKE ME COULD NEVER AFFORD TO LIVE SOMEWHERE LIKE THIS.

OH, BUT YOU COULD.

LISA: DID YOU TEMPT HIM UP THERE WITH A PROPOSITION, MR. FROGGATT?

ROLAND: JUST DROP THE CASE, AND I'LL SIGN OVER THE DEEDS.

YOU CAN SHOVE YOUR BLOOD MONEY.

IT'S NOT FOR YOU.

IT'S FOR HER IN A FEW YEARS WHEN SHE'S RECOVERED.

FORGET IT.

EVERYTHING YOU JUST SAID...

RECORDED.

I THINK YOU LASHED OUT IN A PANIC.

GIVE ME THE PHONE.

UGH!

[THUD] [FAST-PACED MUSIC] [DOG BARKING] LISA: SO MUCH OF A PANIC, IN FACT, AFTER YOU ERASED EVERYTHING, YOU FORGOT TO WIPE YOUR FINGERPRINTS OFF MR. FELL'S PHONE.

[♪♪♪] IT WAS AN ACCIDENT.

I THOUGHT EVERYONE WOULD ASSUME HE COMMITTED SUICIDE... BECAUSE OF HIS DAUGHTER.

[♪♪♪] RIGHT.

LET'S GET PISSED.

WHAT'S UP?

DOESN'T IT BOTHER YOU THAT WE'VE GOT NO EYEWITNESS ACCOUNTS OF MR. FELL - AT THE MUSEUM THAT NIGHT?

- SO?

THERE WERE 130 PEOPLE PRESENT, AND NO ONE SAW HIM, AND THAT THING THE PROFESSOR SAID ABOUT POISON BEING AN INFREQUENT MEANS OF MURDER.

THERE'S SOMETHING VENGEFUL ABOUT IT.

EXACTLY, BUT EVERYONE SAID HE WAS SUCH A DECENT PERSON--MR. FELL.

WHAT WERE WE SAYING ABOUT THE PUB?

IT'S A BIT EARLY, ISN'T IT?

[SOFT MUSIC] [DRAMATIC MUSIC] YOUNG ADELAIDE: JASPER!

[MAN SINGING IN ITALIAN] [SHOUTING ANGRILY] WHAT DID YOU SAY?

[SLOWED DOWN] WHAT DID YOU SAY?

[MUSIC DISTORTING] [MUSIC CONCLUDES] [INDISTINCT CHATTER] THAT'S TO KILLING TWO BIRDS WITH ONE STONE.

I PROMISE, I WON'T TAKE ADVANTAGE OF YOU IF YOU GET FACED AGAIN.

NOT EVERYTHING IS ABOUT YOU, DAN.

WOW.

I'M GLAD YOU DECIDED TO COME TO THE PUB.

[CELL PHONE RINGING] SORRY.

I'VE GOT TO TAKE THIS.

DON'T MIND ME.

HELLO.

NO I'M IN A PUB.

ARE YOU ALL RIGHT?

ALL FINISHED, LOVE?

NO, OUR DINNER DATE IS TOMORROW.

ARE YOU SURE YOU'RE OK?

OF COURSE, DARLING.

IT'S JUST...

I THOUGHT I COULD SMELL SOME GAS IN HERE, SO I'VE OPENED SOME OF THE WINDOWS JUST IN CASE.

ALL RIGHT.

OK. ALL RIGHT.

HANG ON.

I'LL BE RIGHT THERE.

SORRY.

I HAVE TO GO.

GOT COMPETITION, HAVE I?

YOU HAVE TO BE A CONTENDER FOR THERE TO BE COMPETITION, DAN.

125, 130.

WOMAN: THANK YOU.

I'LL BE IN A BIT LATE TOMORROW.

[BIRDS CHIRPING] LISA: MR. TUCKER?

D.S.

DONCKERS.

YEAH, I REMEMBER.

I'M AFRAID I'M PRETTY BUSY.

TWO MINUTES, THAT'S ALL.

UNLESS YOU'D RATHER I GOT ON THE PHONE TO HER MAJESTY'S REVENUE AND CUSTOMS.

OK, OK. TWO MINUTES.

[PEPPY MUSIC] [MAN SINGING IN ITALIAN] [MUSIC DISTORTING] [SLOWED DOWN] HA HA HA!

[DISTORTED MUSIC CONTINUES] WOMAN: SIR?

EXCUSE ME.

IS EVERYTHING OK?

- CAN I HELP YOU?

- I'M LOOKING FOR LINA FELL.

ARE YOU A RELATIVE?

FAMILY FRIEND.

ROOM 116.

WHICH WAY IS THAT?

JUST FOLLOW THE YELLOW DOTS.

MRS. FELL?

I'D LIKE TO BE LEFT ALONE IF YOU DON'T MIND.

I WILL NOT STAY LONG.

MY FATHER DIED WHEN I WAS SEVEN.

I WAS RAISED BY MY MOTHER.

IF LINA PULLS THROUGH, SHE'LL NEED HER MOTHER, TOO... A MOTHER WHO IS NOT BURDENED BY HER CONSCIENCE.

WHY SHOULD I BE WORRIED ABOUT MY CONSCIENCE?

BECAUSE OUR CONSCIENCE IS OUR FOUNDATION.

ONCE CONTAMINATED, IT CAN DESTROY EVERYTHING.

[PENSIVE MUSIC] COME WITH ME.

DAN: "COME WITH ME"?

I'M NOT YOUR DOG.

PAUL: LISTEN.

I'LL CALL YOU BACK, YEAH.

CHEERS.

JONATHAN FELL DIDN'T KILL NIGEL WIGGINS.

IT'S BEEN BOTHERING ME.

HE WASN'T ON THE GUEST LIST, AND HE WASN'T ON THE LIST OF STAFF SUPPLIED BY THE CATERING COMPANY.

- SO HE SLIPPED IN UNNOTICED?

- AND LEFT BEFORE WE ARRIVED.

I'VE BEEN HAVING ANOTHER FRIENDLY CHAT WITH THE CATERING MANAGER.

TURNS OUT THERE ARE ANOTHER THREE PEOPLE IN ATTENDANCE WE HAVEN'T ACCOUNTED FOR.

THEY WERE OFF THE BOOKS, CASH IN HAND, ALL WOMEN.

I WAS ABLE TO GET THE FULL LIST.

TWENTY-THREE STAFF ALL IN THE BUILDING AT THE TIME OF THE MURDER, AND LOOK WHO'S ON IT.

[♪♪♪] YOU CAN'T IMAGINE HOW IT FEELS.

I SHOULD HAVE PROTECTED HER.

HOW CAN YOU PROTECT YOUR CHILD AGAINST SOMETHING YOU CAN'T EVEN SEE?

SO THE TWO OF YOU DECIDED TO KILL FROGGATT?

NOT JONATHAN.

[SNIFFLES] HE WAS FURIOUS, HEARTBROKEN...

BUT STILL HOPEFUL.

I WAS RESEARCHING ALTERNATIVE THERAPIES FOR LINA.

A LOT OF VERY DESPERATE PEOPLE SWEAR BY THE USE OF VITAMIN B17.

IT'S A NATURAL FORM OF CYANIDE, AND THEN ONCE YOU START LOOKING, WELL, YOU CAN BUY PRETTY MUCH ANYTHING ON THE INTERNET.

AND WHEN THE PACKAGE ARRIVED, IT WAS SIMPLY A CASE OF DELIVERING IT.

[INDISTINCT CHATTER] I'VE BEEN DOING CASH IN HAND STUFF, BIRTHDAYS, WEDDINGS, CHRISTENINGS, AND ONE OF THE FIRMS I WORKED FOR WAS HIRED TO WORK AT THE RECEPTION.

I WASN'T SURE I COULD GO THROUGH WITH IT, BUT THEN I HEARD HIM BOASTING ABOUT HOW MUCH MONEY HE'D DONATED FOR A BLOODY BOOK, AND EVERYONE WAS PRAISING HIM, TELLING HIM HOW GENEROUS HE WAS... AND MY LINA'S LYING SICK IN THE HOSPITAL.

THAT MADE MY BLOOD BOIL.

[INDISTINCT CHATTER] [DRAMATIC MUSIC] BUT THEN SOMEONE TOOK THE GLASS BEFORE I HAD A CHANCE TO GIVE IT TO HIM, AND THERE WAS NOTHING I COULD DO.

[COUGHS] [GAGS] [CRASH] [GUESTS GASP] I KNEW THAT SCUM HAD MURDERED MY HUSBAND...

BUT I COULDN'T SAY ANYTHING, COULD I, BECAUSE THEN YOU'D ARREST ME, AND LINA WOULD BE ON HER OWN.

WHAT'S GOING TO HAPPEN TO MY BABY?

LISA: SHE IS BEING TAKEN CARE OF, MRS. FELL.

YOU DON'T HAVE TO WORRY.

[SNIFFLES] POOR LITTLE FISH.

PROFESSOR T.: I HAVE STUDIED YOUR PAPERS WITH THE CLOSEST OF ATTENTION, AND I HAVE TO SAY NOT A SINGLE ONE SHOWS THE SLIGHTEST SIGN OF CLARITY, INSIGHT, OR INTELLIGENCE.

INSTEAD, I PROPOSE TO READ AN EXTRACT ON THE NATURE OF A CRIMINAL BY A FORMER STUDENT, WHO HAPPENS TO BE IN POSSESSION OF A FIRST-CLASS MIND.

"CRIMINALITY AND BRUTALITY ARE NOT AN INEVITABLE INHERITANCE "FROM OUR BESTIAL FOREBEARS.
