Cain's Jawbone is a 1934 literary puzzle by Edward Powys Mathers, pen name Torquemada. 100 scrambled pages, six murders, no key, no instructions, and only four verified solutions in ninety years.

In a bid to live up to the the Real Life Sherlock title I have been given. Professionally, on stage, on camera, that name is the whole premise, read people, catch what others miss, work it out before anyone else does. This book does not care what I go by. 20 pages in, and it's taken longer than I'd like to admit for the method to start paying off. But it finally is.

Every detail I've checked has turned out to be doing real work, real quotations, real history, real legal language buried in places it shouldn't be. And one name keeps turning up in completely different rooms of this book, wearing a completely different mood each time. I'm not telling you the name. I'm not telling you the pages. But I'll tell you the book rewards suspicion, and I've stopped trusting anyone in it, including the narrator.

This episode also opens the actual toolkit, the real literary techniques a book like this uses to hide things in plain sight, so you can start spotting them yourself before I say another word.

No spoilers. Not when I finish, not ever. Every viewer gets the same blank page I got, including the Real Life Sherlock.

Follow along. This is going to take a while.

Ai is here and David Clarke spent his career catching fraudsters, first as a City of London Police Fraud Squad chief, then building the National Fraud Intelligence Bureau from the ground up. Now he's watching artificial intelligence industrialise the exact crime he built his life around stopping. This conversation is about what happens when the con artist never sleeps, never runs out of voices, and gets smarter every week.

In this episode:

David explains how AI has moved fraud from mass blast scams to attacks personalised to the individual victim, and why that shift is the one nobody's prepared for. He walks through why he calls the current fraud landscape the worst he's seen in 45 years, official statistics included, and where those statistics are quietly undercounting the real damage. He breaks down AMLiss, the tool he built to catch red flags buried inside multilingual contracts and business communications before they become a problem. He makes the case that expecting ordinary people to spot deepfake fraud on their own is naive, and lays out what should replace that expectation instead. He pitches his "Digital Fortress" concept, a nationwide system linking banks, telecoms, and law enforcement against AI driven crime, and argues for who should be running it. He talks through what actually changes moving from fraud squad detective to corporate chief security officer. And he gives the one tell that gives away an AI run scam before the money ever moves.

You didn't choose that option. Something built the room you chose it in, and it built the room before you walked in.

In this episode:
– What choice architecture actually is and why nudge theory changed behavioural economics
– The organ donation study that proves a default can move outcomes by 75 percentage points
– Why AI personalisation turned nudge theory from a blunt tool into an individual weapon
– The decoy effect and how a bad third option sells the expensive one
– Dark patterns: where legitimate nudging becomes manipulation, and where regulators are already drawing the line
– The sunlight test for telling the difference
– A practical audit method for finding hidden defaults in your own forms and processes

If you've ever felt like you chose something and couldn't say why, this is the episode that explains it.

I have been called a Real Life Sherlock by many folks I respect within Law Enforcement. Cain's Jawbone is the puzzle that gets to decide if that's actually earned. In 1942 a crossword got too easy, so the Daily Telegraph built one vicious enough to recruit five strangers into Bletchley Park without their knowledge. Cain's Jawbone runs the same test, except the Laurence Sterne Trust holds a verified solution, so every page I get right or wrong actually means something.

In this episode:

The true story of the 1942 Telegraph crossword that became a Bletchley Park recruitment filter

Why Cain's Jawbone sits in that same category, not in Masquerade's or Cicada 3301's

What happens when the Real Life Sherlock reputation gets thrown at a puzzle that's beaten almost everyone who's tried it

Real material lifted straight into the fiction: Defoe, Whitman, Shakespeare, Conrad, a Jacobite execution, an Egyptian cigarette brand down to the exact sizing

Arthur Conan Doyle turning up four separate times, including a dummy bell rope built exactly like the murder weapon in The Speckled Band
Evidence the narrator changes page to page, and what two possible voices sound like so far

Ten pages down, ninety to go, and why the narrator insisting they're out of their depth might be the actual lie

Everyone thinks close protection is the suit, the earpiece, the guy scanning a crowd like he's in a Statham film. It isn't. It's advance work nobody sees, a plan already three versions deep before the principal arrives, and hundreds of hours of nothing happening on purpose.

Jim Wenzel joins The Deductionist Podcast with Behavioural Intelligence to break down what close protection actually is: proactive prevention, not reactive tactics. We cover the POLAR framework (positioning, observable behaviour, location, access, risk), why "boring is best" is the real measure of success, why training for decisions beats training for drills, and why the principal should never pay for the protector's ego.

If you've ever wondered what separates someone who can read a room from someone who can act on what they've read, this is the episode.

Sherlock built his method on reading behaviour before anyone spoke a word. Turns out marriages run on the same evidence. Sue Palmer Cole, the divorce doctor and founder of the Divorce Academy, joins Ben and Bob to break down what actually predicts whether a relationship survives, and it isn't compatibility. It's adaptability, communication style and how a couple handles conflict when it shows up.

Sue walks through the real inflection points: the affair risk window during early parenthood, the brain rewiring that hits women in perimenopause, and why two thirds of divorces are instigated by women between 45 and 55. John Gottman's five to one ratio gets a mention, as does the difference between a couple leaning into a relationship versus leaning out of it.

If you've ever wondered why some marriages adapt and others just accumulate silence, this one's for you.

Before you can solve the world's hardest literary puzzle, you need to understand who built it and why.

Edward Powys Mathers was a Persian poetry translator who spent thirteen years setting cryptic crosswords for the Observer under a pseudonym borrowed from history's most enthusiastic torturer. In 1934 he published Cain's Jawbone, a 100-page murder mystery with its pages deliberately scrambled, the numbers removed, and no instructions beyond the implication that a correct order exists. Two people solved it within a year. Then it went quiet for eight decades.

In 2020, comedian and crossword compiler John Finnemore became the fourth person in history to crack it, spending four months of lockdown underlining nearly every sentence before finding the breakthrough that made the architecture visible. He swore to keep the solution secret.

He has.

This episode profiles the man who built the trap and the man who finally beat it, then I walk into chapter two of the puzzle live on camera.

Four correct solutions in ninety years. I'm attempting the fifth in public.
Solving Cain's Jawbone is a real-time investigation into the most difficult literary puzzle ever published. New episodes as the case develops.
