I’m very pleased to announce that the thing that has been driving me half mad for two years is called The Researcher’s First Murder. I very much hope it will do the same to you later this year. But frankly even if, like a sensible person, you take one look at the postcards and throw them in the fire before they can get their hooks into you, the money will be well spent just for the box; thanks to the gorgeous cover illustration by Tom Gauld. I mean, just look at it. I have loved Tom’s work for years (I would tell you to check out his cartoons in the Guardian and the New Scientist, but who the hell do I think I am? Naturally you know all about them already) and it is a matter of great joy to me that I have caused him to draw a pangolin. As for the thing itself – the nature of it means that I can’t tell you very much about the plot or the characters, because Unbound, out of the simple goodness of their heart, are going to offer you £1000* for you to tell me about them. But I can tell you something about the structure of the puzzles. On one side of the hundred postcards are jumbled pages from a narrative, which must first be arranged into the proper order, and then fully understood, to reveal the whole story of a series of extraordinary murders that occurred in 2023. On the other side, the images on the postcards fall very obviously into ten sets of ten, each of which is a self-contained puzzle. The mechanisms of these puzzles, and types of puzzling skill required to solve them, are as different from one another as I’ve been able to make them. My hope, therefore, is that everyone who enjoys puzzles of some kind will find something to enjoy in it, and so very few people will come away without having been able to solve some part of it… but that even fewer will be able to solve absolutely everything. But even if you get nowhere… there is, as I say, always the pangolin. JF * Unbound are offering a prize of £1000 for the first person to successfully complete The Researcher’s First Murder within six months of publication.

Update from John Finnemore

Can you solve The Researcher’s First Murder? In 1934, the Observer’s crossword compiler, Edward Powys Mathers, wrote a unique novel: Cain’s Jawbone. The title, referring to the first recorded murder weapon, was written under the pen name of Torquemada. The story was not only a murder mystery but one of the hardest and most beguiling word puzzles ever published. In 2019, Unbound re-published Cain’s Jawbone. Aided by word of mouth and TikTok, Cain’s Jawbone: A Novel Problem has sold almost half a million copies and been translated into fourteen languages. Only two people solved the puzzle back in the 1930s and the first person to solve it since then was the British writer and puzzler, John Finnemore. Now John has returned with his own challenge: the first murder mystery to be presented in the form of a box of picture postcards... The Competition In 1934 a prize of £15 was offered to the first reader who could reorder the pages and provide an account of the six persons murdered in Cain’s Jawbone and all the names of their murderers. In the spirit of Torquemada we are going to host a competition for The Researcher’s First Murder which will close at midnight GMT on Friday 28th February 2025. Unbound will be offering a £1,000 cash prize to the first person who successfully solves John Finnemore’s murder mystery within this time frame. We will also be offering £250 to one successful runner-up, who will be selected at random from any other correct entries submitted after the winning entry and before the closing date. Necessary elements for a complete solution: A list of the first and last names of both the murderer and victim in each of the ten murders. The location where each murder took place (village, town or city). The full address of where the final victim was found (including: Flat, House name, Number, Street, Village, Post town, County, Postcode). We will accept photographs or scans of a completed answer sheet from the booklet provided in The Researcher’s First Murder box. You can submit an entry by sending a completed answer sheet via email to researchersfirstmurder@unbound.co.uk Terms and Conditions Entries received after the closing date (midnight GMT on Friday 28 February 2025) will not be accepted.
