Profit motive…
😀 😀 😀 😀 😀
The Joymount Cement Company is in trouble. Its main local competitor, Chayle’s, has found a new formula that allows them to produce cement more cheaply, thus undercutting Joymount. Joymount’s board of directors decide to give their chief chemist a few weeks to try to replicate the formula – if he fails, then the company may have to close. King, the chemist, tries his best but, as the deadline approaches, he is no nearer finding the solution, so he persuades one of the other directors, Brand, to sneak into Chayle’s with him one night to see what they can find out. That’s when things begin to go horribly wrong…
This is an “inverted” mystery, a format for which I understand Crofts was particularly well known. (For the uninitiated, this means that the crime is shown first including the identity of the criminal, and then the story joins the detective, showing the methods he uses to investigate it.) The story leading up to the break-in at Chayle’s and the resulting death that happens there is very well told, but only takes up about a quarter of the book. Inspector French from Scotland Yard is brought in because the local police suspect that there’s more to the break-in and death at Chayle’s than meets the eye. French soon confirms this, and now a murder hunt is on.
At this point, I was thinking that it was going to be a long haul watching French discover what we, the readers, already knew had happened. I should have had more faith in Crofts’ reputation! I can only be vague because I want to avoid even the smallest of spoilers, but suddenly another event happens that turns the story on its head, leading to another crime – one to which the reader does not know the solution. This second crime forms the main focus of the book, and a very satisfying mystery it is. The possible suspect list is tiny, but the clues are so beautifully meted out that I changed my mind several times about whodunit, and only got about halfway there in the end. It’s also a howdunit – until the method is discovered, it’s almost impossible to know who would have had the opportunity to commit the crime. So in the end, Crofts throws in everything – an inverted crime, a traditional mystery, alibis, method, motives, all wrapped up in a police procedural, and it all works brilliantly.

He also does a lovely job with the characterisation – not so much of French, who truthfully is a bit bland as detectives go, in this one at any rate, but of the men involved – King, Brand, their boss Tasker, and their opposite numbers at Chayle’s. They are each given clear motivation for how they act individually, and there’s a good deal of moral ambiguity floating around – while not everyone is guilty in the eyes of the law, very few could be called entirely innocent. The murkiness of the business world is at the heart of the story, and the lengths to which men will go in the pursuit of profit. (Yes, they’re all men – it was first published in 1934.)
I loved this. So intricately plotted but also with a very human set of characters to stop it from being merely a puzzle. It’s only the second book of Crofts I’ve read, the other being The 12:30 from Croydon, which I also thoroughly enjoyed. It too is an inverted mystery, but very different in how it’s done, showing that this particular sub-genre has more room for variety than I’d have expected. I will now add Crofts to my ever-growing list of vintage crime writers to be further explored! Happily I have another couple of his books already waiting on the TBR pile…
