The Devil's Pet Baits: "A Melee of Diamonds" (1972) by Edward D. Hoch

Edward D. Hoch's "A Melee of Diamonds," originally published in the April, 1972, issue of Alfred Hitchcock's Mystery Magazine and collected in Leopold's Way (1985), begins with a crude, everyday crime – a simple smash-and-grab job. A man wielding a silver-headed cane smashes the store window of the Midtown Diamond Exchange to pocket a modest fortune in diamond rings and unset stones, but a patrolling police officer is immediately on the scene. And gets knocked down with the cane. Fortunately, a bystander chases the thief, wrestles him to the ground and hands him over to the police. So case closed, except for one small, all-important, detail: what happened to the diamonds?

The thief, Rudy Hoffman from New York, took $58,000 worth of diamonds from the broken store window before getting apprehended half a block away. From the time Hoffman smashed the store window to the moment he was tackled to the ground, "he was in sight of at least one person every instant until they arrested him." However, Hoffman didn't have a single diamond on him. The police searched him, the street and they "even searched the patrol car he was in after his arrest" without finding a single diamond ring or unset stone. Hoffman isn't talking.

So when Captain Leopold hears a report the following days, he asks to have him brought down "to show you guys how it's done" with similar results. This apparently simple smash-and-grab from a store window is not one of Captain Leopold's finest hours as he's in full fallible detective mode ("this is my night for being wrong"). Even when the missing diamonds and the solution are literally gifted to him on a silver platter.

Captain Leopold pulls an impossible vanishing-act with the diamonds himself, in order to manipulate an accomplice in drawing out the main culprit, but it horribly misfires and, to use his own words, "I was trying to pull off a neat trick, and I got a guy killed" – "I bungled, that's what happened, Fletcher." Captain Leopold got it wrong one more time that night, before he can finally and successfully close the case.

So, while Captain Leopold was stuck in fallible detective mode, I played Mycroft Holmes and deduced the correct solution to the first impossibility. And, what exactly, happened the moment the store window got smashed. A not wholly unoriginal trick complimented by the smash-and-grab setup that allowed me to anticipate the identity of the main culprit. On the other hand, Leopold's trick honestly had me stumped and it's not even half as good or original as the first vanishing-trick. But it served its purpose. So, while not a perfect detective story, "A Melee of Diamonds" stands as another pretty solid, competently-plotted effort from the prolific Hoch enjoyably demonstrating the versatility of the impossible crime story outside the customary locked room and fields of virgin snow. Recommended!

Note for the curious: I also reviewed the short story collection The Killer Everyone Knew and Other Captain Leopold Stories (2023) and the Captain Leopold short story "The Oblong Room" (1967).
