Crime en deux temps, or “crime in two stages,” was originally released in 1939 as The Case of the Rolling Bones. For some reason the French publishers of this book, Presses de la Cité, call legendary mystery author Erle Stanley Gardner just Stanley Gardner, which sounds, well, non-legendary. Stanley Gardner is a guy at the office you don’t talk to because he’s a skin picker. Erle Stanley Gardner is a guy who, if he likes you, can get you into Nobu. So, the Erle is needed.
Plotwise, this revolves around greed, gold, and a group of people who want to prevent their relative from losing his fortune to his prospective wife. In order to stop this imagined horror, they commit the relative to a nuthouse before he can get married. Which backfires when he escapes. As always with Gardner there’s a murder, which brings Perry Mason onto the scene to sort everything out.
As you might guess, because Gardner was (and is) an immensely popular author there are several English language paperback covers for this, and they all feature dice in some form. Which makes sense, because the original title came about because there’s an actual die maker in the book. He makes crooked dice, and he gets murdered. This uncredited French cover from 1950 caught our eye because of its non-literal approach. No dice, but it’s a winner.
