French detective, French cake, French apéritif. Literary flavour 🙂
Maigret had quite a few clues to follow and deduce from in this story, though it was, as usual, his psychological insight into victim and perpetrator that led him to the solution.
Unusually, I figured out the key elements of the MO early on, but probably only because it has similarities to one of Doyle's Holmes stories: 🔎⚡🔨⚡🌉
