Commissar Maigret isn’t new to complications—but to make something like this happen! The brave commissar is ready to ride an ordinary bicycle for dozens of kilometers in pursuit of the truth. The reason is simple: on the rich yacht of a retired military officer, a loafer, a bunch of sluggards and drunks—there was a double murder. As passengers on the yacht, the owner’s associate and his wife didn’t think things would turn out this way. And yet it was precisely they who became the victims for which Maigret took such a long journey. But for the commissar, there are no crimes he can’t solve. And this time it will be just like always: the killer will be found despite the tangled case and the inexplicable silence of potential witnesses.
