The Crime on the Rue de Lourcine

After a night of carousing, the respectable Monsieur Lenglume wakes up in his own bed beside a complete stranger! A hangover does not sit well with memory, but eventually the two work it out: Lenglume and Mistingue are old schoolmates who met at a reunion of former pupils. So far, so good. But what are a bonnet, a lock of hair, a woman's shoe and, above all, a lump of coal doing in their pockets? Neither of them remembers a thing. Then, glancing over the morning paper at breakfast - horror! During the night a poor coal-seller was murdered, and the police are already on the killers' trail. The two begin to suspect that, their minds fogged by drink, they committed the abominable deed together. Only one thing can still be done: the evidence must disappear, and the witnesses to the crime... must be eliminated!
