One morning in February, an unknown person telephones Inspector Maigret: he claims that some men have been chasing him since the night before and he is convinced that his life is in danger. The call is interrupted and repeated from various cafes in Paris, until finally the phone stops ringing. That same night, the corpse of a young man with a disfigured face appears in Place de la Concorde, and Maigret is convinced that it is the same man who telephoned him. From that moment on, the inspector feels that he must personally take care of that dead man, discover who he is, what he did, and why he died in such a mysterious and shocking way. Simenon creates a new masterful plot in which moments of tense calm alternate with those of frenetic action, and takes advantage of the interludes to give the touches of humor and humanity that make Inspector Maigret one of the most emblematic characters in the crime novel.
