The Adventure of the Powder Room is the last novel of the Eduardo Mendoza's sarcastic trilogy including The Mystery of the Bewitched Crypt and The Labyrinth of the Olives. The funny main character is the common thread in the three books written in the specific parodical detective genre. The character is an odd nameless evildoer who is now presented in a James Bond style. The city is Barcelona in the mids of the 20's. The anonymous detective, finally released from the mental hospital, finds himself in an even crazier environment - the Catholic society where our detective is the sanest one.
