Four women were murdered, each was knifed and, though they had their clothes torn, they weren't molested. As the famed police inspector Jules Maigret pieces the clues together, he comes to realize that for the elusive man that he suspects to be unmasked, he has to set him a trap.

The wife and mistress of a sadistic boarding school headmaster plot to kill him. They drown him in the bathtub and dump the body in the school's filthy swimming pool... but when the pool is drained, the body has disappeared - and subsequent reported sightings of the headmaster slowly drive his 'killers' (and the audience) up the wall with almost unbearable suspense...
