When the housekeeper of a New York City magnate reports that a young woman from her staff has gone missing, both the disappearance and the housekeeper’s behavior strike the police as odd. The senior detective, Mr. Gryce , detects a few decisive clues which elude his younger colleague charged with the investigation, Q.

A Strange Disappearance is the second outing for Mr. Gryce. Much like the earlier novel, The Leavenworth Case , he does not often take center stage, but his interventions are decisive in unravelling the mystery.
