The Widows of Broome

Two widows have already been murdered when Detective-Inspector Napoleon Bonaparte (as Mr. Knapp, psychiatrist) comes to Broome. The murders seem to be without reason and apparently without clues. In his patient, meticulous manner, Bony collects infinitesimal facts and begins to build a picture of the murderer, but he becomes increasingly disturbed as the moon grows old and he feels that there might be another murder. A third murder is committed, but Bony has acquired enough facts to lay a trap for the murderer, avert the fourth crime, and expose the killer.
