The Unlatched Door

The Unlatched Door, first published in 1920, marks the first appearance of detective Peter Clancy. During her long career, author Emma Redington Lee Thayer (1874-1973) published 60 novels, all but one featuring Clancy, who begins his career with the police; later books have Clancy working as a private detective. Clancy is also later joined by his trusty valet Wiggars, who first appears in the tenth book of the series: Dead Man’s Shoes (1929).
