Counterfeit

Counterfeit, first published in 1933, features private investigator Peter Clancy, assisted by his valet Wiggars. Author Emma Redington Lee Thayer (1874-1973) published 60 novels during her long career, all but one featuring detective Peter Clancy. From the dustjacket: "Three men are dining together in a brilliant New York restaurant. Red-headed Peter Clancy, private investigator, is host. Raymond Trant, of the Secret Service, and Captain of Detectives Kerrigan are his carefree guests. As a matter of personal interest Trant tells them of a wonderful counterfeit one hundred dollar bill that he is deeply concerned in tracking to its lair."
