Death of a Doxy

the long version

Orrie Cather is engaged to Jill, but he's been seeing Isabel on the side. When he asks Archie Goodwin to break into her apartment and retrieve some incriminating paperwork, Archie agrees - but finds Isabel bludgeoned to death. Wolfe sets out to clear Orrie of the crime, and in doing so uncovers secrets about Isabel and her love life that a number of people would rather stay hidden. Isabel's best friend, a showgirl named Julie Jacquette, decides to take a hand, and the immovable force (Nero Wolfe) just may have met the irresistable object.
