From Rex Stout's Nero Wolfe and Archie Goodwin, to Agatha Christie's Mr. Satterthwaite and Harley Quin, to Patrick Quentin's Peter and Iris Duluth, to Marcia Muller's Sharon McCone and Rae Kelleher, Muller and Pronzini have gathered a treasure chest of stories featuring almost every possible variation on the types of partnership sleuths. Imitations of -- and the original -- Holmes and Watson tandem appear alongside husband and wife teams, two-woman duos, professional and amateur duos, multi-ethnic parings, and collaborations between two writers and their individual series characters. Spanning more than a century of crime fiction, including both classic tales by the greats of mystery writing as well as outstanding stories from contemporary writers, Detective Duos will captivate the sleuth in all of us.
