Cat of Many Tails

Ellery Queen was a pen name created and shared by two cousins, Frederic Dannay (1905–1982) and Manfred B. Lee (1905–1971), as well as the name of their most famous detective. Born in Brooklyn, they spent forty-two years writing, editing, and anthologizing under the name, gaining a reputation as the foremost American authors of the Golden Age "fair play" mystery. Besides writing the Queen novels, Dannay and Lee cofounded Ellery Queen's Mystery Magazine, one of the most influential crime publications of all time. Although Dannay outlived his cousin by nine years, he retired Queen upon Lee's death in 1971.
