Ellery Queen is the pseudonym of two cousins: Frederick Denny (1905-1982) and Manfred Lee (1905-1971). They are the authors of 25 detective stories, which are united by a common hero, detective and author of crime novels, Ellery Queen, whose fame matches that of Sherlock Holmes and Hercule Poirot. The work of the co-author brothers generally falls into the mainstream of a classic detective story, where there are quite a lot of confusing logical moves, false leads, and ingenious traps.
