Ellery Queen is the pseudonym of two cousins: Frederick Dannay (1905–1982) and Manfred Lee (1905–1971). They wrote 25 detective novels, united by a common hero—the detective and crime novelist Ellery Queen—whose fame is on par with that of Sherlock Holmes and Hercule Poirot. The brothers’ co-authored work largely follows the classic detective tradition, where there are plenty of intricate logical turns, false leads, and ingenious traps. “The Calendar of Crimes” is a collection of twelve stories—one for each month of the year.
