Dickson, Carter. The department of queer complaints. New York: William Morrow and Company, 1940.
Summary: Eleven stories centered on odd, weird, or deviously contrived events, most of which are naturalistically accounted for by an modestly insightful police inspector at Scotland Yard, a former Army colonel.
The genre of thrillers has advanced so much in the decades since Dickson's stories were written that his supposedly puzzling events can barely attract the jaded reader's interest, and several of the explanations seem anticlimactic.
