In 1930, Anthony Berkeley Cox (1893-1971) founded London's Detection Club, whose members swore that their "detectives shall well and truly detect the crimes presented to them, using those wits which it may please you to bestow upon them." The Detection Club pledged "never to conceal a vital clue from the reader." Anthony Berkeley's novels and short stories featuring Roger Sheringham and Inspector Moresby are among the finest examples of the fair play, challenge-to-the-reader tradition of the Golden Age. The title story in The Avenging Chance has long been considered one of the greatest formal detective stories. This book also collects all the additional cases of Sheringham and Moresby. This enlarged edition includes - for the first time- the newly discovered short stories, "The Bargee's Holiday" and "Hot Steel." Cover illustration by Gail Cross.
