A Thief in the Night is a 1905 collection of short stories by Ernest William Hornung, featuring his popular character A. J. Raffles. It was the third book in the series, and the final collection of short stories. In it, Raffles, a gentleman thief, commits a number of burglaries in late Victorian England. Although Raffles had been killed in the Second Boer War at the end of The Black Mask, chronicler and accomplice Bunny Manders narrates additional adventures which he had previously omitted, from various points in their criminal careers.
