Ellery Queen is one of the world’s finest detectives, but his adventures are nothing compared to these vintage Ellery Queen Jr. Mystery Stories, written between 1942 and 1966. The first nine books in the series, starting with The Black Dog Mystery, star Djuna, Ellery’s young employee, who teams up with his scrappy terrier, Champ, to catch bank robbers, smugglers, and the worst his small town’s underworld has to offer. The last two books in the series, The Mystery of the Merry Magician and The Mystery of the Vanished Victim, star Ellery’s cheeky nephew, Gully, whose adventures take him to the darkest corners of Manhattan.
