Two brave young sleuths connected to one of the greatest detectives of all time tackle their own cases in these eleven whodunits.

For mystery fans, the name Ellery Queen brings to mind the sophisticated amateur sleuth who helped solve some of New York City’s most confounding cases. But he wasn’t the only one in his household with an eye for crime solving.

Here are eleven puzzling mysteries, nine solved by Djuna, the Queen family’s quick-witted assistant, with the help of his trusty Scottie, Champ; and two solved by Gulliver Queen—the chip-off-the-old-block nephew to the legendary detective himself.

Djuna solves The Black Dog Mystery, The Golden Eagle Mystery, The Green Turtle Mystery, The Red Chipmunk Mystery, The Brown Fox Mystery, The White Elephant Mystery, The Yellow Cat Mystery, The Blue Herring Mystery, and The Purple Bird Mystery.

Gulliver solves The Mystery of the Merry Magician and The Mystery of the Vanished Victim.
