A playful, page-turning murder mystery perfect for fans of The Traitors. In an ancient castle on a remote island, thirteen children gather to play a game. The rules are simple: uncover the secret "Murderers" before they eliminate the "Innocents". It may sound easy - but it soon turns deadly. A real murder throws the competition into chaos, and Jenny Twistle finds herself caught in a mystery far more dangerous than the one she came to solve. With the help of her loyal-but-cowardly dog Ruff, and frenemy Brad, can Jenny defy the odds, solve the mystery, and take home the prize? It'll be tough, especially when it's almost impossible to tell who's lying, who's playing a game, and who's willing to kill to win... This is The Swifts meets The Mysterious Benedict Society with a touch of Lemony Snicket!
