A mysterious beast is terrorizing the resident skeletons of Bonesville. Under cover of darkness, it steals a different bone from each townsperson, from cranium to phalanges. It takes the washerwoman's humerus, the butcher's fibula, and Dr. Strongbones's coccyx. Thanks to his patience and cleverness, Detective Sherlock Bones traps the monster, revealing that the beast is only the harmless Spot of the Baskervilles, on a mission to rebuild the lost skeleton of his master, Dr. Watsbones. Jolivet's bold illustrations and Fromental's witty storytelling make for a winning combination in this striking picture book, perfect for young Sherlock Holmes fans.
