Seth is the oppressed kitchen boy at the remote Last Chance Hotel, owned by the nasty Bunn family. His only friend is his black cat, Nightshade. But when a strange gathering of magicians arrives for dinner, kindly Dr Thallomius is poisoned by Seth’s special dessert. A locked-room murder investigation ensues-and Seth is the main suspect. The funny thing is, he’s innocent… can he solve the mystery and clear his name, especially when magic’s afoot?
