The famous detective Matthew Gatiadis, a very clever cat with a thick black and white fur coat, and his close friend Beatrice Gourmet travel to Scotland to spend Christmas in the Gaterville tower.
Legend has it that the medieval tower is haunted. And indeed, the kind hostess Lady Mary Gaterville begins to see the cursed ghosts of her ancestors threatening her: the knight Richard Gaterville wields a sword ready to strike, and his unfortunate wife, Alice, appears as a white apparition, wearing a long wedding dress.
Matthew immediately takes action! Which of the guests in the tower are pretending to be ghosts, and why do they want to terrorize the wealthy Lady Mary?
Will Matthew be able to unmask the culprits before it's too late?
