Death of a Ghost, Paperback Book, By: M. C. Beaton

Sergeant Hamish Macbeth--Scotland's most quick-witted but unambitious policeman returns in M.C. Beaton's new mystery in her New York Times bestselling series. From the author of the Agatha Raisin series. When Police Sergeant Hamish Macbeth hears reports of a haunted castle near Drim, he assumes the eerie noises and lights reported by the villagers are just local teenagers going there to smoke pot or, worse, inject themselves with drugs. Still, Hamish decides that he and his policeman, Charlie "Clumsy" Carson, will spend the night at the ruined castle to get to the bottom of the rumors once and for all. There's no sign of any ghost but then Charlie disappears through the floor. It turns out he's fallen into the cellar. And what Hamish and Charlie find there is worse than a ghost: a dead body propped against the wall. Waiting for help to arrive, Hamish and Charlie leave the castle just for a moment to eat bacon baps but when they return, the body is nowhere to be seen. It's clear something strange and deadly is going on at the castle, and Hamish must get to the bottom of it before the "ghost" can strike again
