Police Constable Hamish Macbeth is miserable. He's sick . . . and no one seems to notice. He also is looking forward to visiting his family on his Christmas holiday . . . until he's warned off because his aunt who cannot stand him is coming from America. In a foul mood, he's not too excited when Priscilla Hallburton-Smythe asks him to talk to a guest, Jane Wetherby, at the family hotel (formerly the family castle) about two brushes with death and an inauspicious tea leaf reading. Meeting Jane, he's quickly impressed by her looks, her wealth, and her health farm (the Happy Wanderer) on remote Eileencraig. His mood lifts when he's able to inveigle an invitation for a free trip over Christmas to "look into things there." He leaves the exhausted Priscilla to trek to his parents' home to deliver Christmas presents in a terrible blizzard . . . and promptly forgets about her while becoming intrigued by the widowed cookbook author, Harriet Shaw, who becomes Dr. Watson to his Sherlock Holmes.
Naturally, Hamish is trying to fit in with the other guests . . . and not indicate that he's a policeman on holiday with a purpose. Choosing a cover as a forester, he's ripped up one side and down the other by one of the guests, Heather Todd, who is a social climbing communist sympathizer who favors any trendy left-wing cause for which she can hold a party. But you cannot blame Heather too much for her self-absorption: Her husband mainly likes to admire himself in the mirror. The other guests don't endear themselves to Hamish very much either. He soon wishes that he were anywhere else. And then, mysterious events start to occur. Jane disappears, and Hamish sets out to find her. Then one of the guests disappears and the search is even more challenging.
The mystery is a delightful one, with fair clues to help you figure out who did what to whom. The detection process is also fun. Hamish's attraction to Heather provides lots of amusing scenes. Priscilla's Christmas story will be one you'll long think about.
The book's only weakness is that the victim is painted in harsher colors than are needed for the story. That creates a memorable character, but hardly a realistic one.
