Death of a Valentine by M.C. Beaton

Hamish MacBeth has been assigned an assistant, but he wasn't expecting the pretty, outgoing Josie McSween. Josie is more interested in becoming Mrs. MacBeth than in investigating the murder of a local beauty queen. The beauty queen--all agreed she was a lovely, kind girl with no faults--is discovered to be a manipulative, vindictive troublemaker.

In the previous MacBeth adventures, Hamish is pursued by attractive females but they never get him to the altar. He solves the crime while enraging his superiors. This one is no different, but it's a fun, light read, just right for a cold winter's night.
