A Share in Death by Deborah Crombie

It's been a long time since I read one of Crombie's books, and I'm not sure I ever read this one. Crombie is American writing in a British setting. Duncan Kincaid is a Superintendent at Scotland Yard; his sergeant, Gemma James, is a single mother with red hair and freckles.

British detectives and their sergeants, at least in fiction, seem to develop a sort of symbiotic relationship, and these two are no exception. In this story they actually are working separately, but the connection is still apparent.

As for the story, we have a series of murders at the British equivalent of a timeshare where Kincaid is a guest courtesy of his cousin who is unable to use his week. Every guest - and member of the staff - has a hidden agenda. These agendas intersect in any number of ways and with curious results.
