White Nights: Ann Cleeves

Cleeve sets this group of novels in the Shetland Islands, north of Scotland. This is the second in the series, the first being Raven Black. The island is a tourist trap in the summer and Detective Jimmy Perez hunts down a killer of three, one a tourist, two, locals. Cleeve's modus operandi is to give the reader brief biographies of practically everyone in the novel, making it difficult to figure out who done it till the end.
