The Author’s Guide to Murder by Beatriz Williams

There’s been a sensational murder at historic Castle Kinloch, a gothic fantasy of grey granite on a remote island in the Highlands of Scotland. Literary superstar Brett Saffron Presley has been found dead—under bizarre circumstances—in the castle tower’s book-lined study. Years ago, Presley purchased the castle as a showpiece for his brand and to lure paying guests with a taste for writerly glamour. Now it seems, the castle has done him in…or, possibly, one of the castle’s guests has. Detective Chief Inspector Euan McIntosh, a local with no love for literary Americans, finds himself with the unenviable task of extracting statements from three American lady novelists. 

The prime suspects are Kat de Noir, a slinky erotica writer; Cassie Pringle, a Southern mom of six juggling multiple cozy mystery series; and Emma Endicott, a New England blue blood and author of critically acclaimed historical fiction. The women claim to be best friends writing a book together, but the authors’ stories about how they know Brett Saffron Presley don’t quite line up, and the detective is getting increasingly suspicious.
