Book excerpt: Lizzie Snow was first introduced in the final book of Graves's previous series, BAT IN THE BELFRY, in which she helped Jake Tiptree find who killed a girl and left her body in a church steeple. Now Lizzie has taken over as Eastport's police chief, and is quickly finding the job - and her life - more complicated than she expected. Then she learns that someone seems to be killing retired detectives in the state... and that she has been followed from Boston to Maine by a mysterious stalker whose chilling intentions will drive her to the edge.
