Sharp Force by Patricia Cornwell
The setting of the most recent murder (Christmas eve! a timely read as it turned out) was a mental hospital/ insane asylum which had had a sketchy history for more than a hundred years... While I enjoy reading Cornwell, and I did enjoy this ride, I found the ending to be rushed. I was not surprised to find Peanut to be important (spoiler) but the serial killer just came out of the blue. That isn't really any fun. I did find one line to be especially frightening... (aside - why frightENing but lightNing?) "Even laziness and reading too many novels could send people away for the rest of their days..."
