The Monster of Florence by Douglas Preston

The true story by author Douglas Preston about a serial killer of lovers in Florence, his investigation into who it may be and much more I can't put without giving anything away. You almost need a scorecard to keep up with everything but it is well worth it. I started this early this am and finished up tonight; I couldn't put it down. It's like trying to find the one armed from The Fugitive to who is Keyser Soze from The Usual Suspects. Deals with murders committed over a span of 20 years, a missing gun, a motive, a corrupt police department, planting evidence, Preston being questioned as a suspect, satanic cults dating back to medieval times, and the ultimate question.....who is the Monster of Florence?
