In this crime thriller, Detective Philip Lansing hasn’t been getting enough sleep. As an investigator from the Weston, Minnesota Police Department, it’s his job to track down a murderer terrorizing his small town. He isn’t in it alone; his partner, Tom Johnson, is investigating the series of murders as well. This is a first for everyone – a serial killer in Weston a small town in the midwest. There really is very little to go on for the investigators, no physical evidence, no DNA, fingerprints, or witnesses. Lansing and Johnson find themselves with two new partners, Agents Ana Monroe and Charlie Radford of the Minneapolis FBI Field Office. The four investigators begin an alliance to capture the murderer. A tunnel and cave plus a large, ancient book in Latin hold the key to the mystery.
