The Priority Unit — Susan Page Davis

A missing man. A mysterious computer program--even the people constructing it don't know what it will do. Detective Harvey Larson was good at keeping his personal life out of his professional life--until he met Jennifer Wainthrop. The beautiful software designer was the last person to admit seeing Nick Dunham alive. Can Harvey find out what happened to her missing coworker before someone else gets killed? The killer has learned who is stalking him, and everyone associated with Harvey is in danger. He struggles for the strength he needs to protect Jennifer from the same grim fate that claimed Nick, while serving up Maine Justice.
