Karma Killer ... a sequel to Mindmaze

In Mindmaze, Mike Vaughn was a young man who had it all, a good job, a wife and two kids. But, beneath the facade, he was a serial killer whose bloody crimes were finally revealed to him by his alternate personality, Dylan. Together, they committed and concealed crimes across the United States for years. But all good things must come to an end and they were captured and locked away in an institution for the criminally insane.
Now, twenty-five years later, Mike's/Dylan's children go home to Reading to start new lives. Rachel has a new boyfriend who is helping her overcome her traumatic past. Ricky, a police officer, is investigating a series of murders that are beginning to look all too familiar ... too close to home. Ricky is frustrated by the crimes he cannot seem to solve, and the past he cannot seem to shake. Could this be karma?
