Pursuit by Thomas Perry

I enjoyed this and will look for another book with Roy Prescott. Thirteen bodies are found in a Louisville restaurant. When the police can find no suspect or motive, a victim’s family seeks the services of the enigmatic and solitary specialist Roy Prescott, known for his ability to find people who don’t want to be found. Working outside the law and willing to do what the police can’t, Prescott hunts the killer, an elusive adversary who is as smart, as methodical, as deadly as he is. The only way to conduct this pursuit is to goad the killer into believing that he must kill Roy Prescott. It is a contest fought from one end of the country to the other, and both men understand that when it’s over, only one of them will be alive.
