Chasing fleeing carjackers David Mapstone stumbles onto human skeletons. It is soon discovered that the remains are from a 1941 kidnapping case. David is a history professor who works for the sheriff’s office in solving cold case files and is put on this case immediately. The investigation may seem straightforward but the case involves a powerful family that has its own secrets. At the same time, investigators are trying to track down a serial killer but have no leads. Cactus Heart by John Talton actually takes place in 1999 and is a hardboiled story that pulls no punches. This is the latest book in the David Mapstone mystery series.
