Obsessions Can Be Murder — Connie Shelton

Albuquerque private investigator Charlie Parker becomes involved in an unsolved mystery in the small town of Watson's Lake, New Mexico. A wealthy local man, David Simmons, has been missing for four years after an explosion destroyed his house and killed a young woman. The man's wife, a gold digger named Earleen, wants to find her husband--and his money. David's daughter, Amanda, just wants to unravel the mystery surrounding her father's disappearance.

But when a body is recovered from a submerged car, Charlie realizes that layers of secrecy surround Simmons's life and possible death--especially when a safety-deposit box reveals more questions than answers. For example, was David Simmons really who he pretended to be? Now Charlie is racing to unravel a twisted trail of money and murder--before a killer decides to stop her snooping the hard way.
