The Devil's Twin

Twenty some odd years ago, Sheila Compton was a beautiful
wife and mother of twins, Denise and David. Her twin,
Leslie, who had made her life miserable all her life had
moved, never to be heard from again. Then terrible things starting
happening: Sheila's parents were killed in what police deemed a
robbery gone bad, her husband was killed by a drunk driver and her
children disappeared without a trace.
Now twenty years later, retired CIA agent, Sandy Shores Landow,
has been asked to take a look at the case. After all, women think
differently than men, right? Then bad things start happening to her
also. What is the cause? What devil is at work? When her husband
gets shot and someone tries to kill her also, Sandy decides it's time to
try to solve the mystery.
