The Ex Who Saw a Ghost — Sally Berneathy

Five bodies in a well. One of them is the brother of a police detective. That man's ghost is Charley's new best friend. Amanda is thrilled that Charley can see him. Perhaps this means her ex-husband's ghost is on his way to the light, to a higher plane, to Oklahoma, to anywhere so long as it's away from her.But the new ghost isn't leaving. He has an agenda, and it doesn't involve finding his killer. Amanda, Charley, Jake, the medium Teresa, and the ghost's brother Ross must hunt down his murderer before one of them is killed. Charley's not worried, but the others don't have his immunity to death.
