Chasing Ghosts — David Archer

Sam and Indie take on their strangest case ever, when they're asked to help prove that a cameraman for a ghost chaser TV show did not murder a policeman. The case brings them into a world of ghosts such as they never imagined, and Beauregard and Grace are front and center as they try to identify and stop a killer. Then, when all seems lost, Sam finally manages to prove who was truly guilty, but the result is something none of them ever could have foreseen.
