Dead Heat. Partners in Crime, #6

When the team is called to a scene outside the high school with multiple deaths, they knew it was going to be bad. Tyler is the cousin of their Lieutenant's new wife, and a veteran with PTSD. He tries to tell them a ghost made him do it. "The ghost made him do it, " Jamie muttered. "Yeah, this doesn't sound good at all."In a race against time, Jack, Jamie, and Mike are in a dead heat between the living and the ghosts.
Local legends speak of the 'shadow man', a dark shadow of a man with glowing red eyes. Some say it's the ghost of a pirate from the 1800s, others call it a demon, but the newest ghosts know it's what killed them - and it's nothing good. The dead are piling up and they're going to have to work with the Watchers to stop a serial killer ghost. As more mass casualty events happen all over the city, with no logical connection, panic and fear take over.
There's only one connection - the shadow man - and it's not one they can release to the public and still be taken seriously. The race against time is a dead heat between the team and the entity-and there's no guarantee the team will win.
