Painter Mann has spent his afterlife in the InBetween helping other ghosts move on to whatever's next. Eventually, he'll want to make that leap too, but to do that, he'll need to discover the name of the person who murdered him. Painter, the world's only dead private investigator, goes to New Orleans hoping to learn the identity of his killer.

Instead, he gets wrapped up in a case where he must find and rescue hundreds of missing ghosts.

To do that, he'll have to tangle with two-headed monsters, a psychotic dead DJ, enemies with supernatural powers, and the mysterious Voodoo Cher. He's also being "hunted" by the Ghost Wranglers, a popular cable TV show determined to hunt down the ghost PI known as Painter Mann.
