R.I.P.D.: City of the Damned #1
Roy Pulsipher and Nick Walker are dead, but that doesn't mean their time in law enforcement is over. Both Roy and Nick are officers in the Rest in Peace Department, sworn to serve the Almighty and protect the living from evil's foul corruption. Their current case has them chasing a ghostly fanatic determined to undo all of creation-a threat with very personal connections to Roy's past, stretching back a hundred years into a weird, Wild West and Roy's first day on the job. It's a twisted history that Nick is only starting to uncover, and one that could have him reconsidering ever joining the R.I.P.D.!
