Caught between two rival gangs, Sam Whistler must act as God's agent in Purgatory! Sam Whistler can't remember who he is, what he's done, or why he is Here. What he's been told is that Here is the place between Heaven and Hell...and that he's been recruited by God to set things right Here. Sam's second case begins "Here" As the freshly spawned gang war between Ma and Jones rages across the supernatural metropolis, Sam is enlisted by the new powers-that-be to infiltrate the amorphous Boroughs of the city in search of a terrorist cell planning to wreak havoc on the fabric of Here itself. Collects issues #4-8 of the supernatural crime series, Dead Letters.
