There's a new sheriff in town, and he's got the Nightside's rich and powerful quaking in their boots. He's The Walking Man, and it's his mission to exorcise sinners — with extreme prejudice. Problem is, the Nightside was built on sin and corruption, and The Walking Man makes no distinction between evildoers and those simply indulging themselves. He'll leave the place a wasteland unless someone stops him, and P.I. John Taylor has been handed the job. No known magic or science can affect The Walking Man, and if John can't discover his weakness, he'll be facing the very Wrath of God.

Things were going so well for P.I. John Taylor, that it was only a matter of time before everything hit the fan. Walker, the powerful, ever-present, never-to-be-trusted agent who runs the Nightside on behalf of The Authorities, is dying. And he wants John to be his successor—a job that comes with more baggage, and more enemies, than anyone can possibly imagine.

In the secret heart of London, under the cover of endless darkness, the Nightside caters to anyone with any unusual itch that needs to be scratched. But enter at your own risk. The party animals who live here may be as inhuman as their appetites...

My name is John Taylor. The Nightside is my home. I didn't plan it that way. In fact, I once tried to get away. But I came back. And now it seems I'm settling down, with a full-time job (in addition to my work as a very private eye) as Walker—the new Voice of the Authorities in the Nightside—and a wedding in the offing.

I'm marrying the love of my life, Suzie Shooter, the Nightside's most fearsome bounty-hunter. But nothing comes easy here. Not life. Not death. And for certain, not happily-ever-after. Before I can say "I do," I have one more case to solve as a private eye—and my first assignment as Walker.

Both jobs would be a lot easier to accomplish if I weren't on the run, from friends and enemies alike. And if my bride-to-be weren't out to collect the bounty on my head...
