Dead Men's Boots — Mike Carey

Castor's fellow exorcist John Gittings made several calls asking for help before his demise, and if Castor had answered them, his friend might still be alive. So when a smooth-talking lawyer claims the corpse, Castor owes it to John's unhappy ghost to step in. But life is rarely that simple for Felix Castor.

He's also getting involved with a brutal murder case that bears all the hallmarks of a long-dead American serial killer...while fighting for the life -- if not the soul -- of his demon-possessed friend, Rafi. To top it off, Castor can't shake the feeling that his three problems are related. Turning to succubus Juliet and zombie data-fence Nicky for aid, this overworked ghost hunter may fit the pieces together before someone rips his throat out. Or not.
