Dan Shamble, Zombie P.I. ZOMNIBUS

Back from the Dead,
Back on the Case
Meet Dan Chambeaux-a.k.a. Dan Shamble-zombie detective, a persistent hardboiled gumshoe (or maybe that's something more sinister on the bottom of his shoe…)
Even being murdered doesn't keep a good detective down, and in the Unnatural Quarter-inhabited by ghosts, vampires, werewolves, mummies, and all sorts of creatures that go bump (or thud!) in the night-a zombie P.I. fits right in. Dan Shamble solves a string of madcap cases with his ghost girlfriend Sheyenne, his Best Human Friend Officer Toby McGoohan, and his firebrand lawyer partner Robin Deyer.
And first on the list: finding out who murdered him.
This Zomnibus contains the complete first Dan Shamble novel, Death Warmed Over, plus the seven individual cases showcased in the collection Working Stiff, together in one volume. It's a perfect way to dig up the dirt on a lot of things that would rather stay buried.
Dan Shamble puts the PI in RIP.
