A Fool There Was. Hank Mossberg, Private Ogre, #4

Sedgwick's one of a kind fantasy series continues, and this time Hank Mossberg is taking a backseat. Prepare to be treated to an entirely different perspective on life in the gritty fantasy setting of San Francisco's undercity:Goblin P. I. Sam Snyvvle may be crude, cynical, and vulgar, but one thing he's not is stupid. When a gorgeous dryad offers Sam a king's ransom to retrieve her stolen diamond, he knows the whole thing smells like a setup.
Unfortunately, there are two things that Sam can never pass up: a gorgeous dame, and a truckload of money. Besides, if things don't work out with the girl, Sam knows he can always pilfer the diamond for himself. Snyvvle sets out to find the missing gem, but immediately ends up in hot water. He's trapped in a room with a dead mob boss, an empty safe, and the police banging down the door. Sam knows he looks guilty as sin, so he does what any sensible goblin would do.
He goes on the run. Now, Sam is in a race to locate the missing diamond before the cops catch him or the mobsters kill him. Fortunately, Sam knows the dark, seedy streets of the undercity like the back of his hand, and he swears that when he finds the people who framed him, they're going to regret it. That is, if the cops, the mob, and his arch-nemesis Hank Mossberg don't catch him first!
