Night Town by Timothy Hallinan

An empty, haunted old house even Junior Bender is afraid of? I'm in.

In this, the seventh book of the series, the burglar with a heart takes a job he knows will be trouble. They pay is too high, way too high, but if he's going to make bank to help his ladylove get her kid from the ex, he's going to have to shake off the heeby-jeebies and find a stupid doll in a stinky, vacant house about to be destroyed.

But Junior's a book nerd and historian extraordinaire, so when the house gets to him he embarks on a reference and genealogy project to figure out the backstory. Meanwhile, the job's a big damn mess that's been double-booked and double-crossed, so Junior's on high alert to tails, shooters, and creeps. Which means he's not going home and instead bunking in another crazy, seedy hotel. These hotels have become a character in their own right in the series.

I really like this character, and I especially liked the Grey Gardens style history he digs up this time on the funky house and the family who built it.
