The Burglar in the Rye by Lawrence Block

Very good and funny, want to read another in the Bernie Rhodenbarr series. PW: In this diverting caper, full-time bookstore owner and part-time burglar Bernie tries to do the right thing for a new friend, only to find himself accused of some terrible wrongs. All Bernie plans to do is steal some letters. A New York City literary agent is auctioning off her personal correspondence with enigmatic writer Gully Fairborn. Gully's attractive ex-girlfriend has asked Bernie to swipe the letters so she can return them to her old heartthrob. But when Bernie breaks in, the letters are missing, and the literary agent is in bed with no hope of waking up. With the police watching him very closely, Bernie relies on jiggers of rye and Caroline, his lesbian best friend, to sharpen his deductive skills and find the killer. Narrator Richard Ferrone expertly guides you on a laugh-filled journey through the twists and turns of the clever plot.
