The Burglar in the Library by Lawrence Block

Book 8 in the Bernie Rhodenbarr series and I look forward to reading them all. This book comes close to being too cute but Block is just too cool. PW: Bernie's sweetheart has dumped him. But although his heart is broken, he hasn't lost his love for fine books - or for an occasional discrete burglary. So Bernie takes off for a snowy winter weekend at a country inn that just happens to have a rare, signed first edition of The Big Sleep in its library. It's not long, however, before Bernie's ex-girlfriend arrives with her new husband, a body is found in the library, and the book disappears. Bernie must sort out a tricky tangle of clues if he has any hope of nabbing the priceless edition for himself. Narrator Richard Ferrone captures Bernie's cool demeanor and his flair for perfect timing.
