Bernie Rhodenbarr is back and he's after the prized coin collection of one Herb Colcannon and he has the inside information to help him....or so he thinks! But the Colcannon house is a set-up and he's not the first to think of the heist. What's more the collection consists of just one coin...worth over $250,000...so who is Bernie going to sell it to and how is he going to get away with it?
