The fourth Bernie Rhodenbarr mystery follows a pattern that will be familiar to anyone who has read even a couple of books in the series. Bernie, a neat, tidy, gentleman burglar, robs someone's home and bad things then happen that are really no fault of Bernie's. And as a result, he is forced to dig himself out of trouble.
In this case, Bernie commits a burglary assisted by his best friend, Carolyn Kaiser, a dog groomer who has a shop a couple of doors down from Bernie's used book store. Carolyn has learned that one of her clients, a very wealthy woman, will be out of town for the weekend along with her husband, leaving their house empty and ripe for the plucking. Bernie and Carolyn get into the house, thanks to Bernie's skill with a set of lock picks, only to discover that someone has beaten them to the punch. Another burglar, or burglars, have gotten into the house by dropping through a skylight and have totally trashed the place.
The other burglars, though, are obviously amateurs, and haven't been able to crack the wall safe. Bernie, who is definitely not an amateur, opens the safe and helps himself to some jewelry and a very rare coin. Bernie and Carolyn take the merchandise to one of Bernie's favorite fences. They take cash for the jewelry and leave the coin on consignment, and at that point, as usually happens in these books, everything goes off the rails. Before long, people are being killed and Bernie's nemesis, Detective Ray Kirshman, is hot on Bernie's trail. If anyone is going to save Bernie, and by extension, Carolyn, it's going to have to be Bernie.
Plot-wise, this book makes no more sense than any of the others in the series, but who cares? Bernie is a very clever, witty and resourceful guy, and the pleasure in reading these books is watching him at work and at play. As always, it's a joy to spend an evening in his company.
