The cat who swallowed more than a canary...

A lifetime of craving more cuddly companionship than her hectoring mother has led fortyish Bettina Bilby to board her neighbors' felines for a long holiday weekend: an expectant tabby, a pampered blue-eyed Balinese, a depressed ginger Persian with a cod-liver-oil addiction, and Adolf, an imperious mouser with a patchwork face.

But a freak storm sets the pigeon among the cats-- a carrier bird downed on the doorstep with a tiny load of large flawless diamonds. And Bettina's dilemma escalates, as Adolf gobbles up one of the gems and a succession of elegant but shifty strangers prowl the gardens, offending the cats, and bringing in their wake back-door bloodshed and murder.
