It's late spring and young artist Gerry Coneybear and her twenty cats are thrilled to finally be able to get out of the house and into the garden surrounding her 200-year-old house on the Ottawa River. But Gerry is having a time keeping her curious cats in their own yard, safe from the new neighbours' large dog. Her neighbours' marriage isn't quite what it should be, and when the philandering husband is murdered, the wife is the obvious suspect. Or ought to be. As events unfold next door, Gerry watches from her garden, where she picks rhubarb, weeds, and plants her flowers, catnip and herbs, all supervised by her cats and her friend and part-time housekeeper Prudence. A terrible car crash, an eccentric train engineer (and his equally eccentric wife), and a midnight visit to the house next door all contribute to this cozy mystery coming out all right in the end. And there's jam-making. And ghosts.
