When the saintly Tabby Cullman turns up dead under some holly shrubs, there are no indications that it is anything but a tragedy. The only person who thinks otherwise is Harry Pierson, Tabby’s assistant, who insists to anyone who will listen that Tabby was murdered and he knows who did it. While Leo is forced to look into all the claims coming in, Penelope finds herself drawn into helping Harry when the police fail to take Harry’s ravings seriously. Things get even more complicated for Penelope when Mabel ends up in the investigation as well. Mabel might be a lot of things, but Penelope cannot see the woman as a killer. Things would be a lot simpler if Penelope’s Cousin Bradley were not in the way, and if Leo would stop treating Penelope like she was going to break any moment. Can Penelope figure out the mystery of Tabby’s death and save Fall Creek’s holiday season?
