Inspector Ames is called to the house of the wealthy widow Mrs. Greer who is an old friend of Colonel March. She had once named a rose after him, a fact with which Ames later teases March. Upon arriving at the house, Ames overhears a heated argument between Mrs. Greer and her daughter-in- law, Johannna, also a widow. Mrs. Greer called the police because, according to the vet, her dog Dobie had been poisoned by arsenic (the dog survived). Ames gives her very short shrift indeed and storms put of the house. Mrs. Greer suspects one of the employees of the posh beauty salon she owns is dipping into the till and she is harassing another of the employees. Pretty clearly all three of the employees at the salon hate her as does Johanna. When Mrs. Greer is murdered in the salon, there are plenty of suspects. The only person who seems to care that she's dead is her housekeeper Mary. This episode has a good gimmick which, of course, March figures out. A pretty good episode but not one of the best.
