During a political fundraiser in San Francisco, a necklace is stolen (apparently) and a man murdered (positively!) The dead man was a powerful publisher with senatorial ambitions, whose body was found on the balcony of the hotel room occupied by Jessica Fletcher (Angela Lansbury); the necklace belonged to the decedent's wife. Suspecting that the man accused of the crime--a professional jewel thief who'd hidden himself in Jessica's room--is not guilty, Jessica sets about to crack the case. Keith Michell makes his first series appearance as the delightfully larcenous Dennis Stanton.
