When Cabot Cove resident Beverly Garrett is electrocuted in her own bathtub in a locked bathroom, Sheriff Amos Tupper (Tom Bosley) is willing to write the tragedy off as an accident; Tupper, you see, is thinking about retirement, and has already hand-picked his successor. But Jessica (Angela Lansbury) can't shake the belief that Beverly was murdered, prompting the long-suffering Tupper to dare Jessica to prove it! Adding to the intrigue is a controversial land sale, a vicious poison-pen campaign that has spread throughout town, and Jessica's mounting frustration over playing hostess to a visiting travel writer. ~ Hal Erickson, Rovi
