Along with her friends Amos (Tom Bosley) and Seth (William Windom), Jessica (Angela Lansbury) decides to sample the cooking at Cabot Cove's newest tourist attraction, the Joshua Peabody Inn. Casting a pall over the evening is a batch of spoiled strawberry preserves, causing several patrons to become seriously ill. When one of these patrons subsequently dies, Jessica begins to suspect that the "accidental" poisoning was deliberately contrived. ~ Hal Erickson, All Movie Guide
