Synopsis by Hal Erickson
In an episode clearly inspired by Peyton Place, a former student of Jessica Fletcher (Angela Lansbury) scandalizes the town of Cabot Cove when she publishes a thinly-disguised "roman a clef" titled "The Sins of Castle Cove." The locals aren't too happy that their personalities and peccadilloes have been woven into the plotline of the book--and at least one person is willing to commit murder to suppress the novel's publication. Can it be that Jessica will find a clue to the killer within the pages of the book in question? Julie Adams, Gloria DeHaven, Kathryn Grayson and Ruth Roman return as Cabot Cove's four most garrulous gossips.
