Synopsis by Hal Erickson
A motion picture crew descends upon Cabot Cove to film a historical documentary. In the course of production, the crew unearths an old document signed by George Washington, which claims that the town's most venerated Revolutionary War hero, Joshua Peabody, was actually a traitorous scoundrel. Evidently someone isn't pleased about having his or her illusions shattered: shortly after the document appears, the film's director is murdered. Now it is up to Jessica (Angela Lansbury) to burrow through the multitude of likely suspects.
