The opening episode of Murder She Wrote's second season marks the first occasion in which matronly mystery writer and amateur sleuth Jessica Fletcher (Angela Lansbury) assumes a different identity in the cause of justice. Summoned to a Caribbean resort by a desperate letter from her old friend Antoinette Farnsworth (Reggie Savage), Jessica arrives to find that Antoinette has been murdered. To ferret out the guilty party, who has already been pinpointed as a jewel thief, our heroine poses as a very wealthy--and very reclusive--widow. Len Cariou, who previously costarred with Angela Lansbury in the hit Broadway musical "Sweeney Todd", makes his first appearance as redoubtable British secret agent Michael Haggerty.

Over the protests of several local residents, shady tycoon Henderson Wheatley (John Ericson) intends to build a high-rise hotel in Cabot Cove. During excavation, a set of bones comes to surface, supposedly belonging to Revolutionary war hero Joshua Peabody. Almost immediately, those who oppose the hotel insist that the land be consecrated as a national monument, while others insist that those aren't Peabody's bones at all. Whatever the case, it soon develops that the centuries-old remains are those of a murder victim--and before long, Wheatley himself is murdered. William Windom makes his first series appearance as Dr. Seth Hazlitt, an old friend of heroine Jessica Fletcher (Angela Lansbury)...and a likely suspect in the killing.

Up-and-coming actress Nita Cochran (Alice Krige), who happens to be the niece of Jessica Fletcher (Angela Lansbury), lands a plum role on a popular TV soap opera. Nita has been cast as a serial murderer--a fact that proves most unfortunate when an actual murder occurs at the TV studio. The victim was Nita's boss, who may or may not have been planning to abruptly write her off the show. . .but it soon develops that Nita was only one of several people with a strong motive. This episode represents the final TV appearance of Lloyd Nolan, whose well-known difficulty in memorizing lines is cleverly woven into the final scene.

Jessica (Angela Lansbury arrives at the campus of Crenshaw University to receive an honorary degree. Among the faculty members is Professor Joselyn Clover (Polly Bergen), whose daughter Daphne (Mary Kate McGeehan) has penned a notoriously lurid best-selling novel. When the campus "stud" is murdered, both Joselyn and Daphne are suspected--whereupon both confess to the crime in hopes of protecting one another. Figuring that someone else is the guilty party, Jessica offers her services to the local police chief (Jack Kehoe), who unlike our heroine has never handled a homicide case in his life!

Angela Lansbury plays a dual role in this episode, as Maine-based mystery writer Jessica Fletcher and as Jessica's flamboyant cousin, British music-hall headliner Emma MacGill. Arriving in London to attend Emma's funeral, Jessica is surprised to learn that her cousin is still alive. Having survived one murder attempt, Emma has decided to "play dead" until she can find out why someone wants to kill her--allowing Jessica to join in on the sleuthing, of course. The highlight of this episode is Emma's performance of the sentimental ditty "Goodbye, Little Yellow Bird"--which Angela Lansbury had previously sung to great acclaim in the 1945 theatrical feature The Picture of Dorian Gray.

Ann Blyth guest stars as Franchesca Lodge, an old friend of mystery writer Jessica Fletcher (Angela Lansbury). Recently married to a much-younger man named Scott (Stacey Nelkin), Franchesca has been terrorized of late by what seems to be the ghost of her first husband. Since Franchesca has had a history of mental problems and profound lapses of memory, the authorities doubt her "haunting" story--and when her second husband is murdered, those same authorities jump to the conclusion that Franchesca has gone completely insane and committed murder. Jessica of course refuses to believe this, and thus does the sleuthing commence!

Retreating to a placid Maine lake resort in order to finish her latest novel without distractions, Jessica (Angela Lansbury) decides to go birdwatching one fine morning. During this pursuit, Jessica witnesses what seems to be a struggle between a man and a woman in a boat on the lake, ending with the woman falling overboard. The man is accused of murder, but Jessica believes that the victim was not pushed in the water but instead jumped on her own accord--and the mystery deepens when it turns out that the drowned woman was a champion swimmer!

Jessica (Angela Lansbury) pays a visit her niece Tracey (Linda Grovenor), an up-and-coming jockey. After winning a race, Tracey has a confrontation with the horse's owner, indicating that she was supposed to have thrown the race. Not long after, the owner turns up murdered--and Tracey is the prime suspect. Naturally, Jessica isn't about to let her niece take the rap for a crime she didn't commit...and besides, she has a pretty good idea "whodunit" (especially since the revelation of the actual culprit follows the most reliable of the Murder She Wrote guidelines!)

The scene is the West Barrington Institute for Women, where warden Elizabeth Gates (Vera Miles) invites Jessica (Angela Lansbury) to lecture on creative writing. Of course, wherever Jessica goes, murder follows, and this time the victim is the prison's doctor Irene Matthews (Janet McLachlan). Believing that an innocent woman has been accused of the crime, the inmates stage a riot, taking several hostages--including Jessica--in the process. In order to save Warden Gates from being killed in the mistaken belief that she is the "real" culprit, Jessica races against time to solve the murder herself. This is the only Murder She Wrote episode to boast an all-female cast.

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.
