Jessica Fletcher (Angela Lansbury) finds herself facing a lawsuit--and a possible prison term--as Murder She Wrote launches its seventh season. The litigant is the daughter of a man whom Jessica sent to prison, and who subsequently died in a botched escape attempt. As out heroine fends off charges of perjury and bribery, the plot thickens with the murder of an eyewitness to the original crime. The suspects are certainly a motley crew this time, ranging from a sleazy lawyer to the wife of a temperamental chef!

Saddled with a broken arm, Jessica (Angela Lansbury) hires a temporary typist named Melissa (Lise Cutter) to help her meet a deadline. "Dead" is right: It turns out that Melissa is a virtual mystery novel all in herself, as proven when she inveigles a moonstruck cub reporter into helping her tamper with some evidence at a murder scene. The victim is Melissa's loutish husband (Cliff Potts), whose body is moved to his own lumberyard as an efforts to keep Melissa from being implicated--but things don't quite work out as planned, obliging Jessica to play detective yet once more.

This is one of several seventh-season Murder She Wrote episodes introduced by Jessica Fletcher (Angela Lansbury) but starring Dennis Stanton (Keith Michell), an ex-jewel thief turned insurance investigator. An unscrupulous divorce lawyer is killed, and the suspect list includes (a) the lawyer's husband, (b) the lawyer's secretary and (c) the lawyer's ex-wife--not to mention another lawyer who used to be a cop. Stanton investigates this perplexing case with the aid of the redoubtable Rhoda Markowitz (Hallie Todd).

Jessica (Angela Lansbury) agrees to finish a book that was inaugurated by recently deceased Pulitzer-winning journalist Daniel Hannigan (Van Johnson). The book was intended to reopen a 16-year-old murder case, and to prove that the man convicted of murdering one Lydia Thurlow was really innocent. Following the trail of clues left behind by Hannigan, Jessica comes across a full complement of suspects, among them Lydia's brother and sister-in-law (Raphael Sbrage, Cynthia Harris), and the police commissioner (Bradford Dillman) originally assigned to the case.

Brenda Vaccaro is featured as Sheila Kowalski Finley, a freewheeling society matron who has the cute habit of taking jewelry that doesn't belong to her. When her husband's chauffeur is murdered during a political fundraiser, Sheila is among the suspects, if for no other reason than she was carrying on an affair with the dead man. Inasmuch as she is an old friend of Sheila, Jessica (Angela Lansbury) sets herself to finding out who really "dun it"--and the suspects this time include the chaffeur's OTHER clandestine lover! (Be assured that Sheila's kleptomania will be deftly worked into the plotline).

The ladies of Cabot Cove are enchanted by a newcomer to the community, handsome gym instructor Wayne Bennett (Jason Beghe). Especially fascinated by Bennett is Eve Simpson (Julie Adams), who naturally is an old friend of Jessica Fletcher (Angela Lansbury). When Bennett's onetime partner, con artist Fred Kepper (Hugh O'Brien), turns up dead in Eve's bedroom, Jessica can't bring herself to believe that her friend had anything to do with this awkward turn of events--and as always, Jessica knows best.

For the first time in Murder She Wrote history, a murderer whom Jessica Fletcher (Angela Lansbury) had turned over to the police in a previous episode makes a comeback appearance. The man in question is Jessica's first publisher (and erstwhile sweetheart!) Preston Giles (Arthur Hill), who had been exposed as the killer in the series' very first episode. Released on parole, Preston goes back to work at a high-level corporation. Although Jessica had hoped to avoid a reunion with Giles, she is unable to do so when he is accused of murdering his company's duplicitous financial controller.

This is one of several seventh-season Murder She Wrote episodes introduced by Jessica Fletcher (Angela Lansbury) but starring Dennis Stanton (Keith Michell), a jewel thief turned insurance investigator. Dennis is sucked into the story when a disreputable former associate shows up in San Francisco, possessing what he claims to be a rare original manuscript by Samuel Clemens, aka Mark Twain. In rapid succession, the manuscript is proven to be forgery by a book expert, the manuscript is torched, and the expert is murdered. As Stanton tries to prove that his old "pal" is innocent, his trail is dogged by the ineluctable Rhoda Markowitz (Hallie Todd) and the irascible police lieutenant Perry Catalano (Ken Swofford).

While visiting a friend in Nashville, Jessica (Angela Lansbury) comes face to face with Bobby Diamond (Jimmy Dean), a popular country singer with more than a few of the requisite skeletons in his closet. A maelstrom of greed and philandering yields a murder, whereupon Jessica tries to find out who among Bobby's many enemies hated him enough to kill him. Featured in the cast is C&W entrepreneur-club owner Mickey Gilley, and "Carol Brady" herself, Florence Henderson.

This is one of several seventh-season Murder She Wrote episodes introduced by Jessica Fletcher (Angela Lansbury) but starring Dennis Stanton (Keith Michell), a jewel thief turned insurance investigator. Stanton's latest assignment is to investigate the suspicious events surrounding a fire that destroyed the hands of famous concert pianist Vaclav Maryska (Ricardo Montalban). The intrigue reaches a crescendo when Maryska's wife Milena (Patricia Neal) is murdered, with a veritable orchestra of suspects at Stanton's disposal. As usual, Stanton is more or less assisted by ditzy Rhoda Markowitz (Hallie Todd) and by flustered Lt. Catalano (Ken Swofford).
