Jessica Fletcher

Jessica's ancestors hailed from Kilcleer, County Cork, Ireland. She has four brothers and sisters. Two of her brothers are Marshall (Jason Evers), a doctor, and Martin. Jessica's maiden name was MacGill, inspired by the real maiden name of Angela Lansbury's mother. Before she met her husband Frank, Jessica went to Harrison College in Green Falls, New Hampshire, to become a journalist. In the episode "Alma Murder", she mentions being a member of Delta Alpha Chi sorority.

Fletcher is introduced as a widow in the first episode, her beloved husband Frank having died a couple of years before the start of the series. They had no children – Fletcher says she and Frank "weren't blessed that way" – but did spend some years raising their nephew Grady Fletcher (played by Michael Horton) after the death of his father (an unnamed brother of Frank's). For this reason, Jessica is very close with Grady. In the show's first episode, it is Grady who leads to Jessica's career as an author when he secretly sends her book The Corpse Danced at Midnight to an agent after she said she had no intention of doing so herself. Grady is a recurring character throughout the first six seasons, then makes one more appearance in season 11. Grady has several relationships that end in disappointment in some way, until the introduction of girlfriend Donna Mayberry (played by Michael Horton's wife Debbie Zipp) in the season 4 episode "Just Another Fish Story." The two marry in the season 5 episode "Something Borrowed, Something Blue." Grady and Donna later have a son, Frankie, named after Jessica's late husband.

Along with Grady, the series introduces several nephews, nieces, cousins, in-laws and other relatives or old friends who are in need of Fletcher's help, often because they or someone close to them becomes a murder suspect. One notable relation is Emma MacGill, a British cousin who is physically identical to Jessica but with a difference in accent and personality (also played by Angela Lansbury).

Fletcher lives at 698 Candlewood Lane in the town of Cabot Cove, Maine 03041. Cabot Cove is a town of 3,560 inhabitants near the ocean. Based on the number of murders that occur in a given season of the series, the town seems to have probably one of the highest murder rates of any town or city. This has even been remarked on in the series by the town sheriff, Mort Metzger. He noted in season 5, episode 21 ("Mirror Mirror On the Wall, Part 1") that this was his fifth murder in one year.

Along with being a fiction author, Fletcher has other occupations during the series. It is mentioned that she was a substitute English teacher while raising Grady. In the season 1 episode "Capitol Offense" (January 6, 1985), after the sudden death of a congressman for Maine, she is asked to temporarily assume the position as congresswoman until another politician can step in. In the season 2 episode "Jessica Behind Bars" (December 1, 1985), she teaches a creative writing class at a women's prison. In the season 8 premiere episode "Bite the Big Apple" (September 15, 1991), Jessica accepts a job as a Criminology Instructor at Manhattan University. During this time, she keeps an apartment in Manhattan at the Penfield House Apartments, located at 941 West 61st Street. On the weekends, she still regularly returns to Cabot Cove.

It is established early in the series that Jessica cannot drive. This was written into the program to facilitate the character's questioning of suspects and fellow investigators while having them drive her somewhere. Jessica Fletcher's travels as an author frequently take her to places around much of the world, giving the show writers freedom to explore characters and situations beyond rural New England. One trip takes her to Hawaii, where she shares a crossover case with private investigator Thomas Magnum (the titular star of Magnum, P.I.).

Fletcher began her career writing on an old Royal typewriter, but as her career progresses, she eventually purchases a computer running Windows 3.1. Among her friends she can count multi-millionaires who own Beech Starships as well as down-on-their-luck homeless people, moving effortlessly between the social strata. The format of the show usually has Jessica solving the mysteries within five minutes of the end of each program, unless the producers felt they could prolong the suspense across two episodes. Perhaps her most notable experience was encountering a Mr. Potts, who preferred to be called Mr. Bond—he did at least have an Aston Martin DB6, in which Jessica herself ended up racing to the rescue.

Fletcher's relationship with law-enforcement officials varies from place to place. Both the sheriffs of Cabot Cove are used to, or have resigned themselves to, having her meddle in their cases. However, most detectives and police officers do not want her anywhere near their crime scenes, until her accurate deductions persuade them to listen to what she has to say. Others are fans of her books and give her free reign. With time, she makes friends in many police departments across the United States, as well as a British police officer attached to Scotland Yard.

Fletcher is a retired teacher-turned-author of detective fiction under the name J.B. Fletcher, but constantly finds that her work and personal life overlap. In every episode, she is introduced into a situation where someone is killed shortly after her arrival. She is generally forced to solve every mystery herself in the style of one of the characters from her book, as the police prove to be incapable of doing so without her help. In fact, on at least one occasion, a law enforcement officer is actually unmasked as the killer, when John Astin appears as the villainous Sheriff Harry Pierce.

Episodes usually follow a formula. The episode opens as Fletcher arrives, either in her fictitious town of residence (Cabot Cove, Maine), or visiting elsewhere (typically in New York City or Boston) and meets several characters. These characters are usually Mrs. Fletcher's friends, family, relations, or business associates (in connection with her role as a successful author). Several of these characters are shown to have motive with respect to the potential demise of (either themselves or) one of their associates (typically an unlikeable individual). Often at least one of them is heard to make a threat against this individual, and therefore will become the principal suspect. About a third of the way through the episode, if not earlier, the likely victim is found dead. After a brief investigation, the authorities arrest the most obvious suspect, but Jessica believes that the arrested suspect (who is an amiable person, often a friend, or relative of Jessica) is innocent, and sets out to prove it.

An unrelated conversation will often suggest to Jessica the solution to the mystery, at which point she will rush off to confirm her suspicion (without telling the viewers what she has in mind and sometimes even says she thinks she knows the culprit but must still figure out how to prove it before she reveals who). The next scene will present Jessica at the place where the crime was committed, where Jessica will find one of the characters, usually alone. She enters into a conversation with this character and in a few minutes accuses him or her of being the killer, explaining how and why this person did it. The murderer first denies guilt, but Jessica describes a few clues which she observed and which the episode viewers may or may not have had an opportunity to see. Sometimes Fletcher will make up evidence which was not actually found, but the discovery of which will seem plausible to the killer. At this point, the murderer admits guilt and confesses, whereupon Jessica shakes her head sadly. Sometimes the killer will draw a weapon and attempt to kill Jessica but will be thwarted by timely police appearance from a hiding place to arrest the true killer. Once Jessica almost met a deadly fate at the hands of her own nephew, Grady, who served her a salad containing radishes without realising she is so strongly allergic to them that one mouthful could mean instant death.

The episode concludes with a final scene in which the innocent former suspects say goodbye to Jessica and thank her for the happy ending. Almost every episode then ends with a freeze frame shot of Jessica laughing or smiling. Of course, the above is only a formula and there were some unusual shows, such as the one episode where the supposedly framed suspect actually was the murderer. Then, there is another episode in which, while Grady and his heavily pregnant wife were house-sitting for Jessica, someone was murdered in the basement. Fortunately Jessica, who had been blissfully unaware of the murder for half the episode, solved the crime over the phone.
