Although the evidence appears to be overwhelming in the strangulation murder of a blackmailer, Miss Jane Marple's (Dame Margaret Rutherford's) sole "not guilty" vote hangs the jury 11-1. She becomes convinced that the real murderer is a member of a local theatrical troupe, so she joins them in order to gather information. The clues lead back many years to a single disastrously unsuccessful 1951 performance of a dreadful play written by the group's hammy director, H. Driffold Cosgood (Ron Moody). Although at that time, several of the current cast members were only children, more murders follow before Miss Marple ultimately exposes the killer.

After the death of her famous opera-singing aunt, Paula Alquist (

Six months after the disappearance of Tuscarora, PA businessman Tom Gruneman, his boss, Peter Cable, and his wife, Holly Gruneman, hire Tom's friend, private detective John Klute to find out what happened to Tom, as the police have been unable to do so, and despite John having no expertise in missing persons cases. The only lead is a typewritten obscene letter Tom purportedly wrote to Manhattan actress/model/call girl Bree Daniel, who admits to having received such letters from someone, and since having received several mysterious telephone calls as well. The suggestion/belief is that Tom was one of Bree's past johns, although she has no recollection of him when shown his photograph. Bree's tricking is both a compulsion and a financial need. In their initial encounters, John and Bree do whatever they can to exert their psychological dominance over the other, especially as Bree initially refused to even speak to him. Despite their less than friendly start, they embark on a personal relationship based on emotional need, but it is a relationship Bree tries to sabotage because of those same issues which causes her to turn tricks. As they follow the leads through Bree's call girl world, they know they're getting close to finding the truth when someone continues to torment Bree. They believe the key to Tom's disappearance is a violent john who tried to kill her a few years earlier when Tom disappeared but who she doesn't remember. The questions become whether John and Bree can discover his identity and stop him before he tries to kill Bree again, and whether there is a future for them together.

There are eight guests and two servants there for the weekend, but one by one, they are being knocked off according to the poem of "Ten Little Indians".

Despite not knowing him, the world's most famous detectives can't pass up the offer of a "dinner and murder" invitation from wealthy Lionel Twain (Truman Capote). Each has no idea until their arrival at Two Two Twain who else will be in attendance. Those detectives are: amateur sleuths and New York City socialites Dick (David Niven) and Dora Charleston (Dame Maggie Smith), accompanied by their pet terrier, Myron; Belgian detective Monsieur Milo Perrier (James Coco), accompanied by his chauffeur, Marcel (James Cromwell); Shanghainese Inspector Sidney Wang (Peter Sellers), accompanied by his Japanese adopted son, Willie Wang (Richard Narita); frumpish Brit Miss Jessica Marbles (Elsa Lanchester), accompanied by her invalid nurse, Miss Withers (Estelle Winwood); and San Francisco gumshoe Sam Diamond (Peter Falk), accompanied by his femme fatale sidekick, Tess Skeffington (Eileen Brennan). The dinner part of the invitation runs into problems due to the non-communication between Twain's blind butler, Jamesir Bensonmum (Sir Alec Guinness), and Twain's new deaf-mute and non-Anglophone cook, Yetta (Nancy Walker). On the murder side, the guests initially believe Twain will try to kill each of them. However, Twain eventually announces his rationale for the gathering: that one of the people at the dinner table will be murdered before midnight, and that Twain will consider himself the greatest detective if his guests, who are now trapped in the house until dawn, cannot figure out who committed the murder, that person also at the dinner table. If one does figure out who committed the crime, he or she will be the recipient of one million dollars and the exclusive rights to the story. So the guests anxiously await the stroke of midnight, with those still alive after that time trying to figure out motive and the opportunity to murder before the rise of dawn, and before the murderer has the opportunity to strike again on one or all of them.

Sherlock Holmes investigates London's most infamous case, Jack the Ripper. As he investigates, he finds that the Ripper has friends in high places.

Famed American playwright Phillip Hannon is in London making revisions to his play currently running in the West End. He is doing this mundane work rather than write a new play since he has retreated from life following the recent and permanent loss of his sight. That retreat from life includes breaking off his engagement to his former secretary, Jean Lennox, who still loves him. One evening at his local pub, he overhears a conversation between a man and a woman that he knows involves criminal activity, what he surmises to be the kidnapping plot of a child in exactly one week's time. The local police patronizingly dismiss his report as the overactive imagination of a blind writer. With Jean and his faithful manservant Bob Matthews by his side - the former with some reluctance on Phil's part - Phil goes on a search to uncover the plot using what little pieces of information he has at hand, which includes the man's name being Evans, the woman, who is involved under duress, working as a nanny for a family whose head is formally a lady, that lady having attended a concert that evening, the family living along a certain bus route, and the nanny herself wearing an expensive perfume well beyond her means. His physical disability is an obvious disadvantage. But what may be working to Phil's advantage is his keen sense of dialogue and its subtext in deciphering the conversation, using his other senses which people with sight take for granted, and people, including the criminals, underestimating him because he's blind.
