Agatha Christie Wiki

Murder Ahoy is the last of four Miss Marple films, made by MGM and starring Margaret Rutherford. As in the three previous films, Margaret Rutherford plays Miss Jane Marple, Bud Tingwell is (Chief) Inspector Craddock and Stringer Davis (Rutherford's real-life husband) plays Mr Stringer.

The film was made in 1964 and directed by George Pollock, with David Pursall and Jack Seddon credited with the script. The music was by Ron Goodwin.

Unlike the previous three films that were adapted from The 4.50 from Paddington (Murder, She Said - the only Miss Marple novel used), After the Funeral (a Poirot mystery, adapted for Miss Marple with the title Murder at the Gallop) and Mrs. McGinty's Dead (another Poirot novel, adapted as Murder Most Foul) - this film used an original screenplay that was not based on any of Christie's stories.

The film does, however, employ elements of the Miss Marple story They Do It With Mirrors. Specifically, the Battledorn is a training ship for teenage boys with criminal tendencies, who are supposedly being set on the straight and narrow path - when, in fact, one of the members of the crew is training them for careers in housebreaking. In the same way, Lewis Serrocold in the "They Do It with Mirrors" trained some of his boys and planted them into financial positions where they helped him to embezzle funds for the institution. However, except for Miss Marple from the novel, none of the characters have been borrowed over.

There is also an entirely tongue-in-cheek reference to The Mousetrap, the Christie play that has been running continuously on the West End since 1952. Audiences who see The Mousetrap are asked to keep the ending a secret, so it is amusing when Margaret Rutherford's Miss Marple says that she's reading a "rattling-good detective yarn" and "I hope I won't be giving too much away if I say the answer is a mousetrap!" She then notes that she'll "say no more - otherwise, I'll spoil it for you!"

The action takes places mainly on board an old wooden-walled battleship, HMS Battledore, which has been purchased by a Trust for the rehabilitation of young criminals, and intended by the founder to put backbone into young jellyfish.

Shortly after joining the board of management of the Trust, Miss Marple witnesses the sudden death of a fellow trustee, who has just returned from a surprise visit to the ship. She manages to obtain a small sample of his snuff, which is found to have been poisoned. She visits the ship, much to the distress of the Captain and crew, who do not like visitors.

Her first night on board, one of the officers is murdered - run through with a sword and then hanged. As the police investigation proceeds, the assistant matron is killed, apparently by a poisoned mousetrap.

Miss Marple sets a trap by pretending to be left alone at night on the deserted ship, but secretly smuggling in Chief Inspector Craddock and another policeman. She finds a large sum of money hidden in a cannon which turns out to have been embezzled by Commander Breeze-Connington, money he feels is owed to him after he was passed over for promotion. It was protected by a poisoned mousetrap. After the commander appears and admits all, Miss Marple calls out to the police inspector to make the arrest, but he and his colleague have accidentally been locked in and cannot help. Miss Marple and Breeze-Connington engage in a ferocious fencing match, before she is disarmed. Just as he is about to administer the coup de grace, however, he is hit over the head from behind by Mr. Stringer who, alarmed at what might be going on, had secretly rowed out in the dark.

The finale is a court martial for Captain Rhumstone who has been accused of mismanagement. Seeing the hilt of the sword toward him, he mistakenly thinks he has been found guilty but is corrected by Miss Marple. Nevertheless, he announces that he must resign just the same because Matron wants to get married, and so does he. He fully realises that it is a golden rule of the trust that there should be no hanky-panky between the sexes on board ship, so he makes his farewell and turns to go. Miss Marple stops him, saying, "I think I speak for my fellow trustees when I say that golden rule is hereby rescinded. You're a fine sea dog captain, but it seems to me the Battledore could do with a woman's hand at the helm. As Matron and the Captain wave good-bye to Miss Marple, he says, "As soon as I saw her, I said, 'What an old darling'!"

  2. Some internet resources such as IMDB list this, stating that it is Miss Marple's Cottage. But there is some doubt about this as the same resources also list Misbourne Cottage at Denham as Miss Marple's Cottage, and the external views are quite clearly the cottage at Denham. Margaret Rutherford herself lived at Gerard's Cross and it is possible that her house or some other house there was used for the interiors.
