In the climax of the 1963 film Murder at the Gallop, the main character, Miss Jane Marple (played by Margaret Rutherford), goes to a bedroom at "The Gallop," the combined hotel and riding school where the suspects are staying.
Here are the specific details regarding why she goes there and what happens:
Miss Marple determines that the killer is Gregory Caswell. She realizes the motive involves the high value of a painting that was dismissed as worthless, and she knows the killer must silence her to protect their inheritance.
To draw the killer out, Miss Marple stages an elaborate ruse. During a social dance at the hotel (where she famously performs an energetic version of a dance called the "6.20 Soul"), she fakes a heart attack (or a physical collapse) to appear vulnerable and incapacitated.
The underlying reason she was in danger in the first place—and why she had to set the trap—was her discovery that the deceased Mr. Enderby owned a very valuable "Old Master" painting that had been disguised as a cheap, modern piece. Caswell had killed Enderby (by frightening him with a cat, knowing his phobia) to secure the estate and the hidden treasure. Miss Marple’s trip to the bedroom was the final "gambit" to prove his guilt.
The AI completely misidentified the killer as 'Gregory Caswell' (a non-existent character) instead of Miss Milchrest.
The AI hallucinated the dance name '6.20 Soul' instead of the famous 'Twist' scene.
The AI attributed ownership of the painting to Mr. Enderby, whereas it was his sister Cora's possession that drove the second murder.
In the climax of Murder at the Gallop (1963), Miss Marple (Margaret Rutherford) fakes a heart attack while dancing the Twist with Mr. Stringer at the hotel dance. She is taken to a bedroom at 'The Gallop' to rest. The killer, Miss Milchrest (Flora Robson), enters the room to silence her (often associated with a hatpin or physical attack). Miss Marple reveals she is awake, and the police (Inspector Craddock) emerge from hiding to arrest Milchrest. The motive was a valuable painting owned by the late Cora Lansquenet, which Milchrest wanted.
