Miss Marple and Mr. Stringer are witnesses to the death by heart attack of elderly, rich Mr. Enderby. Yet they have their doubts about what happened. The police don't believe them, thus leading Miss Marple to yet again investigate by herself.
Murder at the Gallop (1963) is the second of four Miss Marple films made by Metro-Goldwyn-Mayer. It was based on the 1953 novel After the Funeral by Agatha Christie, with Margaret Rutherford as Miss Jane Marple, Charles "Bud" Tingwell as Inspector Craddock and Stringer Davis as Jane Marple's friend Mr Stringer returning from the previous film.
