Murder At The Gallop

This is one of a series of competent murder mysteries directed by George Pollock based on the Agatha Christie character, Miss Marple. Margaret Rutherford stars as the grey-haired, wily sleuth who will not give up until all the pieces of a puzzle have been neatly put in place. This time around, an old village recluse is found dead and everyone except Miss Marple believes he had a heart attack. She is suspicious because four members of the dead man's family stand to benefit from his death, especially when a highly valuable painting is added into the kitty. As she follows her instincts and logic, a few more murders eliminate the same number of suspects, and Miss Marple is compelled to lend haste to her investigation before someone else turns up dead.
