Iedereen gaat ervan uit dat de rijke Richard Abernethie een natuurlijke dood stierf. Alleen zijn zuster houdt vol dat hij vermoord werd. De notaris van de familie besluit de erfgenamen eens grondig onder de loep te nemen en zijn vriendin Miss Marple helpt hem daarbij.
Nee, helaas is Murder at the Gallop nog niet beschikbaar op Netflix in Nederland.
