This article: While Miss Marple and Mr Stringer are soliciting donations for a charity ("The Reformed Criminals Assistance League"), they visit Mr. Enderby, a rich and eccentric recluse. He tumbles down the long entrance staircase, apparently the victim of a fatal heart attack. Knowing that Enderby had a pathological fear of cats, Miss Marple becomes suspicious when she finds one in the house. She also finds a piece of mud bearing the print of a riding boot, but when she goes to Inspector Craddock, he is sceptical, believing that Enderby died of natural causes.
Undeterred, Miss Marple eavesdrops when Enderby's family gather for the reading of the Will. There are four beneficiaries: fourth cousin George Crossfield, niece Rosamund Shane, nephew Hector Enderby and sister Cora Lansquenet. Each receives an equal share of the estate. Cora declares that she believes Enderby was murdered. The next day, when Miss Marple goes to see her, she finds Cora dead, stabbed in the back with a hatpin. Cora's companion of many years, timid Miss Milchrest, can provide little information.
Miss Marple decides to take a "holiday" at the Gallop Hotel/riding school, as it is run by Hector Enderby and the other two surviving heirs and Miss Milchrest are staying there. When Inspector Craddock questions them and Rosamund Shane's spendthrift husband Michael, none of them can produce a satisfactory alibi for the time of Cora Lansquenet's death. contains an answer for the question: What heirs are staying at the Gallop Hotel/riding school run by Hector?, what is it ?
