While Miss Marple Margaret Rutherford and Mr Stringer Stringer Davis are soliciting donations for a charity, they visit Mr. Enderby Finlay Currie, a rich and eccentric recluse. He tumbles down a 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 Bud Tingwell, he is sceptical, believing that Enderby died of natural causes.Undeterred, Miss Marple eavesdrops when Enderbys family gather for the reading of the Will. There are four beneficiaries fourth cousin George Crossfield Robert Urquhart, niece Rosamund Shane Katya Douglas, nephew Hector Enderby Robert Morley and sister Cora Lanskenay. 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. Coras companion of many years, timid Miss Milchrest Flora Robson, can provide little information. ........
