Enjoying Sunday breakfast, the three are interrupted when the local constable requests Japp's help. Walter Protheroe, the reclusive owner of a local large mansion, was found dead in his dilapidated house, supposedly by suicide. Or was it? The three go to Leigh House as requested and meet Dr. Giles who was called in by Miss Clegg, the housekeeper. She was unable to raise her master, Walter Protheroe, in his bedroom, r could Giles. Constable Pollard arrived at that moment and he and the doctor broke down the oak door. Inside they found Protheroe, shot through the head and his pistol clasped in his right hand.

Dame Agatha Mary Clarissa Christie, DBE (nee Miller; 15 September 1890 - 12 January 1976) was an English crime novelist, short story writer, and playwright. She also wrote six romances under the name Mary Westmacott, but she is best known for the 66 detective novels and 14 short story collections she wrote under her own name, most of which revolve around the investigations of such characters as Hercule Poirot, Miss Jane Marple, Mr Satterthwaite, and Tommy and Tuppence. She also wrote the world's longest-running play, The Mousetrap. Born into a wealthy upper-middle-class family in Torquay, Devon, Christie served in a hospital during the First World War, before marrying and starting a family in London. She was initially unsuccessful at getting her work published; but in 1920 The Bodley Head press published her novel The Mysterious Affair at Styles, featuring the character of Poirot. This launched her literary career. The Guinness Book of World Records lists Christie as the best-selling novelist of all time. Her novels have sold roughly 2 billion copies
