few human weaknesses. The only mistakes she makes within the series are a typing error during the events of Hickory Dickory Dock and the mis-mailing of an electricity bill, although she was worried about strange events surrounding her sister at the time. Poirot described her as being "Unbelievably ugly and incredibly efficient. Anything that she mentioned as worth consideration usually was worth consideration." She is an expert on nearly everything and plans to create the perfect filing system. She also worked for the government statistician-turned-philanthropist Parker Pyne. Whether this was during one of Poirot's numerous retirements or before she entered his employment is unknown. In The Agatha Christie Hour, she was portrayed by Angela Easterling, while in Agatha Christie's Poirot she was portrayed by Pauline Moran. On a number of occasions, she joins Poirot in his inquiries or seeks out answers alone at his request. Chief Inspector James Harold Japp Japp is a Scotland Yard Inspector and appears in many of the stories trying to solve cases that Poirot is working on. Japp is outgoing, loud, and sometimes inconsiderate by nature, and his relationship with the refined Belgian is one of the stranger aspects of Poirot's world. He first met Poirot in Belgium in 1904, during the Abercrombie Forgery. Later that year they joined forces again to hunt down a criminal known as Baron Altara. They also meet in England where Poirot often helps Japp and lets him take credit in return for special favours. These favours usually entail Poirot being supplied with other interesting cases. In Agatha Christie's Poirot, Japp was portrayed by Philip Jackson. In the film, Thirteen at Dinner (1985), adapted from Lord Edgware Dies, the role of Japp was taken by the actor David Suchet, who would later star as Poirot in the ITV adaptations. Major novels The Poirot books take readers through the whole of his life in England, from the first book (The Mysterious Affair at Styles), where he is a refugee staying at Styles, to the last Poirot book (Curtain), where he visits Styles before his death. In between, Poirot solves cases outside England as well, including his most famous case, Murder on the Orient Express (1934). Hercule Poirot became famous in 1926 with the publication of The Murder of Roger Ackroyd, whose surprising solution proved controversial. The novel is still among the most famous of all detective novels: Edmund Wilson alludes to
