Agatha Christie's Devon runs from Burgh Island, the model for Soldier Island in And Then There Were None, to Churston, Dittisham and her own Greenway estate on the River Dart.
The route follows five stops through The A.B.C. Murders, And Then There Were None, Five Little Pigs, Towards Zero and Dead Man's Folly. Two stops share the Greenway pin, and Nasse House is fictional.
Murder on the Orient Express runs from Aleppo through Istanbul and Belgrade to a snowdrift near Vinkovci. Poirot's train is stuck there with a murdered man aboard and the killer still on it.
The route follows the story from Aleppo station through Istanbul, where Poirot gets his telegram and his berth, and Belgrade to the snowdrift near Vinkovci. It ends with the 1932 kidnapping that gave Christie her plot. Most pins are indicative: the novel names few exact places.
Agatha Christie's 1937 mystery puts Hercule Poirot on holiday in Aswan, waiting to board the Nile steamer Karnak. Among his fellow passengers are a jilted woman stalking her ex-fiancé's honeymoon, her former friend the heiress, and a boulder that comes uncomfortably close to the bride.
The route follows the steamer from Aswan to Wadi Halfa and ends at Karnak, where the 1978 film moves the falling stone. The novel itself puts that scene at Abu Simbel.
