Murder in the Calais Coach [aka Murder on the Orient Express]

Agatha' Christie's novel featuring Hercule Piorot, Murder on the Orient Express, was first published by Collins Crime Club in the United Kingdom in 1934. Later that year the book hit American shores as Murder in the Calais Coach. The American title was chosen to avoid public confusion with another "double-titled" book, Graham Greene's Stamboul Train, published in the USA as Orient Express. This title that was eventually phased out after Dodd & Mead's original hardcover editions and a paperback edition went out of print. The novel was adapted into a feature film in 1974.
