In Le Crime est notre affaire the 2008 French adaptation by Pascal Thomas of 4.50 from Paddington, Raphaël Charpentier is the parallel of Harold Crackenthorpe in the original novel. He is portrayed by Alexandre Lafaurie.
Like Harold, Raphaël is a banker. He normally lives in Lyons with his wife Diane but visits "La vallée des loups" (the Rutherford Hall equivalent) for Christmas. In this case, he comes alone because Diane hates winters in France and is away in New York until near the end of the story. Raphaël's niece Alexie Charpentier describes him as "weird". He is a gambler and only interested in money and drugs.
Like Harold in the original, Raphaël is killed after taking some pills which he receives by post.
