Who wrote "Murder on the Orient Express"?

I once collected the entire series of Hercule Poirot Murder mysteries. It was a collection that, if all the books were arranged in chronological order, the spines formed a complete picture of the man himself, with a train (The Orient Express) in the background, from the first to the last book. I moved abroad and gave the entire collection to my local library. The lady librarian thought she had died and gone to Heaven!

onkardil, which one, the modern one or the one with Albert Finney... cos I don't think the modern one was as good as the original, ok
