One of the very best Christie mysteries read by Hercule Poirot himself, David Suchet.

Just after midnight, a snowdrift stopped the Orient Express in its tracks. The luxurious train was surprisingly full for the time of the year. But by the morning there was one passenger fewer. An American lay dead in his compartment, stabbed a dozen times, his door locked from the inside.

With tension mounting, detective Hercule Poirot comes up with not one, but two solutions to the crime.
