16.50 ab Paddington.

Agatha Christie’s audacious mystery thriller, reissued with a striking new cover designed to appeal to the latest generation of Agatha Christie fans and book lovers. For an instant the two trains ran together, side by side. In that frozen moment, Elspeth witnessed a murder. Helplessly, she stared out of her carriage window as a man remorselessly tightened his grip around a woman’s throat. The body crumpled. Then the other train drew away. But who, apart from Miss Marple, would take her story seriously? After all, there were no suspects, no other witnesses… and no corpse.
