When the luxurious Blue Train arrives at Nice, a guard attempts to wake serene Ruth Kattering from her slumbers. But she will never wake again-for a heavy blow has killed her, disfiguring her features almost beyond recognition. What is more, her precious rubies are missing.

This thriller is gripping till the end, taking twists and turns making is more suspicious only and of course the plot and language of Agatha Christie is as always articulate and engrossing.
