The 'Heart of Fire' is one of the world's legendary jewels which once adorned the crown of the Tsars.

But legend proclaims the stunning ruby brings death in its wake. So the American millionaire Rufus Van Aldin may live to regret his purchase...

As the glamorous Blue Train carries the rich and the famous to their beloved Riviera - the future looks far from bright for one passenger...

It's another case for Agatha Christie's Belgian sleuth, Hercule Poirot.
