In this official authorized edition featuring exclusive content from the Queen of Mystery, robbery and brutal murder aboard a luxury transport ensnares the ever-attentive Hercule Poirot.

When the luxurious Blue Train arrives at Nice, a guard attempts to wake serene Ruth Kettering 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.

The prime suspect is Ruth’s estranged husband, Derek. Yet Hercule Poirot is not convinced, so he stages an eerie reenactment of the journey, complete with the murderer on board...

隨著柯特林的情婦、受害者的父親及名珠寶商的相繼出現，案情愈呈複雜,是情殺？仇殺？財殺？還是自古以來引發無數殺戮的「火心寶石」再度索命？
