Spoiler:

When the night train pulled into Paris, she was dead. And the riddle began...

A beautiful young woman lies sprawled on her berth in the sleeping car of the night train from Marseille to Paris. She is not in the embrace of sleep, or even in the arms of one of her many lovers. She is dead. And the unpleasant task of finding her killer is handed to overworked, crime-weary police detective Pierre ‘Grazzi’ Grazziano, who would rather play hide-and-seek with his little son than cat and mouse with a diabolically cunning, savage murderer.

With corpses turning up everywhere, the question becomes not only who is the killer, but who will be the next victim . . .

I had an ARC of this a while back and really liked it, especially right at the beginning, where the train worker who will find the body is busy musing about an upcoming strike - what could be more French? If you want to read my full review, it's on my blog...
