Both say right away, this novel has nothing to do with the camera inside the Orient Express by Agatha imagined Christie.Une young woman is murdered in a train from Marseille to capitale.Dans day following his unfortunate companions are eliminated implacablement.L'enquête is conducted by a group of inspectors from the dock goldsmiths ... A little detective that does not break three legs to a duck but is rather well built and whose end is rather surprising, though I am to the insight that Michel Drucker is the impertinence (some may have guessed from the eighth page) .Amateurs of detective novels, there is a pleasant enough moment.Pour there are other better anyway.
