One woman. A sealed train. Twenty suspects. One killer. A woman is found dead among the mail sacks in the guard van of a night express. Not her compartment. Not her name on the ticket. Inspector Mercer has the doors held at Bruges. Nobody boards. Nobody steps down. Whoever did this is still aboard, eating the same bad soup. He has no warrant card. What he has is a register of twenty-five thousand names and a note from the dead woman's glove, written in marks nobody can read. One truth at every stop. By the last station, twenty people are left, and you sit down with all of them. This is an elimination puzzle book. Cross names off the manifest, clue by clue, until one is left. No prior knowledge needed. Just bring a pencil. What's inside: A sealed train 21 clues 20 interrogations 1 cipher to crack 1 killer to unmask Can you name the killer before the last station?
