A hilarious and whip-smart crime novel by the multimillion-copy bestselling author of the Horrible Histories. The perfect mystery for fans of Anthony Horowitz, Richard Osman and Janice Hallett.

Four strangers on a train. An unlikely introduction:

'Actually, I'm a murderer.'

It is 1973 and the lives of four people are thrown into turmoil when sharing a carriage with an unremarkable little man with glasses, on the night train back to Newcastle.

By the end of the following day, one of them will be dead, one will turn blackmailer and another forced to commit a crime. And all of them will be under the astute observation of Aline, the local police officer with her own agenda to fulfil.

When the body count begins to rise, the question is: just how many murderers are out there... and who will be the next victim?
