Bruce (Galloping) Foxley is the name of a preparatory school boy who once made life hell for William Perkins, who now commutes on the same train every day to his job in London. Perkins notices another passenger who he is convinced must be Foxley, the bane of his youth. In his mind, Perkins relives the torture and abuse of his school days at the hands of the sadistic bully Foxley. Perkins determines to introduce himself, which he does. The other man does likewise, but he is not Foxley.
