Résumé: When Cain's former employers turn on him, it's "Once Upon A Time in the West" country as a team of heavies is despatched by train to Devon to shut him up. As his allies evaporate one by one, Cain is increasingly beset by questions about just whose side his mentor was on. Back in a London brought to a halt by the oil crisis, the only person who can answer those questions is being held hostage by terrorists. And as the government sees its plans unravelling, it calls in a little American help to remove the thorn in its side: No-Face, the deadly Yankee dandy.
