On a London train, Quiller spots an enemy agent that killed a friend of his. Taking matters into his own hands, Q executes the enemy spy, but not as discretely as his booses would have liked and Quiller is now being sought by the police. As punishment for his sins, Quiller is sent on a suicide mission to steal a Russian warplane. As always with the Bureau, the mission is not quite what it seems.
Not Hall's best, but even fair Quiller is better than 95% of the action/espionage genre. ( )
