An MI5 agent is unsure whom he can trust when a ghost from his past returns in this Cold War thriller by the author of Red Corona

March 1966. The Cold War is in full effect. Paranoia and conspiracies are running rampant in London. Agents on both sides of the Iron Curtain are chasing shadows, and MI5 agent Richard Knox has had enough of it.

Meanwhile, his friend, CIA agent Abey Bennett is left feeling disillusioned about her career after a mishap in the Caribbean. Then a stranger stops her in the street. He claims to be the Soviet super-agent, "the Wolf," and he knows an awful lot about Bennett. He also needs her help . . .

Bennett's arrival in London with the Wolf at her side sends a jolt through Knox. He knows the man from his past. What's even more troubling is the information the stranger shares with him.

Now Knox is faced with a terrible choice of whom to believe--and whom to betray . . .
