novel, (c)1961, originally published as by Ian Stuart
This twisty tale involves one of MacLean's favorite character types, the tough, ruthless secret agent. He is sent to an island posing as a rocket scientist, on the trail of eight missing scientists. Once on the island he finds a conspiracy to blackmail the world using an experimental long-range missile.
In a beautiful MacLean twist, the agent's boss is the actual man behind the conspiracy. He sends the agent into the situation as a patsy, not realizing that the agent would be able to not only survive and escape, but would put it all together and kill him.
