176 pp. A challenging assignment from TEEN takes Chris Cool to London on a dual mission: to search for information about his father who is being held prisoner behind the Iron Curtain, and to intercept a formula devised by an Oriental scientist which threatens the world with a monstrous plague. Clues involving giant insects lead Chris and his Indian partner, Geronimo Johnson, to a London suburb where their enemies spring a macabre trap for the kill. By playing the dangerous game of double agent, Chris masterfully pits the TOAD spy organization against the wily Dracov combine. When these forces of evil collide, the fireworks light up the most diabolical plot ever to menace Great Britain.
