In the pitch darkness of the London Blackout, assassins' bullets struck home with deadly accuracy, for somehow, incredibly - the killers had the power to see in the dark. Gordon Craigie, head of Britain's top security Department Z, faced the gravest challenge of his career - for if that power fell into enemy hands, all Europe would be imperiled.
