The man who called himself Harry Brogan had had many names in his time. Like a chameleon he changed his appearance, too, according to circumstances and the task he had been given. In the world of espionage it was the only way he could hope to survive.

Soon Brogan is embroiled in a gigantic conspiracy -- an attempt to destroy our civilization.
