Bruno Wildermann of the Wrinfield Circus is the world's greatest trapeze artist, a clairvoyant with near-supernatural powers and an implacable enemy of the East German regime that arrested his family and murdered his wife. The CIA needs such a man for an impossible raid on the impregnable Lubylan Fortress where his family is held, to remove a dangerous weapons formula from a heavily guarded laboratory under cover of a traveling circus tour, Bruno prepares to return to his homeland. But before the journey even begins a murderer strikes twice. Somewhere in the circus there is a communist agent with orders to stop Bruno at any cost. [editor summary]
