Spying Blind (1968)

THE PLOTTERS: a megalomanic millionaire, a double-dealing con man, and a beautiful hophead. THE PLACE: a floating pleasure palace on the Mediterranean with a hold as big as the Ritz. THE PLAN: to intercept a Russin moon-shot just as it returns to earth. THE PRIZE: a payload that could ransom the world. It was fantastic, bizarre, incredible, and Intertrust Agent Mark Hood didn't believe it. Not until he saw the conspirators were dead serious, and that he had to be serious to - or dead.

Mark Hood gets a fantastic proposition. Help a lovely junkie hijack a Russian moon-shot. All she has to offer is love -- or death.
