(1967)
In Europe with a U.S. team, skydiver Fathom Harvill is approached by a Scottish colonel working for a top-secret Western agency. He's after a vital lost atomic device, and wants her to parachute into a house occupied by some Red Chinese to help get the thing back. Apart from all this there is a predatory continental doctor on his yacht to take account of. Fathom soon realises none of this is as it seems, but can she fathom the truth out? 55 Written by Jeremy Perkins
