Bond goes to San Francisco and meets with CIA agent Chuck Lee, who claims Zorin is the product of medical experimentation with steroids performed by Dr. Carl Mortner, a Nazi scientist who is now Zorin's physician. Bond then investigates a nearby oil rig owned by Zorin, and while there finds KGB agent Pola Ivanova recording conversations and her partner placing explosives on the rig. Ivanova's partner is caught and killed, but Ivanova and Bond escape. Later Ivanova takes the recording, but finds that Bond had switched tapes.
