McGill's friend, a Russian defector, has absconded with a million dollars and hidden the safety-deposit box key. Some people will kill to get it, and when one of them succeeds, McGill finds himself caught in the middle.

Mac sees a chance to clear his name when the daughter of Harry Thyssen, the man who ordered him to let LeFabre defect, reports that her father is back from the dead. She soon drops the claim but Mac figures that he's onto something, even though his former superiors warn him off the case.
