“She has a son by a former marriage, Steven Watkins,” Sabin went on. “I have sometimes referred to him as his mother’s stool pigeon. He has developed conscious affability as an asset. He has the technique of a politician, the character of a rattlesnake. He has been East for some time, and took the plane from New York to connect with the plane that will pick up his mother in Central America. They will arrive together.”
