Mason nodded, lit a cigarette and said, “How do you suppose Rosalind’s going to feel when she learns that Driscoll tried to divert suspicion from himself by involving Rita Swaine?”

“You surely don’t think he did that?” Cuff asked.

“Yes, he did exactly that.”

Cuff thought for a moment, then said, “One thing you may be overlooking, Mr. Mason: Before this inquest started, the district attorney was preparing extradition proceedings against both Rita Swaine and Rosalind Prescott. As matters now stand, he will proceed to extradite Rita Swaine. He can’t extradite Rosalind Prescott — not in the face of this evidence.”

“And you think that’s a good thing?” Mason asked.

“I think so, yes.”

“For whom?”

“For Rosalind Prescott, primarily.”

“How about Miss Swaine?” Mason inquired.

“Miss Swaine,” Cuff told him, “will have to take care of herself — with your very able assistance.”
