“Well, what was the idea?” Mason asked.

“Don’t you see,” Drake said, “it was some sort of a bunco game. Put one of those harnesses around a man’s head, put on a large pair of smoked goggles, and it’s just about the same as a mask. Cartman has money. He can’t move around, and he doesn’t care about publicity, so he’s been careful to keep his whereabouts from becoming generally known. His friends, however, his bankers and associates, knew all about his accident and knew he had to wear his head in a brace.

“Eves wasn’t going to the Islands on his honeymoon. He sent Evelyn Whiting over there to pick up this ringer. She was to build up his identity on the ship, and also her identity as his nurse. Then, after they’d arrived on the Mainland, she and Eves were going to put through some major swindle. But the murder on the ship attracted too much attention, and they had decided to lie low until it blew over. Then, as an unfortunate coincidence, it happened that she knew Carl Moar, and he ran into her on deck and told her his troubles. Nothing could have upset her more. It was exactly what she didn’t want. Then when you discovered that she was a witness, traced her to that place of concealment and served that subpoena on her, she knew the jig was up.”

“Then why didn’t she obey the subpoena and be in court this morning?” Mason asked. “she can be fined for contempt of court—”

“Because the swindle has gone so far they didn’t dare show up. Eves may have intended to let her testify in your behalf when he had talked with you yesterday. But after he studied the situation a bit, he realized how suicidal that would be, because it would be brought out in the trial that Evelyn Whiting had been escorting Roger P. Cartman; that Cartman had had his neck broken over on the Islands. The newspapers would mention it. Someone would see it who knew Roger P. Cartman was in a private sanitarium near Glendale. Then the fat would be in the fire. The police would investigate and quietly move in.”

Mason narrowed his eyes, bringing into view a network of fine wrinkles at the corners, as he stared into space. “Yes,” he said slowly, “I see the sketch now. But I want Evelyn Whiting’s testimony. It’s the one thing I need to bust this case wide open.”

“Well,” Drake said, “those are the facts. You can make a showing to the Court if you want to.”

“I’d a lot rather locate Evelyn Whiting and force her to testify, ” Mason said.

“How did you know that the Fell woman would blow up?”

“I’d noticed her in the dining room,” Mason said. “Whenever she wore an evening dress she left off her glasses. I’d noticed her rather particularly, because it seemed to me such an absurd gesture for a woman who had that wall of reserve thrown up around her, and who seemed to be so completely immune to emotion to sacrifice the comfort of her vision to make herself more attractive. I noticed from the way she walked that she seemed rather careful of putting her feet down, and had an idea she depended pretty strongly on her glasses. But she’s one of those opinionated persons who will cheerfully commit perjury rather than admit they’re wrong. And I knew that unless I had a photograph to show her and could definitely prove her custom of not wearing glasses with a dinner gown, she’d swear she had her glasses on that night.”
