“Don’t be silly,” she interrupted. “I’m not a fool, and please don’t mistake me for one. After I went to the cabin and heard the five short blasts of the whistle, I knew someone had gone overboard. Naturally, I guessed who that someone must have been. There I was, standing with my wet clothes on the floor and my husband’s money belt in my hand. I knew what it was going to look like as well as you did. So I decided to change my clothes and hide the money belt.”

“Where was your husband when you left him?”

“On the boat deck.”

“You know where the hospital is up there?”

“There’s the little cluster of rooms in a cabin off by itself, with...?”

“That’s the place,” Mason said.

“Yes, I know where it is.”

“Was there a light in the hospital?”

“No,” she said, “I don’t think so. It was dark up there.”

“Did you see anyone else on the boat deck?”
