“Do you suppose she came to the house in her boat?”

“She must have done so, she always comes that way. But she could not have gone in by the window.”

“No. How did she get in, then?”

“By the door, I suppose. Miss Remsen had a key.”

“Then, why did she leave by the window?”

“That’s what I don’t know,” the gray eyes clouded. “That’s what I can’t make out.”

“It is a hard problem. What time was it when you saw her go away?”

“I’ve no idea. We all go to bed at ten, if it isn’t our night out. So I went to my room about ten, but I couldn’t sleep.”

“Hadn’t you been asleep at all, when you saw the girl and the boat?”

“Yes, I think so. I’m quite sure I had. But my watch wasn’t going, and so I don’t know what time it was.”
