"How would he know it?" I demanded, incredulously.
"If he is keeping an eye on this window, as he naturally would do, he has seen my light. Perhaps he is watching us now."
I glanced at the dark square of the window with a little shiver. This business was getting on my nerves again. But Godfrey turned away with a shrug of the shoulders.
"Now for the cabinet," he said, and led the way back upstairs.
Rogers was still sitting dejectedly on the cot, and, looking at him more closely, I could see that he was white and shaken. His trouble, whatever its nature, plainly lay heavy on his mind.
"Have you anything to tell us, this evening, Rogers?" I asked, kindly, but he only shook his head.
"I've told you everything I know, sir," he answered, in a low voice.
"I'm not going to worry you, Rogers," I went on, "but I want you to think it over. You can rely upon me to help you, if I can."
He looked up quickly, but caught himself, and turned his eyes away.
"Thank you, sir," was all he said.
