I was able at last to persuade my companion to take my advice, though I knew from his excited manner that there was not much hope of sleep for him. Indeed, his mood was infectious, for I lay tossing half the night myself, brooding over this strange problem, and inventing a hundred theories, each of which was more impossible than the last.

Why had he been so careful not to inform the people at Briarbrae that he intended to remain near them?
