“I did not sleep at all; did not get a wink of it all night long. Never mind,” he added with a good-natured laugh, “I shall sleep all the sounder to-night.”

But he did not. The next morning (Sunday) he looked grave and tired, and ate his breakfast almost in silence. When we had finished, he said he should like, with Lady Whitney’s permission, to speak to the landlady. Miss Gay came in at once: in a light fresh print gown and black silk apron.

“Ma’am,” began Featherston, politely, “something is wrong with that bedroom overhead. What is it?”

“Something wrong, sir?” repeated Miss Gay, her meek face flushing. “Wrong in what way, sir?”

“I don’t know,” answered Featherston; “I thought perhaps you could tell me: any way, it ought to be seen to. It is something that scares away sleep. I give you my word, ma’am, I never had two such restless nights in succession in all my life. Two such strange nights. It was not only that sleep would not come near me; that’s nothing uncommon you may say; but I lay in a state of uneasy, indescribable restlessness. I have examined the room again this morning, and I can see nothing to induce it, yet a cause there must undoubtedly be. The paper is not made of arsenic, I suppose?”

“The paper is pale pink, sir,” observed Miss Gay. “I fancy it is the green papers that have arsenic in them.”

“Ay; well. I think there must be poison behind the paper; in the paste, say,” went on Featherston. “Or perhaps another paper underneath has arsenic in it?”

Miss Gay shook her head, as she stood with her hand on the back of a chair. Lady Whitney had asked her to sit down, but she declined. “When I came into the house six months ago, that room was re-papered, and I saw that the walls were thoroughly scraped. If you think there’s anything—anything in the room that prevents people sleeping, and—and could point out what it is, I’m sure, sir, I should be glad to remedy it,” said Miss Gay, with uncomfortable hesitation.

But this was just what Featherston, for all he was a doctor, could not point out. That something was amiss with the room, he felt convinced, but he had not discovered what it was, or how it could be remedied.

“After lying in torment half the night, I got up and lighted my candle,” said he. “I examined the room and opened the window to let the cool breeze blow in. I could find nothing likely to keep me awake, no stuffed-up chimney, no accumulation of dust, and I shut the window and got into bed again. I was pretty cool by that time and reckoned I should sleep. Not a bit of it, ma’am. I lay more restless than ever, with the same unaccountable feeling of discomfort and depression upon me. Just as I had felt the night before.”
