Miss Langdale answered quickly, "Nothing."
"Doctor Aitken has never expressed any suspicion?" pursued Leslie.
"Oh no," she returned. "I think I would have known it if he had any. No, I've never heard him even hint at anything." It was evident that she wished us to know that she was in the confidence of the doctor.
"I think we'd better be going," interrupted Kennedy, hastily, not apparently pleased to have Leslie break in in the investigation just at present.
Miss Langdale accompanied us to the door, but before we reached it it was opened from the outside by a man who had once been and yet was handsome, although one could see that he had a certain appearance of having neglected himself.
Leslie nodded and introduced us. It was Doctor Wardlaw.
As I studied his face I could see that, as Leslie had already told us, it plainly bore the stigma of nervousness.
"Has Doctor Aitken been here?" he inquired, quickly, of the nurse.
Then, scarcely waiting for her even to nod, he added: "What did he say?
Is Mrs. Wardlaw any better?"
Miss Langdale seemed to be endeavoring to make as optimistic a report as the truth permitted, but I fancied Wardlaw read between the lines. As they talked it was evident that there was a sort of restraint between them. I wondered whether Wardlaw might not have some lurking suspicion against Aitken, or some one else. If he had, even in his nervousness he did not betray it.
"I can't tell you how worried I am," he murmured, almost to himself.
"What can this thing be?"
