"Would you mind looking them up? It is important for all our sakes to substantiate the truth of this lady's words. Have you any idea, Mrs. Mainwaring, about what month your husband and Mr. Leigh went to the Continent?"
"Just after their degree examination," she replied. "They took their degrees together—that would be about this time of year."
"June ten years back," commented the manager. He seemed much impressed now, and his manner showed me how greatly he was interested.
"I will go downstairs immediately and examine the books," he said.
He returned in about ten minutes with a bewildered face.
"You are right, madam," he exclaimed; "but the good Lord only knows what it all means. I hunted up the visitors' book of ten years back, and there were the two names entered in the book as plain as you please: Edward Mainwaring, Walter Leigh. Mr. Leigh occupied No. 25 and Mr. Mainwaring the room next to it, No. 26. Now, what does all this mean?"
"That Mr. Mainwaring has forgotten ten years of his life," I answered, promptly. "He must be carefully watched during the night. Can you give Mrs. Mainwaring a bedroom? I shall also sleep at the hotel."
The manager was now only too anxious to attend to our requirements. Mrs. Mainwaring was conducted to a room on the next floor and I occupied the bedroom next Mainwaring's, which happened to be empty.
Nothing occurred during the night, which was spent by me in anxious and wakeful conjecture.
At an early hour the next morning I joined Mrs. Mainwaring. One glance at her face showed me through what terrible suffering she had been passing. I told her without preamble what I considered the best and only thing to do.
