"In that case," rejoined Sir Patrick, "I had better go on at once with the matter in hand--leaving you to see for yourself the connection between what I am about to say, and the question that I have just put. When I have done, you shall then reply to me or not, exactly as you think right. My dear boy, the subject on which I want to speak to you is--Miss Silvester."
Arnold started. Sir Patrick looked at him with a moment's attention, and went on:
"My niece has her faults of temper and her failings of judgment," he said. "But she has one atoning quality (among many others) which ought to make--and which I believe will make--the happiness of your married life. In the popular phrase, Blanche is as true as steel. Once her friend, always her friend. Do you see what I am coming to? She has said nothing about it, Arnold; but she has not yielded one inch in her resolution to reunite herself to Miss Silvester. One of the first questions you will have to determine, after to-morrow, will be the question of whether you do, or not, sanction your wife in attempting to communicate with her lost friend."
Arnold answered without the slightest reserve "I am heartily sorry for Blanche's lost friend, Sir Patrick. My wife will have my full approval if she tries to bring Miss Silvester back--and my best help too, if I can give it."
Those words were earnestly spoken. It was plain that they came from his heart.
"I think you are wrong," said Sir Patrick. "I, too, am sorry for Miss Silvester. But I am convinced that she has not left Blanche without a serious reason for it. And I believe you will be encouraging your wife in a hopeless effort, if you encourage her to persist in the search for her lost friend. However, it is your affair, and not mine. Do you wish me to offer you any facilities for tracing Miss Silvester which I may happen to possess?"
"If you _can_ help us over any obstacles at starting, Sir Patrick, it will be a kindness to Blanche, and a kindness to me."
"Very good. I suppose you remember what I said to you, one morning, when we were talking of Miss Silvester at Windygates?"
"You said you had determined to let her go her own way."
"Quite right! On the evening of the day when I said that I received information that Miss Silvester had been traced to Glasgow. You won't require me to explain why I never mentioned this to you or to Blanche. In mentioning it now, I communicate to you the only positive information, on the subject of the missing woman, which I possess. There are two other chances of finding her (of a more speculative kind) which can only be tested by inducing two men (both equally difficult to deal with) to confess what they know. One of those two men is--a person named Bishopriggs, formerly waiter at the Craig Fernie inn."
Arnold started, and changed color. Sir Patrick (silently noticing him) stated the circumstances relating to Anne's lost letter, and to the conclusion in his own mind which pointed to Bishopriggs as the person in possession of it.
"I have to add," he proceeded, "that Blanche, unfortunately, found an opportunity of speaking to Bishopriggs at Swanhaven.
When she and Lady Lundie joined us at Edinburgh she showed me privately a card which had been given to her by Bishopriggs. He had described it as the address at which he might be heard of--and Blanche entreated me, before we started for London, to put the reference to the test. I told her that she had committed a serious mistake in attempting to deal with Bishopriggs on her own responsibility; and I warned her of the result in which I was firmly persuaded the inquiry would end. She declined to believe that Bishopriggs had deceived her. I saw that she would take the matter into her own hands again unless I interfered; and I went to the place. Exactly as I had anticipated, the person to whom the card referred me had not heard of Bishopriggs for years, and knew nothing whatever about his present movements. Blanche had simply put him on his guard, and shown him the propriety of keeping out of the way. If you should ever meet with him in the future--say nothing to your wife, and communicate with me. I decline to assist you in searching for Miss Silvester; but I have no objection to assist in recovering a stolen letter from a thief. So much for Bishopriggs.--Now as to the other man."
"Who is he?"
"Your friend, Mr. Geoffrey Delamayn."
Arnold sprang to his feet in ungovernable surprise.
"I appear to astonish you," remarked Sir Patrick.
