"All the time that she was telling me this story she never once looked in my direction, and her voice was quite unlike her usual tones. It was evident to me that she was saying what was false. I said nothing in reply, but turned my face to the wall, sick at heart, with my mind filled with a thousand venomous doubts and suspicions. What was it that my wife was concealing from me? Where had she been during that strange expedition? I felt that I should have no peace until I knew, and yet I shrank from asking her again after once she had told me what was false. All the rest of the night I tossed and tumbled, framing theory after theory, each more unlikely than the last.
"I should have gone to the City that day, but I was too disturbed in my mind to be able to pay attention to business matters. My wife seemed to be as upset as myself, and I could see from the little questioning glances which she kept shooting at me that she understood that I disbelieved her statement, and that she was at her wits' end what to do. We hardly exchanged a word during breakfast, and immediately afterwards I went out for a walk, that I might think the matter out in the fresh morning air.
"I went as far as the Crystal Palace, spent an hour in the grounds, and was back in Norbury by one o'clock. It happened that my way took me past the cottage, and I stopped for an instant to look at the windows, and to see if I could catch a glimpse of the strange face which had looked out at me on the day before. As I stood there, imagine my surprise, Mr. Holmes, when the door suddenly opened and my wife walked out.
"I was struck dumb with astonishment at the sight of her; but my emotions were nothing to those which showed themselves upon her face when our eyes met. She seemed for an instant to wish to shrink back inside the house again; and then, seeing how useless all concealment must be, she came forward, with a very white face and frightened eyes which belied the smile upon her lips.
"'Ah, Jack,' she said, 'I have just been in to see if I can be of any assistance to our new neighbors. Why do you look at me like that, Jack? You are not angry with me?'
"'So,' said I, 'this is where you went during the night.'
"'What do you mean?" she cried.
"'You came here. I am sure of it. Who are these people, that you should visit them at such an hour?'
"'I have not been here before.'
"'How can you tell me what you know is false?' I cried. 'Your very voice changes as you speak. When have I ever had a secret from you? I shall enter that cottage, and I shall probe the matter to the bottom.' "'No, no, Jack, for God's sake!' she gasped, in uncontrollable emotion. Then, as I approached the door, she seized my sleeve and pulled me back with convulsive strength.
"'I implore you not to do this, Jack,' she cried. 'I swear that I will tell you everything some day, but nothing but misery can come of it if you enter that cottage.' Then, as I tried to shake her off, she clung to me in a frenzy of entreaty.
"'Trust me, Jack!' she cried. 'Trust me only this once. You will never have cause to regret it. You know that I would not have a secret from you if it were not for your own sake. Our whole lives are at stake in this. If you come home with me, all will be well. If you force your way into that cottage, all is over between us.'
"There was such earnestness, such despair, in her manner that her words arrested me, and I stood irresolute before the door.
"'I will trust you on one condition, and on one condition only,' said I at last. 'It is that this mystery comes to an end from now. You are at liberty to preserve your secret, but you must promise me that there shall be no more nightly visits, no more doings which are kept from my knowledge. I am willing to forget those which are passed if you will promise that there shall be no more in the future.'
"'I was sure that you would trust me,' she cried, with a great sigh of relief. 'It shall be just as you wish. Come awayoh, come away up to the house.'
"Still pulling at my sleeve, she led me away from the cottage. As we went I glanced back, and there was that yellow livid face watching us out of the upper window. What link could there be between that creature and my wife? Or how could the coarse, rough woman whom I had seen the day before be connected with her? It was a strange puzzle, and yet I knew that my mind could never know ease again until I had solved it.
"For two days after this I stayed at home, and my wife appeared to abide loyally by our engagement, for, as far as I know, she never stirred out of the house. On the third day, however, I had ample evidence that her solemn promise was not enough to hold her back from this secret influence which drew her away from her husband and her duty.
"I had gone into town on that day, but I returned by the 2.40 instead of the 3.36, which is my usual train. As I entered the house the maid ran into the hall with a startled face. "'Where is your mistress?' I asked. "'I think that she has gone out for a walk,' she answered.
"My mind was instantly filled with suspicion. I rushed upstairs to make sure that she was not in the house. As I did so I happened to glance out of one of the upper windows, and saw the maid with whom I had just been speaking running across the field in the direction of the cottage. Then of course I saw exactly what it all meant. My wife had gone over there, and had asked the servant to call her if I should return. Tingling with anger, I rushed down and hurried across, determined to end the matter once and forever. I saw my wife and the maid hurrying back along the lane, but I did not stop to speak with them. In the cottage lay the secret which was casting a shadow over my life. I vowed that, come what might, it should be a secret no longer. I did not even knock when I reached it, but turned the handle and rushed into the passage.
"It was all still and quiet upon the ground floor. In the kitchen a kettle was singing on the fire, and a large black cat lay coiled up in the basket; but there was no sign of the woman whom I had seen before. I ran into the other room, but it was equally deserted. Then I rushed up the stairs, only to find two other rooms empty and deserted at the top. There was no one at all in the whole house. The furniture and pictures were of the most common and vulgar description, save in the one chamber at the window of which I had seen the strange face. That was comfortable and elegant, and all my suspicions rose into a fierce bitter flame when I saw that on the mantelpiece stood a copy of a fell-length photograph of my wife, which had been taken at my request only three months ago.
"I stayed long enough to make certain that the house was absolutely empty. Then I left it, feeling a weight at my heart such as I had never had before. My wife came out into the hall as I entered my house; but I was too hurt and angry to speak with her, and pushing past her, I made my way into my study. She followed me, however, before I could close the door.
"'I am sorry that I broke my promise, Jack,' said she; 'but if you knew all the circumstances I am sure that you would forgive me.'
"'Tell me everything, then,' said I.
"'I cannot, Jack, I cannot,' she cried.
"'Until you tell me who it is that has been living in that cottage, and who it is to whom you have given that photograph, there can never be any confidence between us,' said I, and breaking away from her, I left the house. That was yesterday, Mr. Holmes, and I have not seen her since, nor do I know anything more about this strange business. It is the first shadow that has come between us, and it has so shaken me that I do not know what I should do for the best. Suddenly this morning it occurred to me that you were the man to advise me, so I have hurried to you now, and I place myself unreservedly in your hands. If there is any point which I have not made clear, pray question me about it. But, above all, tell me quickly what I am to do, for this misery is more than I can bear."
