Again, as in the room downstairs, there flashed through my mind the suspicion that I had got into a place where people took drugs or drink—or were all out of their minds. I had heard of such houses.

"How can I help her? She won't confide in me, and even if she did, what could I do for her?"

"You can stand by and watch. You can come between her and harm—if you see it." She had risen from the floor and stood wiping her reddened eyes on the napkin. "I don't know what it is, but I know it is there. I feel it even when I can't see it."

Yes, they were all out of their minds; there couldn't be any other explanation. The whole episode was incredible. It was the kind of thing, I kept telling myself, that did not happen. Even in a book nobody could believe it.

"But her husband? He is the one who must protect her."

She gave me a blighting look. "He would if he could. He isn't to blame—you mustn't think that. He is one of the best men in the world, but he can't help her. He can't help her because he doesn't know. He doesn't see it."

A bell rang somewhere, and catching up the tea-tray, she paused just long enough to throw me a pleading word, "Stand between her and harm, if you see it."

When she had gone I locked the door after her, and turned on all the lights in the room. Was there really a tragic mystery in the house, or were they all mad, as I had first imagined? The feeling of apprehension, of vague uneasiness, which had come to me when I entered the iron doors, swept over me in a wave while I sat there in the soft glow of the shaded electric light. Something was wrong. Somebody was making that lovely woman unhappy, and who, in the name of reason, could this somebody be except her husband? Yet the maid had spoken of him as "one of the best men in the world," and it was impossible to doubt the tearful sincerity of her voice. Well, the riddle was too much for me. I gave it up at last with a sigh—dreading the hour that would call the downstairs to meet Mr. Vanderbridge. I felt in every nerve and fibre of my body that I should hate him the moment I looked at him.

But at eight o'clock, when I went reluctantly downstairs, I had a surprise. Nothing could have been kinder than the way Mr. Vanderbridge greeted me, and I could tell as soon as I met his eyes that there wasn't anything vicious or violent in his nature. He reminded me more than ever of the portrait in the loan collection, and though he was so much older than the Florentine nobleman, he had the same thoughtful look. Of course I am not an artist, but I have always tried, in my way, to be a reader of personality; and it didn't take a particularly keen observer to discern the character and intellect in Mr. Vanderbridge's face. Even now I remember it as the noblest face I have ever seen; and unless I had possessed at least a shade of penetration, I doubt if I should have detected the melancholy. For it was only when he was thinking deeply that this sadness seemed to spread like a veil over his features. At other times he was cheerful and even gay in his manner; and his rich dark eyes would light up now and then with irrepressible humour. From the way he looked at his wife I could tell that there was no lack of love or tenderness on his side any more than there was on hers. It was obvious that he was still as much in love with her as he had been before his marriage, and my immediate perception of this only deepened the mystery that enveloped them. If the fault wasn't his and wasn't hers, then who was responsible for the shadow that hung over the house?

For the shadow was there. I could feel it, vague and dark, while we talked about the war and the remote possibilities of peace in the spring. Mrs. Vanderbridge looked young and lovely in her gown of white satin with pearls on her bosom, but her violet eyes were almost black in the candlelight, and I had a curious feeling that this blackness was the colour of thought. Something troubled her to despair, yet I was as positive as I could be of anything I had ever been told that she had breathed no word of this anxiety or distress to her husband. Devoted as they were, a nameless dread, fear, or apprehension divided them. It was the thing I had felt from the moment I entered the house; the thing I had heard in the tearful voice of the maid. One could scarcely call it horror, because it was too vague, too impalpable, for so vivid a name; yet, after all these quiet months, horror is the only word I can think of that in any way expresses the emotion which pervaded the house.
