"I think even Goldenburg was taken aback, for the revelation that I was playing double came as a shock to him. He laughed at me at first, but I could see that he had lost his temper. Then he swore at me for a Jezebel, and half rose as though he would strike me. But I was first. There was a dagger on the mantelpiece. For a moment I saw red. When I was again capable of thought I saw Goldenburg lying on the couch, motionless, and I knew what I had done. "I struggled to get a grip on myself. At any moment Grell might return. I could not be sure of what he might do, and my whole idea was to save myself at any cost. Goldenburg had fallen back on the couch. I had taken two steps to the door when there was a sound outside. I drew back behind a curtain, expecting Grell. Instead of that a woman came in. She was heavily veiled, and though I did not know her then I was positive it was Lady Eileen Meredith, for Goldenburg had hinted at some such dramatic surprise if Grell did not come to terms. I saw her stoop over the murdered man, and then Grell opened the door. He stared for a second, and then closed the door again just as Lady Eileen looked up. "To him it must have appeared that she had killed the man. I expected her to scream, but she did nothing of the sort. She went out, closing the door softly. I followed her within a minute or so, for I began to have an idea how things might be turned to my advantage. I went straight back to my hotel, and made arrangements to secure a sort of alibi. But I wanted to know how things were going. I had told Grell that if it became necessary to write me under cover, he might do so at the _poste restante_, Folkestone. There it was I heard before I returned to London. He declared that he had killed Goldenburg, a statement I had the best of reasons for knowing was false. But it left me with an easier mind. I had no wish that he should be questioned by the police, for that might have given rise to questions as to why I was at the house, and how I left. "That was why I helped him by every means in my power. I think now it would have been perfectly easy for me to have disappeared without raising more than a fleeting suspicion in any one's mind. But we cannot foresee everything. And I believed that my safety lay in keeping Grell at liberty. What he thought of my motives for helping him, I do not know--he may have believed them to be gratitude, or something else. Anyway, he trusted me, and to make sure, I more than once hinted that I had an idea that Lady Eileen Meredith was the guilty person.
