"Then if he knows of our appointment he will certainly follow me!" I said, in utter amazement. "Most certainly he will. You recognise the grave peril of the situation?" "I do," I said, for I saw that Sybil must at once be seriously compromised. "But who could have known our secret? Who was the woman?" "I've never seen her before. She's an entire stranger. But that she is aware of Tibbie's movements is beyond doubt. You were evidently seen together when you met last night--or how would he know that she slept at Harker's Hotel?" I was silent. I saw the very serious danger that now lay before us. Yet why was this man in search of Tibbie? He had proposed to her, she had said, and had been refused. I recalled to my companion the fact of the photograph of the dead man being found in his bag. "Yes," Eric said. "He has recognised the victim but has some secret motive in remaining silent. Is it, I wonder, a motive of revenge?" "Against whom?" For a few moments he did not speak. Then he answered-- "Against Tibbie." I pursed my lips, for I discerned his meaning. Was it possible that Ellice Winsloe knew the truth? "Therefore, what are we to do? What do you suggest?" I asked. "You must not risk going to see Sybil to-morrow. Where is she?" I briefly explained all that we had done that day, and how and where she had gone into hiding. "Then you must send her an express letter in the morning. We must not go to see her. You are certainly watched." "But think of her," I said. "I am posing as her husband, and she will require my presence there to-morrow in order to complete the fiction." "It's too risky--far too risky," Eric declared, shaking his head dubiously. "The only way is for you to keep watch upon Winsloe," I suggested, "and warn me of his movements." "But the woman--the woman who met him by appointment in the park? She may be in his employ as spy." "Did Mason overhear anything that night when Sybil came to my room, I wonder," I said. "Never mind how they got to know," he exclaimed. "I tell you that you mustn't go near Tibbie. It's far too dangerous at this moment." His words caused me considerable apprehension. How could I leave Sybil there alone? Would not Mrs Williams and her husband think it very strange? No. She had craved my assistance, and I had promised it. Therefore, at all risks I intended to fulfil my promise. To allay Eric's fears, however, I pretended to agree with him, and made him promise to still keep watch upon Winsloe. Eric was my guest whenever in London; therefore I ordered Budd to prepare his room, and after a snack over at the club we sat smoking and talking until far into the night.
