"'Nothing of the island of Madeira.'
"He turned his head away, and began talking to himself.
"'Strange!' he said. 'As certainly as I was in the Shadow's place at the window, she was in the Shadow's place at the pool!'
"Under other circumstances, his extraordinary behavior might have alarmed me. But after his question about Madeira, there was some greater fear in me which kept all common alarm at a distance. I don't think I ever determined on anything in my life as I determined on finding out how he had got his information, and who he really was. It was quite plain to me that I had roused some hidden feeling in him by my question about Armadale, which was as strong in its way as his feeling for me. What had become of my influence over him?
"I couldn't imagine what had become of it; but I could and did set to work to make him feel it again.
"'Don't treat me cruelly,' I said; 'I didn't treat you cruelly just now. Oh, Mr. Midwinter, it's so lonely, it's so dark--don't frighten me!'
"'Frighten you!' He was close to me again in a moment. 'Frighten you!' He repeated the word with as much astonishment as if I had woke him from a dream, and charged him with something that he had said in his sleep.
"It was on the tip of my tongue, finding how I had surprised him, to take him while he was off his guard, and to ask why my question about Armadale had produced such a change in his behavior to me. But after what had happened already, I was afraid to risk returning to the subject too soon. Something or other--what they call an instinct, I dare say--warned me to let Armadale alone for the present, and to talk to him first about himself. As I told you in one of my early letters, I had noticed signs and tokens in his manner and appearance which convinced me, young as he was, that he had done something or suffered something out of the common in his past life. I had asked myself more and more suspiciously every time I saw him whether he was what he appeared to be; and first and foremost among my other doubts was a doubt whether he was passing among us by his real name. Having secrets to keep about my own past life, and having gone myself in other days by more than one assumed name, I suppose I am all the readier to suspect other people when I find something mysterious about them. Any way, having the suspicion in my mind, I determined to startle him, as he had startled me, by an unexpected question on my side--a question about his name.
