"Yes, there was no doubting that. Shocked, surprised, terrified, and something more. It is that something more which has proved my perplexity. I cannot make it out, not even in thinking it over. Was it the fascination which all horrible sights exert on the morbid, or was it a sudden realization of some danger he had escaped, or of some difficulty yet awaiting him? Hard to say, Mr. Gryce, hard to say; but you may take my word for it that there was more to him in this meeting than an unexpected stumbling upon a dead man where he expected to find a live one. Yet he made no sound after that first cry, and hardly any movement. He just stared at the figure on the floor; then at his face, which he seemed to devour, at first with curiosity, then with hate, then with terror, and lastly--how can I express myself?--with a sort of hellish humor that in another moment might have broken into something like a laugh, if the bird, which I had failed to observe up to this moment, had not waked in its high cage, and, thrusting its beak between the bars, shrilled out in the most alarming of tones: 'Remember Evelyn!' That startled the old man even more than the sight on the floor had done. He turned round, and I saw his fist rise as if against some menacing intruder, but it quickly fell again as his eyes encountered the picture which hung before him, and with a cringe painful to see in one of his years, he sidled back till he reached the doorway. Here he paused a minute to give another look at the man outstretched at his feet, and I heard him say: "'It is Amos's son, not Amos! Is it fatality, or did he plan this meeting, thinking----' "But here he caught sight of my figure in the antechamber beyond, and resuming in an instant his former debonair manner, he bowed very low and opened his lips as if about to ask a question. But he evidently thought better of it, for he strode by me and made his way to the front door without a word. Being an intruder myself, I did not like to stop him. But I am sorry now for the consideration I showed him; for just before he stepped out, his emotion--the special character of which, I own to you, I find impossible to understand--culminated in a burst of raucous laughter which added the final horror to this amazing adventure. Then he went out, and in the last glimpse I had of him before the door shut he wore the same look of easy self-satisfaction with which he had entered this place of death some fifteen minutes before." "Remarkable! Some secret history there! That man must be found. He can throw light upon Mr. Adams's past. 'Amos's son,' he called him? Who is Amos? Mr. Adams's name was Felix. Felix, the son of Amos. Perhaps this connection of names may lead to something. It is not a common one, and if given to the papers, may result in our receiving a clew to a mystery which seems impenetrable. Your stay in Mr. Adams's house was quite productive, ma'am. Did you prolong it after the departure of this old man?"
