"No," said the cab driver, shaking his head, "it was the top floor, and thankful I was there wasn't any more of 'em." "Did you see any one else in the apartment?" asked Peter, carefully restraining his impatience. "Not a soul," answered the man, "and I don't think there was anybody else there. It was awful quiet. I didn't see anybody and I didn't hear anybody moving around." "Did you notice anything unusual about the apartment?" asked Peter. "Was it--what you'd call--tidy--when you were there?" "I don't know," said Bill, scratching his head. "I ain't much of a hand at noticing things, I'm afraid. Places is apt to be a bit upset when people are going away. I didn't think anything about that. I only just went into the back room to get the trunk--and----" A sudden thought seemed to strike him--"now I come to think of it, I did get just a little peek at the lady's face as I was coming along the hall with the trunk on me back. She'd watched me strap it up, and then she went ahead of me into a room off the hall, toward the front. When I come along, she was standing over by the window, and there was a looking glass on the wall right in front of her. She'd just held up her veil to look for something on the little table there was there, and I saw her in the glass, just for a second, before she pulled the veil down again." He paused, and added, doubtfully, "Did the lady you was lookin' for have a kind of a scar or something on her face, on--let's see--on this side?" He touched his right cheek. Morris suppressed an exclamation, and Peter leaned still farther forward. "What kind of a scar, Bill?" he asked, quietly. "I don't know, exactly," answered the driver, hesitatingly. "The window was on the other side and I couldn't see so very plain, but it seemed to me there was some kind of a dark red mark on her cheek and down on her neck. I can't be sure, but I thought there was. I only saw it for a second. Does that help you any?" "H'm'm----" said Peter. "Maybe. Maybe it will, Bill.... And you're pretty sure there wasn't any one else in the apartment?" "Well," said Bill, "I'll leave it to you. I didn't see nobody and I didn't hear nobody, and when I took the trunk out, she was out on the stairs already, and she asked me to make sure the door was locked. And why would she be nervous about that, I asks you, if there was someone inside?" "Doesn't seem reasonable, does it?" said Peter, thoughtfully. "But I don't quite see----You say the lady was in the bedroom when you passed the door, but she was outside, on the stairs, when you took the trunk out. How was that?"
