I told all I knew--how Parks had announced a man's arrival, how Vantine and I had come downstairs together, how Vantine had called me, and finally how Parks had identified the body as that of the strange caller. "Have you any theory about it?" Goldberger asked. "Only that the call was merely a pretext--that what the man was really looking for was a place where he could kill himself unobserved." "How long a time elapsed after Parks announced the man before you and Mr. Vantine came downstairs?" "Half an hour, perhaps." Goldberger nodded. "Let's have Parks in," he said. I opened the door and called to Parks, who was sitting on the bottom step of the stair. Goldberger looked him over carefully as he stepped into the room; but there could be no two opinions about Parks. He had been with Vantine for eight or ten years, and the earmarks of the competent and faithful servant were apparent all over him. "Do you know this man?" Goldberger asked, with a gesture toward the body. "No, sir," said Parks. "I never saw him till about an hour ago, when Rogers called me downstairs and said there was a man to see Mr. Vantine." "Who is Rogers?" "He's the footman, sir. He answered the door when the man rang." "Well, and then what happened?" "I took his card up to Mr. Vantine, sir." "Did Mr. Vantine know him?" "No, sir; he wanted to know what he wanted." "What _did_ he want?" "I don't know, sir; he couldn't speak English hardly at all--he was French, I think." Goldberger looked down at the body again and nodded. "Go ahead," he said. "And he was so excited," Parks added, "that he couldn't remember what little English he did know." "What made you think he was excited?" "The way he stuttered, and the way his eyes glinted. That's what makes me think he just come in here to kill hisself quiet like--I shouldn't be surprised if you found that he'd escaped from somewhere. I had a notion to put him out without bothering Mr. Vantine--I wish now I had--but I took his card up, and Mr. Vantine said for him to wait; so I come downstairs again, and showed the man in here, and said Mr. Vantine would see him presently, and then Rogers and me went back to our lunch and we sat there eating till the bell rang, and I came in and found Mr. Vantine here." "Do you mean to say that you and Rogers went away and left this stranger here by himself?" "The servants' dining-room is right at the end of the hall, sir. We left the door open so that we could see right along the hall, clear to the front door. If he'd come out into the hall, we'd have seen him." "And he didn't come out into the hall while you were there?" "No, sir." "Did anybody come in?" "Oh, no, sir; the front door has a snap-lock. It can't be opened from the outside without a key." "So you are perfectly sure that no one either entered or left the house by the front door while you and Rogers were sitting there?"
