"By the main entrance.
He left—it was a quarter to three.
I know exactly."
"The clock in the hall is stopped, Miss Innes," said Jamieson.
Nothing seemed to escape him.
"He looked at his watch," she replied, and I could see Mr. Jamieson's snap, as if he had made a discovery.
As for myself, during the whole recital I had been plunged into the deepest amazement.
"Will you pardon me for a personal question?"
The detective was a youngish man, and I thought he was somewhat embarrassed.
"What are your—your relations with Mr. Bailey?"
Gertrude hesitated.
Then she came over and put her hand lovingly in mine.
"I am engaged to marry him," she said simply.
I had grown so accustomed to surprises that I could only gasp again, and as for Gertrude, the hand that lay in mine was burning with fever.
"And—after that," Mr. Jamieson went on, "you went directly to bed?"
Gertrude hesitated.
"No," she said finally.
"I—I am not nervous, and after I had extinguished the light, I remembered something I had left in the billiard-room, and I felt my way back there through the darkness."
"Will you tell me what it was you had forgotten?"
"I can not tell you," she said slowly.
"I—I did not leave the billiard-room at once—"
"Why?" The detective's tone was imperative.
"This is very important, Miss Innes."
"I was crying," Gertrude said in a low tone.
"When the French clock in the drawing-room struck three, I got up, and then—I heard a step on the east porch, just outside the card-room.
Some one with a key was working with the latch, and I thought, of course, of Halsey.
When we took the house he called that his entrance, and he had carried a key for it ever since.
The door opened and I was about to ask what he had forgotten, when there was a flash and a report.
Some heavy body dropped, and, half crazed with terror and shock, I ran through the drawing-room and got up-stairs—I scarcely remember how."
She dropped into a chair, and I thought Mr. Jamieson must have finished.
But he was not through.
"You certainly clear your brother and Mr. Bailey admirably," he said.
"The testimony is invaluable, especially in view of the fact that your brother and Mr. Armstrong had, I believe, quarreled rather seriously some time ago."
"Nonsense," I broke in.
"Things are bad enough, Mr. Jamieson, without inventing bad feeling where it doesn't exist.
Gertrude, I don't think Halsey knew the—the murdered man, did he?"
But Mr. Jamieson was sure of his ground.
"The quarrel, I believe," he persisted, "was about Mr. Armstrong's conduct to you, Miss Gertrude.
He had been paying you unwelcome attentions."
And I had never seen the man!
When she nodded a "yes" I saw the tremendous possibilities involved.
If this detective could prove that Gertrude feared and disliked the murdered man, and that Mr. Armstrong had been annoying and possibly pursuing her with hateful attentions, all that, added to Gertrude's confession of her presence in the billiard-room at the time of the crime, looked strange, to say the least.
The prominence of the family assured a strenuous effort to find the murderer, and if we had nothing worse to look forward to, we were sure of a distasteful publicity.
Mr. Jamieson shut his note-book with a snap, and thanked us.
"I have an idea," he said, apropos of nothing at all, "that at any rate the ghost is laid here.
Whatever the rappings have been—and the colored man says they began when the family went west three months ago—they are likely to stop now."
Which shows how much he knew about it.
The ghost was not laid: with the murder of Arnold Armstrong he, or it, only seemed to take on fresh vigor.
Mr. Jamieson left then, and when Gertrude had gone up-stairs, as she did at once, I sat and thought over what I had just heard.
Her engagement, once so engrossing a matter, paled now beside the significance of her story.
