"You knew nothing of what had occurred at the house until the gardener told you in the morning?"

"N--yes--no, sir," Brown stammered, with another glance towards Mrs. LaGrange, who was watching him closely.

"What did you say?" demanded the coroner.

"I said I didn't know what had happened till Uncle Mose told me,"

Brown answered, doggedly.

"That will do," said the coroner, watching the witness narrowly as he resumed his place among the servants.

During the latter part of Brown's testimony, quick, telegraphic glances had been exchanged between Scott and Mr. Sutherland, and one or two slips of paper, un.o.bserved by any one but Merrick, had pa.s.sed from one to the other.

Scott was well aware that the statements made by the coachman had deepened suspicion against himself. He paid little attention to the crowd, however, but noted particularly the faces of the guests at Fair Oaks. Ralph Mainwaring's, dark with anger; that of the genial Mr. Thornton coldly averted; young Mainwaring's supercilious stare, and his sister's expression of contemptuous disdain; and as he studied their features his own grew immobile as marble. Suddenly his glance encountered Miss Carleton's face and was held for a moment as though under a spell. There was no weak sentimentality there, no pity or sympathy,--he would have scorned either,--but the perfect confidence shining in her eyes called forth a quick response from his own, though not a muscle stirred about the sternly-set mouth. She saw and understood, and, as her eyes fell, a smile, inexplicable and mysterious, flashed for an instant across her face and was gone.

"John Wilson," announced the coroner, after a slight pause.

A middle-aged man, rather dull in appearance, except for a pair of keenly observant eyes, stepped forward with slow precision.

"You are Mr. Ralph Mainwaring's valet, I believe?" said the coroner.

"That I am, sir," was the reply.

"Have you been for some time in his employ?"

The man peered sharply at Dr. Westlake from under his heavy brows, and replied, with great deliberation, "Nigh onto thirty years, sir."

Then, noting the surprise in his interlocutor's face, he added, with dignity, "The Wilsons, sir, have served the Mainwarings for three generations. My father, sir, was valet to the father of the dead Hugh Mainwaring, the Honorable Ralph Maxwell Mainwaring, sir."

A smile played over the features of young Mainwaring at these words, but Scott started involuntarily, and, after studying Wilson's face intently for a moment, hastily pencilled a few words on a slip of paper which he handed to Mr. Sutherland, and both watched the witness with special interest.

His testimony differed little from that given by Hardy and by the butler. He stated, however, that, after accompanying Mr. Ralph Mainwaring to the scene of the murder, the latter sent him to summon Mr. Scott; but on his way to the young gentleman's room he saw Mr.

Whitney in advance of him, who called the secretary and immediately returned with him to the library.

"Was Mr. Scott already up when Mr. Whitney called him?" the coroner inquired, quickly.

"He was up and dressed, sir," was the reply.

Wilson also corroborated the butler's statement that Walter LaGrange was not seen about the premises until luncheon, and stated, in addition, that the horse belonging to young LaGrange was missing from the stables until nearly noon. Having mingled very little with the servants at Fair Oaks, he had but slight knowledge concerning the occurrences of the day preceding the murder. His testimony was therefore very brief.

"Katie O'Brien, chambermaid," was next called; and in response a young Irish woman quietly took her place before the coroner. She answered the questions addressed her as briefly as possible, but with deliberation, as though each word had been carefully weighed.

"Did you have charge of the private rooms of Mr. Mainwaring?"

"Yes, sir."

"You took care of his rooms as usual Wednesday?"

"Yes, sir."

"Did you see Mr. Mainwaring during the day or evening?"

"I met him once or twice in the halls."

"When did you last see him?"

"About two o'clock Wednesday afternoon."

"State how you first heard of his death."

"I was working in the halls up-stairs about seven that morning and heard running back and forth, as if there was trouble. I went out into the front hall and met the butler, and he told me Mr. Mainwaring had been murdered."

"Did you go in to see him at that time?"

"Yes, sir, for a moment."

"Did you notice anything unusual in his rooms?"

"I didn't notice anything unusual in Mr. Mainwaring's rooms."

"Did you in any room?"

"Yes, sir."

"In what one?"

"In Mr. Scott's room, a little later."

"State what you observed."

"A few minutes after I left the library I saw Mr. Scott come out of his room and go away with Mr. Whitney, and I thought I would go in and do up the room. So I went in, but the bed was just as I had made it up the day before. It hadn't been slept in nor touched.

Then things was strewn around considerable, and the top drawer of his dressing-case was kept locked all the forenoon until he went to the city."

"When did he go to the city?"

"About noon."

"Did you see Mr. Scott the day or evening preceding Mr. Mainwaring's death?"

"No, sir; but I know he was locked in Mr. Mainwaring's library all the afternoon, after the folks had gone out driving."

"How do you know the library was locked?"

"I was sweeping in the corridor, and I heard him unlock the door when the butler came up with some gentleman's card."

"Did you see the gentleman who came up-stairs later?"

"No, sir."

"Did you see Walter LaGrange at any time during yesterday forenoon?"
