Gertrude had slipped out during my talk with Mrs. Watson, and I dressed and went down-stairs. The billiard and card-rooms were locked until the coroner and the detectives got there, and the men from the club had gone back for more conventional clothing.

I could hear Thomas in the pantry, alternately wailing for Mr. Arnold, as he called him, and citing the tokens that had precursed the murder. The house seemed to choke me, and, slipping a shawl around me, I went out on the drive. At the corner by the east wing I met Liddy. Her skirts were draggled with dew to her knees, and her hair was still in crimps.

"Go right in and change your clothes," I said sharply. "You're a sight, and at your age!"

She had a golf-stick in her hand, and she said she had found it on the lawn. There was nothing unusual about it, but it occurred to me that a golf-stick with a metal end might have been the object that had scratched the stairs near the card-room. I took it from her, and sent her up for dry garments. Her daylight courage and self-importance, and her shuddering delight in the mystery, irritated me beyond words. After I left her I made a circuit of the building. Nothing seemed to be disturbed: the house looked as calm and peaceful in the morning sun as it had the day I had been coerced into taking it. There was nothing to show that inside had been mystery and violence and sudden death.

In one of the tulip beds back of the house an early blackbird was pecking viciously at something that glittered in the light. I picked my way gingerly over through the dew and stooped down: almost buried in the soft ground was a revolver! I sc.r.a.ped the earth off it with the tip of my shoe, and, picking it up, slipped it into my pocket. Not until I had got into my bedroom and double-locked the door did I venture to take it out and examine it. One look was all I needed. It was Halsey's revolver. I had unpacked it the day before and put it on his shaving-stand, and there could be no mistake. His name was on a small silver plate on the handle.

I seemed to see a network closing around my boy, innocent as I knew he was. The revolver-I am afraid of them, but anxiety gave me courage to look through the barrel-the revolver had still two bullets in it. I could only breathe a prayer of thankfulness that I had found the revolver before any sharp-eyed detective had come around.

I decided to keep what clues I had, the cuff-link, the golf-stick and the revolver, in a secure place until I could see some reason for displaying them. The cuff-link had been dropped into a little filigree box on my toilet table. I opened the box and felt around for it. The box was empty-the cuff-link had disappeared!

CHAPTER V

GERTRUDE'S ENGAGEMENT

At ten o'clock the Casanova hack brought up three men. They introduced themselves as the coroner of the county and two detectives from the city. The coroner led the way at once to the locked wing, and with the aid of one of the detectives examined the rooms and the body. The other detective, after a short scrutiny of the dead man, busied himself with the outside of the house. It was only after they had got a fair idea of things as they were that they sent for me.

I received them in the living-room, and I had made up my mind exactly what to tell. I had taken the house for the summer, I said, while the Armstrongs were in California. In spite of a rumor among the servants about strange noises-I cited Thomas-nothing had occurred the first two nights. On the third night I believed that some one had been in the house: I had heard a crashing sound, but being alone with one maid had not investigated. The house had been locked in the morning and apparently undisturbed.

Then, as clearly as I could, I related how, the night before, a shot had roused us; that my niece and I had investigated and found a body; that I did not know who the murdered man was until Mr. Jarvis from the club informed me, and that I knew of no reason why Mr. Arnold Armstrong should steal into his father's house at night. I should have been glad to allow him entree there at any time.

"Have you reason to believe, Miss Innes," the coroner asked, "that any member of your household, imagining Mr. Armstrong was a burglar, shot him in self-defense?"

"I have no reason for thinking so," I said quietly.

"Your theory is that Mr. Armstrong was followed here by some enemy, and shot as he entered the house?"

"I don't think I have a theory," I said. "The thing that has puzzled me is why Mr. Armstrong should enter his father's house two nights in succession, stealing in like a thief, when he needed only to ask entrance to be admitted."

The coroner was a very silent man: he took some notes after this, but he seemed anxious to make the next train back to town. He set the inquest for the following Sat.u.r.day, gave Mr. Jamieson, the younger of the two detectives, and the more intelligent looking, a few instructions, and, after gravely shaking hands with me and regretting the unfortunate affair, took his departure, accompanied by the other detective.

I was just beginning to breathe freely when Mr. Jamieson, who had been standing by the window, came over to me.

"The family consists of yourself alone, Miss Innes?"

"My niece is here," I said.

"There is no one but yourself and your niece?"

"My nephew." I had to moisten my lips.

"Oh, a nephew. I should like to see him, if he is here."

"He is not here just now," I said as quietly as I could. "I expect him-at any time."

"He was here yesterday evening, I believe?"

"No-yes."

"Didn't he have a guest with him? Another man?"

"He brought a friend with him to stay over Sunday, Mr. Bailey."

"Mr. John Bailey, the cashier of the Traders' Bank I believe." And I knew that some one at the Greenwood Club had told. "When did they leave?"

"Very early-I don't know at just what time."

Mr. Jamieson turned suddenly and looked at me.

"Please try to be more explicit," he said. "You say your nephew and Mr. Bailey were in the house last night, and yet you and your niece, with some women-servants, found the body. Where was your nephew?"

I was entirely desperate by that time.

"I do not know," I cried, "but be sure of this: Halsey knows nothing of this thing, and no amount of circ.u.mstantial evidence can make an innocent man guilty."

"Sit down," he said, pushing forward a chair. "There are some things I have to tell you, and, in return, please tell me all you know. Believe me, things always come out. In the first place, Mr. Armstrong was shot from above. The bullet was fired at close range, entered below the shoulder and came out, after pa.s.sing through the heart, well down the back. In other words, I believe the murderer stood on the stairs and fired down. In the second place, I found on the edge of the billiard-table a charred cigar which had burned itself partly out, and a cigarette which had consumed itself to the cork tip. Neither one had been more than lighted, then put down and forgotten. Have you any idea what it was that made your nephew and Mr. Bailey leave their cigars and their game, take out the automobile without calling the chauffeur, and all this at-let me see certainly before three o'clock in the morning?"

"I don't know," I said; "but depend on it, Mr. Jamieson, Halsey will be back himself to explain everything."

"I sincerely hope so," he said. "Miss Innes, has it occurred to you that Mr. Bailey might know something of this?"

Gertrude had come down-stairs and just as he spoke she came in. I saw her stop suddenly, as if she had been struck.

"He does not," she said in a tone that was not her own. "Mr. Bailey and my brother know nothing of this. The murder was committed at three. They left the house at a quarter before three."

"How do you know that?" Mr. Jamieson asked oddly. "Do you KNOW at what time they left?"

"I do," Gertrude answered firmly. "At a quarter before three my brother and Mr. Bailey left the house, by the main entrance. I-was-there."

"Gertrude," I said excitedly, "you are dreaming! Why, at a quarter to three-"

"Listen," she said. "At half-past two the downstairs telephone rang. I had not gone to sleep, and I heard it. Then I heard Halsey answer it, and in a few minutes he came up-stairs and knocked at my door. We-we talked for a minute, then I put on my dressing-gown and slippers, and went down-stairs with him. Mr. Bailey was in the billiard-room. We-we all talked together for perhaps ten minutes. Then it was decided that-that they should both go away-"

"Can't you be more explicit?" Mr. Jamieson asked. "WHY did they go away?"

"I am only telling you what happened, not why it happened," she said evenly. "Halsey went for the car, and instead of bringing it to the house and rousing people, he went by the lower road from the stable. Mr. Bailey was to meet him at the foot of the lawn. Mr. Bailey left-"

"Which way?" Mr. Jamieson asked sharply.

"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.
