At dinner Mr. Jamieson suggested sending a man out in his place for a couple of days, but Halsey was certain there would be nothing more, and felt that he and Alex could manage the situation. The detective went back to town early in the evening, and by nine o'clock Halsey, who had been playing golf--as a man does anything to take his mind away from trouble--was sleeping soundly on the big leather davenport in the living-room.
I sat and knitted, pretending not to notice when Gertrude got up and wandered out into the starlight. As soon as I was satisfied that she had gone, however, I went out cautiously. I had no intention of eavesdropping, but I wanted to be certain that it was Jack Bailey she was meeting. Too many things had occurred in which Gertrude was, or appeared to be, involved, to allow anything to be left in question.
I went slowly across the lawn, skirted the hedge to a break not far from the lodge, and found myself on the open road. Perhaps a hundred feet to the left the path led across the valley to the Country Club, and only a little way off was the foot-bridge over Casanova Creek. But just as I was about to turn down the path I heard steps coming toward me, and I shrank into the bushes. It was Gertrude, going back quickly toward the house.
I was surprised. I waited until she had had time to get almost to the house before I started. And then I stepped back again into the shadows. The reason why Gertrude had not kept her tryst was evident. Leaning on the parapet of the bridge in the moonlight, and smoking a pipe, was Alex, the gardener. I could have throttled Liddy for her carelessness in reading the torn note where he could hear. And I could cheerfully have choked Alex to death for his audacity.
But there was no help for it: I turned and followed Gertrude slowly back to the house.
The frequent invasions of the house had effectually prevented any relaxation after dusk. We had redoubled our vigilance as to bolts and window-locks but, as Mr. Jamieson had suggested, we allowed the door at the east entry to remain as before, locked by the Yale lock only. To provide only one possible entrance for the invader, and to keep a constant guard in the dark at the foot of the circular staircase, seemed to be the only method.
In the absence of the detective, Alex and Halsey arranged to change off, Halsey to be on duty from ten to two, and Alex from two until six. Each man was armed, and, as an additional precaution, the one off duty slept in a room near the head of the circular staircase and kept his door open, to be ready for emergency.
These arrangements were carefully kept from the servants, who were only commencing to sleep at night, and who retired, one and all, with barred doors and lamps that burned full until morning.
The house was quiet again Wednesday night. It was almost a week since Louise had encountered some one on the stairs, and it was four days since the discovery of the hole in the trunk-room wall.
Arnold Armstrong and his father rested side by side in the Casanova churchyard, and at the Zion African Church, on the hill, a new mound marked the last resting-place of poor Thomas.
Louise was with her mother in town, and, beyond a polite note of thanks to me, we had heard nothing from her. Doctor Walker had taken up his practice again, and we saw him now and then flying past along the road, always at top speed. The murder of Arnold Armstrong was still unavenged, and I remained firm in the position I had taken--to stay at Sunnyside until the thing was at least partly cleared.
And yet, for all its quiet, it was on Wednesday night that perhaps the boldest attempt was made to enter the house. On Thursday afternoon the laundress sent word she would like to speak to me, and I saw her in my private sitting-room, a small room beyond the dressing-room.
Mary Anne was embarrassed. She had rolled down her sleeves and tied a white apron around her waist, and she stood making folds in it with fingers that were red and shiny from her soap-suds.
"Well, Mary," I said encouragingly, "what's the matter? Don't dare to tell me the soap is out."
"No, ma'm, Miss Innes." She had a nervous habit of looking first at my one eye and then at the other, her own optics shifting ceaselessly, right eye, left eye, right eye, until I found myself doing the same thing. "No, ma'm. I was askin' did you want the ladder left up the clothes chute?"
"The what?" I screeched, and was sorry the next minute. Seeing her suspicions were verified, Mary Anne had gone white, and stood with her eyes shifting more wildly than ever.
"There's a ladder up the clothes chute, Miss Innes," she said. "It's up that tight I can't move it, and I didn't like to ask for help until I spoke to you."
It was useless to dissemble; Mary Anne knew now as well as I did that the ladder had no business to be there. I did the best I could, however. I put her on the defensive at once.
"Then you didn't lock the laundry last night?"
"I locked it tight, and put the key in the kitchen on its nail."
"Very well, then you forgot a window."
Mary Anne hesitated.
"Yes'm," she said at last. "I thought I locked them all, but there was one open this morning."
I went out of the room and down the hall, followed by Mary Anne. The door into the clothes chute was securely bolted, and when I opened it I saw the evidence of the woman's story. A pruning- ladder had been brought from where it had lain against the stable and now stood upright in the clothes shaft, its end resting against the wall between the first and second floors.
I turned to Mary.
"This is due to your carelessness," I said. "If we had all been murdered in our beds it would have been your fault." She shivered. "Now, not a word of this through the house, and send Alex to me."
The effect on Alex was to make him apoplectic with rage, and with it all I fancied there was an element of satisfaction. As I look back, so many things are plain to me that I wonder I could not see at the time. It is all known now, and yet the whole thing was so remarkable that perhaps my stupidity was excusable.
Alex leaned down the chute and examined the ladder carefully.
"It is caught," he said with a grim smile. "The fools, to have left a warning like that! The only trouble is, Miss Innes, they won't be apt to come back for a while."
"I shouldn't regard that in the light of a calamity," I replied.
Until late that evening Halsey and Alex worked at the chute. They forced down the ladder at last, and put a new bolt on the door. As for myself, I sat and wondered if I had a deadly enemy, intent on my destruction.
I was growing more and more nervous. Liddy had given up all pretense at bravery, and slept regularly in my dressing-room on the couch, with a prayer-book and a game knife from the kitchen under her pillow, thus preparing for both the natural and the supernatural. That was the way things stood that Thursday night, when I myself took a hand in the struggle.
