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.
