"That gentleman across the road, the one with his back to us, is keeping your house under surveillance," I said to Bryce. "I suppose he's afraid the place'll run away."
"Afraid I'll run away, more likely," Bryce answered. "Evidently he doesn't want to be identified next time we meet. But he needn't worry over that; I wouldn't know him from a bar of soap. We'll leave him alone for the time being, Carstairs, and get this machine in. I don't see any reason why we should let this gentleman delay our dinner."
"No more do I. Let her out."
I stood on the step of the car until it had passed the entrance in safety, then I went back and made the gate fast. But before doing so I just couldn't resist taking a peep at the Roman sentry figure of a man opposite. He was staring straight at the gate—as if that was going to help him in any way—but he was pretty alert. The moment he sighted me he wheeled about and walked off in another direction. But, quick and all as he was, I caught a passing glimpse of him. He had on a blue serge suit, a rather cheap affair as well as I could judge at that distance, and a black felt hat. Somehow I got the impression, though I was too far away to say anything with certainty, that he was not so much sallow as sunburnt. It was more than likely that he had not got a good look at me—in that case he would not know me again, as I flattered myself that there was nothing very distinctive about me. Still, as that marksman behind the rocks must have been taking stock of me for some considerable while, I realised that no definite advantage would accrue from the fact that one of the gang might not be able to identify me. I had no means of ascertaining how many there were in the organisation, and something warned me not to display too much interest in Bryce's presence. When I walked down the path and discovered him backing the car into his garage I made no comment on the situation beyond telling him that the spy had gone temporarily out of business and was at present taking a constitutional down the street.
"All we can do then," Bryce said, "is to let him depart in peace and trust that nothing happens. I wouldn't like any of that bunch to be cut off in the midst of their sins. I've got another end mapped out for them."
"If you figure me in on that, you're mighty mistaken," I said to myself. "I'm the first line of defence, but I'll be hanged if I'm going to carry the war into the enemy's country."
I needn't have been so cocksure about it, for as will shortly be related that was just exactly what I did do.
