"Just give me my glasses for a moment, Williams," I said, and in a trice he had handed me the pair I had brought down for the inspection next day. Seating myself in the window, I brought them to bear upon the spot where the birds had flown out. For a moment I could see nothing. Then I thought I could detect what looked like a grey trouser-leg, peeping out beneath the branches of a fir. I called Williams to my side and handed him the glasses, directing him where to look. "What do you make of it?" I asked. "It looks as if there's somebody hiding there, sir," he answered. "Yes, sir, I'm sure of it," he added a few moments later. "If you will look now, you will be able to see him creeping away." I took the glasses again and once more turned them upon the spot. What he had said was quite correct; the figure of a man dressed in a grey suit could just be distinguished disappearing into the deeper part of the wood. It immediately occurred to me that the man I had seen that afternoon, when we were on our way to the Park, had also been dressed in grey. Could this be the individual who had watched us then? And if so, what were his reasons for behaving in this mysterious fashion? I did not like the idea of it, remembering as I did the dangerous condition of the times, and the manner in which so many of my friends had been attacked. "Keep what you have seen to yourself, Williams," I said; "I will speak to Lord Beckingdale myself about it when I go downstairs. If the man is a poacher, or has any dishonest reason for being there, he will know what to do in the matter." Williams promised to obey my instructions, and when I had dressed, I made my way downstairs to find our host and the Commander-in-Chief standing before the fire-place, in which a cheerful fire was burning. "By the way, Beckingdale," I said, when I had answered the remark one of them made to me as I descended the stairs, "who is the man in your plantation with the grey suit and field-glasses." "Man with grey suit and field-glasses?" he repeated, with a look of surprise on his face. "I have many friends who are the happy possessors of both articles. But what makes you ask me such a question at the present moment?" "For a good and sufficient reason," I replied, and went on to tell him of the two occasions that afternoon upon which I had seen the person in question. "What a singular thing!" he said, when I had finished. "I wonder who the fellow is, and what his idea can be in watching the house? As you are aware, the place is being patrolled by police to-night, and I think I had better inform them of the circumstance. After the terrible events of the last few weeks it does not do to run any risks. Can you describe the man?"
