He offered no further information. For a long while Arthur was puzzled by the movements that followed this last remark. Apparently the Clockwork man desired to change his tactics; he did not wish to prolong the conversation. But, in his effort to move away, he was obviously hampered by the fact that his hand still rested upon Arthur's shoulder. He did not seem to be able to bend his arm in a natural fashion. Instead, he kept on making a half-right movement of his body, with the result that every time he so moved he was stopped by the impingement of his hand against Arthur's neck. At last he solved the problem. He took a quick step backwards, nearly losing his balance in the process, and cleared his arm, which he then lowered in the usual fashion. Then he turned sharply to the left, considered for a moment, and waddled away. There was no other term, in Arthur's estimation, to describe his peculiar gait. He took no stride; he simply lifted one foot up and then the other, and then placed them down again slightly ahead of their former positions. His body swayed from side to side in tune with his strange walk. After he had progressed a few yards he turned to the right, with a smart movement, and looked approximately in Arthur's direction. His mouth opened and shut very rapidly, and there floated across the intervening space some vague and very unsatisfactory human noise, obviously intended as an expression of leave-taking. Then he turned to the left again, with the same drill-like action, and waddled along. IV Arthur watched him, feeling diffident, half inclined to follow him in case he fell over. For there was not much stability about the Clockwork man. It was clear that the slightest obstacle would have precipitated him upon his nose. He kept his head erect, and looked neither downwards or to right and left. He seemed wholly absorbed in his eccentric mode of locomotion, as though he found it interesting just to be moving along. Arthur kept his eyes glued upon that stiff, upright back, surmounted by the wig and hat, and he wondered what would happen when the Clockwork man reached to the end of the line of hurdles, where another barrier started at right angles across the end of the cricket ground. It was a sight to attract attention, but fortunately, as Arthur thought, everybody seemed too absorbed in the game to notice what was happening. The dawning of humour saved him from some uncomfortable misgivings. There was something uncanny about the experience. Somehow, it didn't seem natural, but it was certainly funny. It was grotesque. You had to laugh at that odd-looking figure, or else feel cold all over with another kind of sensation. Of course, the man was mad. He was, in spite of his denial, an escaped lunatic. But the noise? That was certainly difficult to explain. Perhaps he had some kind of infernal machine hidden in his pocket, in which case he would be a dangerous kind of lunatic.
