There is a straight and quiet path behind Kensington Palace which the lovers and nursery-maids of Kensington Gardens frequent but little. A line of low-growing knotted trees separates it from the Broad Walk at a little distance. A hedge and fence on the other side divides the Gardens from a strip of meadow not yet covered by buildings. The public esteem this particular walk but lightly. Invalids in bath-chairs toil down it sometimes; nurses with grown-up children, who are children still, go there occasionally, where the uncouth gambols and vacant bearded laugh of forty-five will not attract attention. But as a rule it is deserted. Colonel Tempest had it almost to himself for the first ten minutes, except for a covey of little boys who fought and clambered and jumped on some stacked timber at one end. He had not chosen the place without forethought. It would be presumed that he would have a large sum of money with him, and he had taken care on each occasion to select a rendezvous where foul play would not be possible. He was within reach of numbers of persons merely by raising his voice. An old man on the arm of a young one passed him slowly, absorbed in earnest conversation. A girl in mourning sat down on one of the benches. There was privacy enough for business, and not too much for safety. Colonel Tempest paced up and down, giving each face that passed a furtive glance. He did not know what to expect. The three quarters struck. The girl got up and turned away. A stout, shabby-looking man, whose approach Colonel Tempest had not noticed, was sitting on one of the benches under a gnarled yew, staring vacantly in front of him. The old man and the young one were coming down the walk again. A check suit with six depressed, amber-eyed dachshunds in a leash passed among the trees. A few more turns. The clock began to strike six. Colonel Tempest's pulse quickened. As he turned once more at the end of the walk, he could see that the hunched-up figure, with the hat over the eyes, was still sitting under the yew at the further end. He walked slowly towards it. How should they recognize each other? Who would speak first? A quietly-dressed man, walking rapidly in the opposite direction, touched his hat respectfully as he passed him. Colonel Tempest recognized John's valet, and slackened his pace, for he was approaching the bench under the yew tree, and he did not care to be addressed while any one was within earshot. He was opposite it now, and he looked hard at the occupant. The latter stared vacantly, if not sleepily, back at him, and made no sign. "He is shamming," said Colonel Tempest to himself. "Or else he is not sure of me." And he took yet another turn.
