A whimsical idea flashed into his head. They would not expect to see him; he felt sportive, the boyish instinct for fun asserting itself. What if he could surprise the two—dart out on them unawares and make them jump? The tree opposite overhung the road for several yards, its foliage was still fairly thick, for the season had been mild; the autumn frosts and gales had not yet begun; and it would provide ample shelter. He sprang off the gate, ran across the road, leapt the ditch at the side, scaled the trunk with an agility bred of long practice in Wiltshire, and was soon hidden among the leaves, some fourteen feet above the road. He filled his pocket with burrs he found still clinging to the branches, laughing inwardly as he pictured Fanshawe’s consternation when he should receive one of those prickly missiles on his head. Soon he heard the measured beat of the approaching horses. Peering between the leaves, he was disappointed to notice that the riders were not Fanshawe and Sherebiah after all. One of them, a bulky man, had a familiar appearance, the other was masked; but in the first Harry recognized Captain Aglionby, and the second in figure and bearing unmistakably recalled Monsieur de Polignac. Harry wondered what was the meaning of the mask; knowing his men, he had little doubt that some villainy was afoot. His wonder gave way to uneasiness when he found that, instead of passing the tree, they dismounted and stood exactly beneath him. They opened the gate on which he had been seated a few minutes before, and led their horses through into the field, along the stone dike at the edge, and at some distance from the gate, as Harry could just see in the gathering darkness, secured them to the wall, after some difficulty in finding anything to hitch them to. Then they returned to the road, talking in low tones, and looking expectantly up and down. "’Sdeath!" muttered Aglionby, "what has become of them?" "Raté encore une fois?" sneered Polignac, inferring the other’s meaning from his tone. "Parbleu!" growled Aglionby, adding in French: "They ought to have been here a quarter of an hour ago. They cannot be long now." Harry’s curiosity was growing. The two men were clearly expecting somebody; for a moment he wondered whether Aglionby was meditating another attempt on Sherebiah, but it could hardly be that, for the captain had looked towards Breda as he spoke, not in the other direction. He listened with all his ears. "They may as well stay away altogether if the others are here before them. We are only ten minutes ahead." "Nearer twenty, if you believe me. They were riding slowly when we saw them—a mile behind; and we saved several minutes by the short cut through the wood. There is time yet."
