By this time they were galloping along the road.

"We must time our pace well by theirs." They were going at a sharp trot. "Whatever we do, we must not show on the road behind them. You had better drop back and ride a good quarter of a mile behind me. If they see one solitary horseman far in the rear they would not think much of it, but if they saw two of us they might possibly suppose that we were following them. I must get a sight of them occasionally, no matter how far off, so as to be sure that they have not turned off from the main road."

Roper reined in his horse, and Arthur rode forward until he came to the crest of a slight brow, and as his head rose above this he could make out the horsemen a mile and a half in advance. The instant he did so he checked his horse and dismounted for a few minutes. When he went forward he saw that the group of horsemen were a mere black mass on the road. Feeling certain that a single figure could not be made out at that distance, he rode on at a gallop. Now and then he caught sight of them, but when he did so he always checked his horse for a time. At last, on reaching the crest of a hill he stopped suddenly and dismounted, for he saw a group gathered in front of a wayside inn not more than half a mile away. He left his horse behind him, and stood against a wall so that his figure should not be seen against the sky-line.

As he looked he saw the party start again, so, waiting until they were well away, he followed. Five miles farther, when at some distance from a small town, he observed that they turned off, and had no doubt that they intended to make a circuit, so as to pass round it unobserved. He waited until Roper came up. "They have turned off here," he said. "I shall ride straight through the town, and post myself near the next road that comes in on this side. You follow them and watch the road closely. You can't help seeing the tracks of so large a party. Ride pretty fast till you sight them. If, as I expect, they take a turn again and come down upon the main road, you will know that I have followed them. If they turn off in any other direction you must trace them to their halting-place, and then ride to the junction of the two roads where I shall be waiting you. I shall remain there until you come, however long that may be, unless I follow them along the main road."

"I understand, sir. It is a comfort to know that as long as it is daylight we cannot miss them. It is when it gets dark that we shall have a difficulty."

"When it does get dark, Roper, we must muffle the feet of our horses and then close up till we can hear them; in that way we shall keep them in touch."

Arthur rode quietly through the town and halted a mile beyond it, where a road came in on the side on which he had seen the carriage turn off. He placed his horse behind a wall a few yards from the junction, and himself went forward until, stooping down behind some bushes, he could obtain sight of them as they passed. Ten minutes later he heard the clatter of horses. The advance-guard passed, and then he heard the wheels of the carriage. As it came along he could see that the blinds were still down. As he had expected, the horses had been changed. Five minutes after the last party of horsemen had passed, Roper came up.

"Stop there, Roper," Arthur said, standing up; "we must wait till they have gone a bit farther before we go out into the road. Well, I am more than ever convinced that there is someone of the very greatest importance in that carriage. The mere fact that they have taken the trouble to make this detour is sufficient in itself to show that I am afraid we are in for a long ride."

"It can't be helped, sir; it is a real bit of excitement, though not quite so exciting as it was when you carried me on your back."

"No; but the excitement will come when we have to undertake the job of finding out for certain who it is they have carried off. The fact, though, that five or six at any rate of the riders are men of importance in itself points most strongly to the idea that they have carried off the queens. I have no doubt many of them have changed horses. If it is intended to take them a long distance they will all have sent off a relay of horses, probably placed in twos and threes, to small roadside inns. We shall have to change horses too somewhere. Our animals have both had easy times, and can be reckoned upon for fifty miles; but as we have no time to give them a rest, we cannot ride them farther than that. We have gone a good twenty-five miles already. At the next wayside inn we come to we will halt for five minutes, take the bits out of their mouths, and give them some bread dipped in wine, and do the same at the end of another ten miles.
