And now the night began to wear on. By this time the men must be very near their rendezvous, for it was an hour past midnight, and the moon was getting down towards the west. He wondered what other clans would muster round the royal standard, and how soon the king's forces would be likely to meet the enemy. This time to-morrow he would be with his men; that is, provided the general permitted ten of them to return and relieve guard here. Supposing no one came! At that moment Jupiter gave a very low growl, which made his master stop short in his march and listen with all his ears. For a long time not a sound was audible, and then he fancied he could just detect the tramp of a horse or horses in the far far distance. But that seemed to die away, and again all was utterly silent. But once more, just as he was starting again on his walk, Jupiter growled, and this time rose to his feet and came to his master's side. Yes, it was the sound of horses somewhere; more than one, too. With straining ears and beating heart, the youth leant on his pike, and listened. The sound grew more and more distinct, and presently he could tell that, whoever they were, they were galloping. He ordered Jupiter to lie down and be silent. They were in the wood, somewhere. Were they bound for Singleton? Presently he was able to distinguish voices, and a minute afterwards it seemed as if every sound had ceased. He stepped quietly, followed by Jupiter, from the east terrace to the rampart over the great gate, where he was able to command as full a view as the uncertain light would allow of the glade through the frees which led to the castle. But nothing could be seen. As he watched, the sounds commenced again, and this time he fancied he could detect a rumbling noise as of a cart accompanying the horsemen. It was now easy to tell the meaning of all these sounds. A troop of horsemen--he could not yet guess how many--were approaching Singleton Towers; and bringing with them a gun! The young laird's heart beat now in right earnest, but not with fear. That had been left behind with the ghosts. He forgot everything but the defence of his castle and the glory of his clan; and waited eagerly for the time of action. The cavalcade made a halt about halfway through the wood, and in the still night air, with the light breeze carrying it, Singleton could hear the sound of voices as in hurried consultation. Then a single horseman approached; and before many minutes he could just discern in the dim moonlight a form emerging from the wood and stealthily approaching the castle. "Let him come and spy," said Singleton, to himself. "He will see the lights, and perhaps a few spear-heads on the walls--and he'll report as much to his chief. Ah!"
