Singleton walked on, halting now and then to make a careful scrutiny all round, and continuing to whistle softly to himself all the time.
Somehow his mind continually found itself reverting to Geordie’s story. It was an old wife’s tale, of course, but a queer one too. And this was the very terrace on which the old warrior used to walk, and that little turret-chamber there was his room! Ah! strange how the reflection of the moon should make it appear as if there were a light in the room! If he were not certain no light was there, he could have vowed that was one. Bah! he wished Geordie had kept his story to himself, it made him feel quite dismal.
Hark! A footstep!
He was certain he heard one, close at his side too. He stood still and listened. Everything was silent. He moved on again. There! he heard it distinctly! almost in step with his own. He looked up and down, everywhere; and then Geordie’s words rushed back on his memory, “If ever again a coward should be laird of Singleton, that old man—”
Here he stepped forward, and again suddenly halted. The footstep that time was as distinct as his own. Pooh! what if it was? He was not going to be afraid of all the ghosts in Scotland! and he laughed out loud by way of assuring himself of his nerve. But he had hardly done so, when just above him sounded another laugh, mocking his own, and as he stepped suddenly forward, the footsteps began again as clear as ever.
This was more than Singleton had bargained for; and he sat down on the end of the gun in bewilderment and alarm. Had any one been there to see his face it would have appeared a good deal paler than was its wont; and it was certainly something more than the cold that made him shiver. He sat perfectly still and listened. There was not a sound. He strained his eyes on every hand. Nothing was visible through the darkness but the silent terrace on which he watched. What could it be? As he sat and wondered, the pike which had been resting carelessly across his knee slipped and fell on to the stone pavement with a sudden clank, which was instantly repeated overhead, just as the laugh and the footsteps had been.
Of course it flashed upon Singleton then—an echo! nothing but a simple echo among the nooks and crannies of the castle; and at a simple echo his cheek had turned pale and his heart had stood still, and his hands had actually trembled! He scorned himself bitterly for his cowardice; and once more, relieved in mind and humbled in spirit, set out on his night watch, determined this time that nothing, not even a score of ghosts, should terrify him.
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.
