"Not I," replied young Singleton, gaily. "Forward, Tam, and to-morrow, if you return, you shall hear how I fared." Tam said nothing, but setting spurs to his horse, bounded across the drawbridge and rejoined his comrades. Singleton, having watched the troop as they slowly wended their way among the trees of the wood till they were lost to sight, drew up the bridge and closed and barred the great gate. Then, with a stout though anxious heart, he turned and addressed himself to his solitary and hazardous undertaking. Sub-Chapter II. THE NIGHT WATCH. The young laird of Singleton turned slowly from the courtyard out of which his men had just ridden, back into the castle. Young as he was, and inexperienced, he knew enough of the state of his country to feel that the task which he had imposed upon himself was one of the greatest peril, not only to his own life, but to the ancestral castle of his clan, for the country swarmed with freebooters and hostile clans, on the look-out for any chance of plunder; and they, if only they got wind of the unprotected state of Singleton Towers, would lose no time, he knew, in striking a blow during the absence of the clan, which might end in the loss of the old fortress for ever. Still, what else could he have done? He was bound in honour to fulfil his pledge to the royal cause by sending the thirty men, and as for himself, he had no hesitation in deciding that, for this night at least, the post of duty, if not of honour, was on the ramparts of his own castle, even though on that account the Singletons must ride leaderless to the king's standard. Besides, it must be confessed, there was a spice of adventure about the undertaking which well accorded with his bold spirit; and as his thoughts went back to the scene of the banquet and the suspicions entertained there as to his own courage, it pleased him to reflect that, whatever happened, a Singleton would never again be able to charge his chief with cowardice. It was nine o'clock and quite dark when he turned from the gateway out of which his men had just sallied, and retraced his steps slowly into the deserted castle. His solitary footsteps sounded weird and lonely across the paved yard which a few minutes before had rung with the clatter of horses and the bustle of preparation. Still more solitary did they sound as he passed on his way through the deserted passages, and found himself once more in the old banqueting-hall, where the feast remained still on the board, and the empty chairs all round, just as the clansmen had left them to obey the sudden and urgent order to march forth. But dreariest of all did they sound as, forcing open a small and long disused door, which grated back on its hinges and groaned as he did so, he stepped out on to the east terrace.
