Having thus made up his mind on the propriety of bettering his condition, and having reconciled his conscience to the betrayal of his friend, by assuming that, as Reginald would, one day or other, be infallibly taken prisoner and executed, it was much better, although it might shorten his life a few weeks or months, that a friend rather than a stranger should get whatever recompense was to be got. Indeed, if any scruples still lurked in his breast, his duties as a citizen at once put an end to them, for, as he said, "a true patriot must sacrifice every private feeling to the public good." Influenced by these mixed considerations, he applied for, and obtained a promise, if he should be able to surprise the Tower of Gloom and its proprietor, that he would be rewarded with a gift of the forfeited estate of Inshannock.

Having made every arrangement, in the event of success, Donald Campbell, with a body of retainers, proceeded to the Tower of Gloom. Hiding his followers in a copse of wood in the immediate vicinity, Donald hastened to the abode of his friend, and, claiming his hospitality, was readily admitted as an inmate. The result may be easily anticipated: Reginald found himself a prisoner, for the first time in his life. Resolved rather to perish than surrender, the unfortunate laird ran to an apartment overlooking the loch, and leaped from the window into the water. His false friend, seeing his desperate efforts, threw him a rope as if in kindness, to support him, while a boat came near.

"That rope was meant for my neck, and I leave it for a traitor's," were the last words that came from the lips of the betrayed one.

The pangs of remorse penetrated the heart of the insidious Campbell. He leaped himself into a boat, held out an oar toward his drowning friend, with real oaths of fidelity; but Reginald pushed it from him, and abandoned himself to death. The waters of the lake are singularly transparent near the rock on which the Tower of Gloom was perched; and Campbell beheld his victim gradually sinking, till he seemed to lie among the broad weeds under the waters. Once, only once, he saw, or thought he saw, him lift his hand as if to reach his; and that dying hand never left his remembrance.

Campbell having thus successfully accomplished the enterprise he had projected, applied for and obtained the reward he had stipulated for. He received a grant of the lands of Inshannock; and the long-wished-for Tower of Gloom came into his hands, together with the sum of money offered for the capture or death of Reginald. So far, therefore, as worldly matters went, Donald Campbell, Esq. of Inshannock, had no cause to complain. But he was far from happy, for he could not but reproach himself with the death of one who, trusting to his honour, had been basely betrayed; and those reasons of expediency which had satisfied him when he contemplated the deed, after its accomplishment lost all their previous efficacy. He had another and separate cause of distress; his only son, Roderick, a promising youth, above sixteen years of age, had suddenly disappeared in the year 1745, and no traces of him whatever could be found. Every effort had been made to discover his fate, but in vain; thus, although Donald Campbell was, apparently, a man of opulence, he was in reality a much less happy man than when he lived from hand to mouth, and knew not one day where he was to look for provision for the next.

Although this enterprise had been successful, Campbell did not reap all the fruits of his perfidy; for some of the remote portions of the Highland estate which he had procured a gift of from the crown, were altogether unproductive, the tenants refusing to recognise any other chief than the son of the deceased proprietor. William Grahame was, at the time of his father's death, a boy of fifteen. He had been removed from the Tower of Gloom by his mother's relations, about the time of the suppression of the rebellion, and placed by them in the Marischal College in the city of Aberdeen.

The lad, who had no great taste for classical literature, was by no means comfortable, and longed to return to the purple heath of his native hills. So long as his father lived, William behaved himself with considerable propriety, and made some progress in his studies; but no sooner did the tidings arrive of the untimely fate of the ill-starred Reginald, than his son disappeared from the university, and the anxious search of his friends was unable to obtain any traces of his flight. Some time afterwards, a body was found in the river Dee, in a state of great decomposition, which generally was supposed to be that of the young man, and was duly interred as the corpse of the last Grahame of Inshannock.

Time hurried on; and the new proprietor of Inshannock had begun to feel the effect of its rapid transit: he was no longer the vigorous man of forty; and as he passed towards the period of threescore, the effects of age told severely upon him.

For a series of years, Donald Campbell had been very much exposed to the depredations of a set of caterans or gipsies, who frequently kept him in a state of siege in his tower.

This tower was of the true Scottish fabric, divided into three storeys: the highest of which contained the dormitories; the second or middle served as a general refectory; and the lowest contained his cattle, which required this lodgment at night, or very few would have been found next morning.
