Whatever truth there may be in this old tradition, there is every reason to believe that some of the worst tragedies recorded in family history have been due to jealousy; and an extraordinary instance of such unnatural feeling was that displayed by the second wife of Sir Robert Scott, of Thirlestane, one of the most distinguished cadets of the great House of Buccleuch. Distracted with mortification that her husband's rich inheritance would descend to his son by his first wife, she secretly resolved to compass the destruction of her step-son, and determined to execute her hateful purpose at the festivities held in honour of the young laird's twentieth birthday. Having taken into her confidence one John Lally, the family piper, this wretched man procured three adders, from which he selected the parts replete with the most deadly poison, and, after grinding them to fine powder, Lady Thirlestane mixed them in a bottle of wine. Previous to the commencement of the birthday feast, the young laird having called for wine to drink the healths of the workmen who had just completed the mason work of the new Castle of Gamescleugh—his future residence—the piper Lally filled a silver cup from the poisoned bottle, which the ill-fated youth hastily drank off. So potent was the poison that the young laird died within an hour, and a feeling of horror seized the birthday guests as to who could have done so foul a deed. But the father seems to have had his suspicions, and having caused a bugle to be blown, as a signal for all the family to assemble in the castle court, he inquired, "Are we all here?"

A voice answered, "All but the piper, John Lally!"

These words, it is said, sounded like a knell in Sir Robert's ear, and the truth was manifest to him. But unwilling to make a public example of his own wife, he adopted a somewhat unique method of vengeance, and publicly proclaimed that as he could not bestow the estate on his son while alive, he would spend it upon him when dead. Accordingly, the body of his son was embalmed with the most costly drugs, and lay in state for a year and a day, during which time Sir Robert kept open house, feasting all who chose to be his guests; Lady Thirlestane meanwhile being imprisoned in a vault of the castle, and fed upon bread and water. "During the last three days of this extraordinary feast", writes Sir Bernard Burke,[16] "the crowds were immense. It was as if the whole of the south of Scotland was assembled at Thirlestane. Butts of the richest and rarest wine were carried into the fields, their ends were knocked out with hatchets, and the liquor was carried about in stoups. The burn of Thirlestane literally ran with wine." Sir Robert died soon afterwards, and left his family in utter destitution, his wife dying in absolute beggary. Thus was avenged the crime of this cruel and unprincipled woman, whose fatal jealousy caused the ruin of the family.

Political intrigue, again, has been the origin of many an act of treachery, done under the semblance of hospitality, or given rise to strange incidents.

To go back to early times, it seems that Edward the Confessor had long indulged a suspicion that Earl Godwin—who had in the first instance accused Queen Emma of having caused the death of her son—was himself implicated in that transaction. It so happened that the King and a large concourse of prelates and nobility were holding a large dinner at Winchester, in honour of the Easter festival, when the butler, in bringing in a dish, slipped, but recovered his balance by making adroit use of his other foot.

"Thus does brother assist brother," exclaimed Earl Godwin, thinking to be witty at the butler's expense.

"And thus might I have been now assisted by my Alfred, if Earl Godwin had not prevented it," replied the King: for the Earl's remark had recalled to his mind the suspicion he had long entertained of the Earl having been concerned in Prince Alfred's death.

Resenting the king's words, the Earl holding up the morsel which he was about to eat, uttered a great oath, and in the name of God expressed a wish that the morsel might choke him if he had in any way been concerned in that murder. Accordingly he there and then put the morsel into his mouth, and attempted to swallow it; but his efforts were in vain, it stuck fast in his throat—immovable upward or downward—his respiration failed, his eyes became fixed, his countenance convulsed, and in a minute more he fell dead under the table.

Edward, convinced of the Earl's guilt, and seeing divine justice manifested, and remembering, it is said, with bitterness the days past when he had given a willing ear to the calumnies spread about his innocent mother, cried out, in an indignant voice, "Carry away that dog, and bury him in the high road." But the body was deposited by the Earl's cousin in the cathedral.

Several accounts have been written of that terrible banquet, to which the Earl of Douglas was invited by Sir Alexander Livingstone and the Chancellor Crichton—who craftily dissembled their intentions—to sup at the royal table in the Castle of Edinburgh. The Earl was foolhardy enough to accept the ill-fated invitation, and shortly after he had taken his place at the festive board, the head of a black bull—the certain omen, in those days in Scotland, of immediate death—was placed on the table. The Earl, anticipating treachery, instantly sprang to his feet, and lost no time in making every effort to escape. But no chance was given him to do so, and with his younger brother he was hurried along into the courtyard of the castle, and after being subjected to a mock trial, he was beheaded "in the back court of the castle that lieth to the west". The death of the young earl, and his untimely fate, were the subjects of lament in one of the ballads of the time.
