There was not a sound heard in the mansion, which, at that moment, had no other occupants than the doomed prince, his two pages, (or chamber-cheilds as the Scots name them,) and five other attendants,—William Taylor, Thomas Neilson, Simpson, Edwards, and a boy. These occupied apartments at the extremity of the house, but on the same floor with the king. All the other attendants had absconded, to partake of the festivities at Holyrood, or had gone there in the queen's retinue.

"French Paris—Nicholas Hubert," said Bothwell in a husky voice, "the keys!"

Hubert produced them from beneath his mantle. They were a set of false keys which had been made from waxen impressions of the originals. The door was softly opened, and the conspirators entered the lower ambulatory, on each side of which lay a vaulted chamber.

Bolton thought of Hubert's sister, and his heart grew sick; for the brother knew not that his sister was at that time above them, in the chamber of Darnley.

"Come, Master Konrad," said Ormiston, tapping him on the shoulder; "if we are to be friends, assist us, and make thyself useful; for we have little time to spare."

Thus urged, Konrad, though still in profound ignorance as to the object of his companions, and the part he was acting, assisted Ormiston and French Paris to unload the sumpter-horse, and to drag the heavy mails within doors. These he supposed to contain plunder, and then the whole mystery appeared unravelled. His companions were robbers, and the solitary house, about and within which they moved so stealthily, was their haunt and hiding-place. With affected good-will he assisted to convey the mails into the vaults, where, some hours before, Hubert had deposited a large quantity of powder, particularly under the corner or ground stones of the edifice.

While they were thus employed, and while the ex-Lord Chancellor and Whittinghame kept watch, the Earl and John of Bolton ascended softly to the corridor of the upper story, where, by the dim light of a small iron cresset that hung from the pointed ceiling, they saw Andro Macaige, one of the king's pages, lying muffled in his mantle, and fast asleep on a bench.

"Confusion!" said the Earl fiercely; "this reptile must be destroyed, and I have lost my poniard!"

"Must both the pages die?" asked his companion, in a hollow tone.

"Thou shalt soon see!" replied the Earl, who endeavoured, by imitating Ormiston's careless and ruffian manner, to veil from his friends, and from himself, the horror that was gradually paralysing his heart.
