The prior had obtained great credit by his character of sanctity; and he prevailed on the king again to grant a pardon to Perkin.

But in order to reduce him to still greater contempt, he was set in the stocks at Westminster and Cheapside, and obliged in both places to read aloud to the people the confession which had formerly been published in his name.
He was then confined to the Tower, where his habits of restless intrigue and enterprise followed him.

He insinuated himself into the intimacy of four servants of Sir John Digby, lieutenant of the Tower; and by their means opened a correspondence with the earl of Warwick, who was confined in the same prison.

This unfortunate prince, who had from his earliest youth been shut up from the commerce of men, and who was ignorant even of the most common Affairs of life, had fallen into a simplicity which made him susceptible of any impression.

The continued dread also of the more violent effects of Henry's tyranny, joined to the natural love of liberty, engaged him to embrace a project for his escape, by the murder of the lieutenant; and Perkin offered to conduct the whole enterprise.
The conspiracy escaped not the king's vigilance: it was even very generally believed, that the scheme had been laid by himself, in order to draw Warwick and Perkin into the snare; but the subsequent execution of two of Digby's servants for the contrivance seems to clear the king of that imputation, which was indeed founded more on the general idea entertained of his character than on any positive evidence.
Perkin, by this new attempt, after so many enormities, had rendered himself totally unworthy of mercy; and he was accordingly arraigned, condemned, and soon after hanged at Tyburn, persisting still in the confession of his imposture.[*] [1] It happened about that very time that one Wilford, a cordwainer's son, encouraged by the surprising credit given to other impostures, had undertaken to personate the earl of Warwick; and a priest had even ventured from the pulpit to recommend his cause to the people, who seemed still to retain a propensity to adopt it.
