Sir Thomas Cooke was one of the most reputable citizens of London, and, in the second year of Edward's reign, had fulfilled the highest municipal functions. Unfortunately for him, also, he had the reputation of being so wealthy as to tempt plunder. Earl Rivers and the Duchess of Bedford appear to have thought so; and exerted their influence with the king to have the ex-mayor arrested on a charge of treason, and committed to the Tower. It appears that, in an evil hour for Cooke, a man named Hawkins had called on him and requested the loan of a thousand marks, on good security; but Sir Thomas said he should, in the first place, like to know for whom the money was, and, in the second, for what purpose it was intended. Hawkins frankly stated it was for the use of Queen Margaret; and Cooke thereupon declined to lend a penny. Hawkins went away, and the matter rested for some time. Sir Thomas was not, however, destined to escape; for Hawkins, having been taken to the Tower and put to the brake, called "the Duke of Exeter's daughter," confessed so much in regard to himself that he was put to death; and at the same time, under the influence of excessive pain, stated that Cooke had lent the money to Margaret of Anjou. The Woodvilles, having obtained such evidence against their destined victim, seized upon Cooke's house in London, ejecting his lady and servants, and, at the same time, took possession of Giddy Hall, his seat in Essex, where he had fish-ponds, and a park full of deer, and household furniture of great value. After thus appropriating the estate of the city knight, they determined that, for form's sake, he should have a trial; and accordingly a commission, of which Earl Rivers was a member, was appointed to sit at Guildhall. It would seem that the Woodvilles, meanwhile, had no apprehension of the result being unfavorable to their interests; but, unfortunately for their scheme of appropriation, the commission included two men who loved justice and hated iniquity. These were Richard Neville, Earl of Warwick, and Sir John Markham, Chief Justice of England.
