suspected of misprision (having knowledge of the plot but not notifying the authorities). However, the Star Chamber did not have sufficient evidence to convict him of misprision and was unable to disprove his claim that he planned to be present at the fatal meeting of Parliament. They had to resort to more minor charges including his appointment of Thomas Percy to the Gentlemen Pensioners, of which Northumberland was captain, without the king's permission and without Percy taking the Oath of Supremacy. Northumberland was sent to the Tower of London at the king's pleasure and remained there for almost 16 years. He was also fined £30,000, , but in 1613, the king accepted £11,000 in final payment. In the Tower Still a rich man, Northumberland made himself comfortable in the Tower of London. He had spacious apartments in the Martin Tower, which he redecorated and refurbished. He was attended by 20 servants, some of whom he lodged on Tower Hill. He spent £50 per year on books and grew a considerable library. He had his own covered bowling alley and access to facilities for tennis and fencing. He regularly met scholars whom he patronised, including Thomas Harriot, Walter Warner and Robert Hues, who were known as the "Earl of Northumberland's Magi." Together with Sir Walter Raleigh, who had preceded Northumberland to the Tower with a death sentence hanging over him, they discussed advanced scientific ideas and smoked tobacco. From 1616, Robert Carr, 1st Earl of Somerset and Frances Carr, Countess of Somerset were inmates of the Tower and on social terms with Northumberland. Frances promoted the marriage of his second daughter Lucy Percy to James Hay, 1st Earl of Carlisle. He disapproved of the proposed marriage saying that he would not see his daughter, "dance to a Scotch jig." For a period, he forced Lucy to reside with him in the Tower but Frances outwitted him. Despite Northumberland's extreme disapproval of the marriage, Hay was determined to win his father-in-law's respect and fought for Northumberland's release from the Tower, which was achieved in July 1621. After his release, experiencing deafness and poor eyesight, he went to the Bath Inn, later referred to as the Arundel House, to regain his health. Once recovered Northumberland retired to Petworth House where he remained until his death on 5 November 1632. His wife died in 1619. Intellectual interests and associates Because of his interest in
