In May 1568
Mary, Queen of Scots fled to England, and flung herself on Elizabeth's protection. She had found refuge in
Carlisle Castle, and the delicate duty of taking charge of the fugitive was entrusted jointly to Knollys and to
Henry Scrope, 9th Baron Scrope of Bolton. On 28 May Knollys arrived at the castle, and was admitted to Mary's presence. At his first interview he was conscious of Mary's powerful fascination. But to her requests for an interview with Elizabeth, and for help to regain her throne, he returned the evasive answers which Elizabeth's advisers had suggested to him, and he frankly drew her attention to the suspicions in which
Darnley's murder involved her. A month passed, and no decision was reached in London respecting Mary's future. Knollys described her activities in letters to Elizabeth I, including watching two
football matches on a playing green outside the castle's
postern gate. On 13 July Knollys contrived to remove her, despite "'her tragical demonstrations", to
Bolton Castle, the seat of Lord Scrope, where he tried to amuse her by teaching her to write and speak English. Knollys's position grew more and more distasteful, and writing on 16 July to Cecil, whom he kept well informed of Mary's conversation and conduct, he angrily demanded his recall. But while lamenting his occupation, Knollys conscientiously endeavoured to convert his prisoner to his puritanic views, and she read the
English prayer-book under his guidance. In his discussions with her he commended so unreservedly the doctrines and forms of
Geneva that Elizabeth, on learning his line of argument, sent him a sharp reprimand. Knollys, writing to Cecil in self-defence, described how contentedly Mary accepted his plain speaking on religious topics. Mary made in fact every effort to maintain good relations with him. The gift was a chain of gold pomander beads strung on gold wire. In October, when schemes for marrying Mary to an English nobleman were under consideration, Knollys proposed that his wife's nephew, George Carey, might prove a suitable match. In November the inquiry into Mary's misdeeds which had begun at
York, was reopened at
Westminster, and Knollys pointed out that he needed a larger company of retainers to keep his prisoner safe from a possible attempt at rescue. In December he was directed by Elizabeth to induce Mary to assent to her
abdication of the Scottish throne. In January 1569 he plainly told Elizabeth that, in declining to allow Mary either to be condemned or to be acquitted on the charges brought against her, she was inviting perils which were likely to overwhelm her, and entreated her to leave the decision of Mary's fate to her well-tried councillors. On 20 January orders arrived at Bolton to transfer Mary to
Tutbury, where the
Earl of Shrewsbury was to take charge of her. Against the removal the Scottish queen protested in a pathetic note to Knollys, intended for Elizabeth's eye, but next day she was forced to leave Bolton, and Knollys remained with her at Tutbury till 3 February. His wife's death then called him home. Mary blamed Elizabeth for the fatal termination of Lady Knollys' illness, attributing it to her husband's enforced absence in the north. ==Relations with Elizabeth I==
