 On or about 26 May 1555 Dee was arrested, and he and his associates were later imprisoned.On 4 June the Privy Council sought information concerning Ferrers's own whereabouts.After this incident there is little trace of Ferrers, and no record that he was at court during Queen Elizabeth's reign, although he was appointed escheator for Bedfordshire and Buckinghamshire in 1562–3 and for Essex and Hertfordshire in 1566–7.
