Cheke went on to serve as a tutor to Edward VI (1544) and Secretary of State for Lady Jane Grey, during her very short reign in July 1553. He was imprisoned in the Tower of London by Mary I for his part in Lady Jane Grey's "usurpation" of the throne, but released just over a year later. Cheke then travelled to the continent but was arrested between Brussels and Antwerp in Spring 1556, along with Sir Peter Carew, and taken back to England, where he was once again imprisoned in the Tower. In fear of being burned at the stake for his Protestant beliefs, he agreed to be received into the Catholic Church and was released from prison in October 1556 after making a public recantation in front of Mary I. Afterwards, he was ashamed of himself and regretted his cowardice. He died just over a year later, on the 13th September 1557.
