It was rumoured that the Duke of Northumberland, anticipating want of money to pay the forces which would be required in the event of his daughter-in-law Lady Jane Grey being proclaimed queen, gave a large sum to Fisher's keeping, which was hidden by him in Bishop's Itchington pool.
Fisher represented Warwick in the second parliament of Mary, 1554, and in the first (1554), second (1555), and third (1557-8) of Philip and Mary.
