Venerable John Mason was a servant to Mr. Owen of Oxfordshire. When Topcliffe endeavoured to obtained entry in to the room where Father Gennings was saying Mass, Mason seized him, and in the struggle both fell down the stairs together. Mason was therefore cited as an aider and abettor of priests and condemned accordingly.
