Freemason
From Tardis Wiki, the free Doctor Who reference
The Freemasons were a secret organisation. A message left on a wall led the police in 1888 to suggest that Jack the Ripper was a member of the group. (PROSE: The Pit) The Goulsten Street message's reference to "the Juwes" actually had nothing to do with the group. Chief Inspector Smith believed "Sir Charles Warren" had connections to the Freemasons when he ordered the message removed. (COMIC: Ripper's Curse) In the 1740s, Magdalen College was considered to be a magnet for those with Masonic connections. (PROSE: The Adventuress of Henrietta Street)
