Bridget Spears

Personal assistant to Home Office Permanent Secretary John Frobisher, and immensely devoted to him – they have actually worked together for thirty years. She gave Lois Habiba her username and password so Lois could assist with the mounting work in the office, but Lois used it to find out who Captain Jack Harkness was. After John Frobisher told Bridget about the 456, he gave her a file with a blank piece of paper in it. Spears knew what it was and drew up orders for four people to be killed, one of whom was Jack.
