Cara was a Time Agent.
She inquired into records of Magnus Greel first at the Docks and then at his digs. She then found out about Li H'sen Chang. She was brutal in her methods. She went to the Palace Theatre to find more information about Chang and discovered that Henry Gordon Jago had booked his act. She came to the Red Tavern to find Jago and killed one of its regulars. She then tortured George Litefoot for information about Greel. She attacked Mrs Hudson, Litefoot's housekeeper. When she discovered that Magnus Greel was dead she was distraught because she couldn't kill him herself. Her vortex manipulator exploded and killed her. (AUDIO: The Stuff of Nightmares)
