In 1889, the Fourth Doctor treated Leela to an evening at the Palace Theatre which included singing and a conjuring act by Li H'sen Chang with his sidekick Mr Sin. The Doctor had hoped to see Little Tich.
Finding a link between missing women, including Emma Buller, and the theatre, they enlisted the help of the theatre's manager and master of ceremonies, Henry Gordon Jago. Chang had secretly used the cellar of the theatre as a temporary base of operations, using a hologram of a ghost to scare away intruders. (TV: The Talons of Weng-Chiang)
