107 Baker Street

107 Baker Street was a house in London which the Fifth Doctor owned and lived in from November 1866 to November 1867. (AUDIO: The Haunting of Thomas Brewster) The house had a secret cellar, a priest hole and a larder. (AUDIO: The White Room)

In 1894, Professor Claudius Dark told his friends Henry Gordon Jago & Professor George Litefoot to go to the house dressed as the fictional characters Sherlock Holmes and John Watson. There they met the creator of the characters, Arthur Conan Doyle, who had been told where to meet the investigators by Professor Dark. (AUDIO: The Monstrous Menagerie)

In 1918, Molly O'Sullivan stayed in Baker Street after leaving the front lines. After she left with the Eighth Doctor, Molly gave David Walker the keys to the house. (AUDIO: The White Room) David lived in the house until the 1970s. (AUDIO: Eyes of the Master)

Due to the interventions of Kotris, (AUDIO: Eyes of the Master) by 1970, the house was the base of the Ides Scientific Institute. In 1972, the Eighth Doctor visited Baker Street. Shortly after the Doctor arrived, a time-space portal opened and Daleks came through, chasing the Doctor, Molly O'Sullivan and Sally Armstrong from the property. (AUDIO: Fugitives) The Ides Institute was no longer located in Baker Street after Kotris had been erased from history. (AUDIO: Eyes of the Master)

From 2008 to 2010, Thomas Brewster lived in the house, which was given to him by the Doctor as a present. (AUDIO: A Perfect World, AUDIO: The Crimes of Thomas Brewster)
