Context
Lamb's Conduit Street runs through Holborn, in central London. By 1921 it already had a history with the unseen. On 3 June 1871 the medium Agnes Guppy was allegedly carried from her home in Highbury to a séance table in this street. Spiritualists, including Arthur Conan Doyle, called it genuine, and sceptics called it a hoax. Fifty years on, a 1921 magazine still described the street as "the residence of another notorious medium".
