Great Eastern Street

Great Eastern Street was a street in Shoreditch.

It was not far from the house of Charlie Smith and Miss Quill. John O'Donnell was running along Great Eastern Street in Ram Singh's body when their body swap was reversed. (PROSE: Joyride)

Behind the scenes
Although not stated in the novel explicitly, it can be inferred that Great Eastern Street is in Shoreditch because O'Donnell goes from 1 Wellington Road, which is in Shoreditch to Swallow Avenue, which is also in Shoreditch via Great Eastern Street.
