A Victorian Interlude

With giant rats still roaming the sewers of Victorian London, Henry Gordon Jago and George Litefoot realise that someone must deal with the creatures and intend to do it themselves using their newly acquired Gatling gun. They have only been told about the rats by the Doctor, and have not actually seen them. As the pair leave the public house where they have been discussing their forthcoming task, as well as wishing the Fourth Doctor was still around to help, Litefoot bumps into a stranger dressed as a cricketer, to whom he apologises before departing. While the stranger seems to recognise him, Litefoot feels a chill pass through him.
