Page "Susan Foreman" Paragraph 5

The Doctor and Susan had already been travelling for an unspecified amount of time, before they decide to settle in London to make repairs on the TARDIS ; Susan states that she and her grandfather have been in London for five months.

Susan also alludes to several previous adventures to Ian Chesterton and Barbara Wright in the course of their shared adventures ; both on various alien planets and on Earth in various past time periods ( such as encountering a wrathful King Henry VIII ).

Susan begins to attend the Coal Hill School in Shoreditch, where her advanced knowledge of history and science attract the attention of schoolteachers Barbara and Ian.

Attempting to solve the mystery of the " unearthly child ," Ian and Barbara follow Susan back to the junkyard, where they hear her voice coming from what appears to be a police box.

When they investigate further, they discover that the police box exterior hides the much larger interior of the TARDIS, and are whisked away on an adventure in time and space with the Doctor and Susan, against their will.
