Milo Tindle has been invited to Cloak Manor to meet with Andrew Wyke, noted author of detective novels. He spends a good deal of time trying to solve Andrew's labyrinth, only to discover that there is a trick involved.

The scene gives Milo (and the viewer, if they're paying attention) the first clue that Andrew is devious and full of tricks himself.
