Ring the door bell and wait

After a few minutes waiting, during which you really hope that nobody will walk past who knows the building, you see a shape moving inside.

A woman comes to the door, casually dressed in jeans and a fleece. "Come inside..." she brings you out of the sun and slightly into the cool of the building, shutting the door behind you.

You start to look around - there is an empty room just inside the door that looks like it is being decorated, and has a good view of the street.

The woman pushes past you again, but her movements were just to distract you. Turning you to face the door of the empty room, she lightly shoves you forward into the room.
