We have been looking at the images left at a publisher's office by a man called Harris Burdick. Harris left a set of black and white images (with a title for the accompanying story) for publishers to look over. He was due to return the following day to discuss turning them into a book, but never returned. We had a go at writing what we thought the story might have been and worked really hard on using descriptive language to set the scene.
