What is a short summary of the story, The Ni**er Knockers, from the anthology, The World Doesn’t Require You?

The Ni**er Knockers is told from the perspective of Deez, a young man who lives in Cross River who begins playing the game Ni**er Knocker with his childhood friend, Tyrone James, who uses it as the subject of his dissertation. Their game playing in Port Yooga results in an innocent black teen getting beaten and mistakenly charged with mischief after locals believe its him who has been knocking on their doors. Tyrone feels guilty and admits his whole dissertation was a joke, but Deez cannot move on from believing the game to be important and the work to be incredible.
