In the midst of a terrible plague, young Robin becomes ill, but his symptoms are different from those of who contract the plague, and he loses the use of his legs. He becomes depressed, but a monk helps him slowly rebuild his life. He learns that, with effort, he can find his way out of nearly any difficulty.

Robin’s initial bout of paralysis takes place during one of the first plagues to strike London. His parents, Sir John and Lady Maud, are away in service to the king and queen. Death is everywhere, and soon there is no one at his home to help him. Robin feels angry despair. Help finally arrives in the form of Brother Luke, a monk who learned of Robin’s plight. He brings food, reassurance, and an important lesson: For every problem that stands before a person like a wall, “there will be a door in it” (16).

At first, Robin bemoans his condition and can’t imagine how it could improve. Brother Luke gently persists in his efforts to reveal future paths to him by giving him small projects to complete. He also introduces him to the other monks, and he takes Robin to a nearby river, where he teaches him to swim using his arms only.
