简要：When John "Ludwig" Taylor's identical twin, DCI James Taylor, disappears from Earth, John takes over his brother's identity and tries to find his whereabouts. John has never been married; He has never had a family and has never really left his home. Without a computer, phone, or even TV, he lived a quiet and lonely life, making a living by designing puzzles and using the pseudonym "Ludwig". This curved detective series tells the story of full-time Lutetian John "Ludwig" Taylor, who disguises himself as a missing twin brother in an attempt to find him and bring him home. However, replacing your identical twin is one thing - the risk is much higher when your twin happens to be a successful DCI leading a major crime team in the busy city center of Cambridge. John may be the master of all mysteries, but can he solve the biggest puzzle of his life?
