In a London made only of records, the great clock has stopped one second before midnight. Each time the night rewinds, the observer Charlotte Holmes loses another letter of her name. At 221B Baker Street, the record persona of Sherlock Holmes tells her of an observer who came before her — a story no one finished writing. To end the endless night, Charlotte must face Jane, the phantom thief who keeps the stolen second, and decide what she is willing to pay with her own name.
