Once upon a time Tubby Thackeray's silent comedies were hailed as the equal of Chaplin's and Keaton's, but now his name has been deleted from the history of the cinema. Some of his music-hall performances before he went to Hollywood were riotously controversial, and his last film was never released - but why have his entire career and all his films vanished from the record? Simon Lester is a film critic thrown out of a job by a lawsuit against the magazine he helped to found. When he's commissioned to write a book about Thackeray and restore the comedian's reputation, it seems as if his own career is saved. His research takes him from Los Angeles to Amsterdam, from dusty archives to a hardcore movie studio. But his research leads to something far older than the cinema, something that has taken a new and even more dangerous shape.
