In Victorian London, Albert Wilkes returns home for tea four days after his funeral. While his shocked and terrified wife rushes to prepare it, Wilkes takes the family dog for a walk and is abducted. His kidnapping is witnessed by young pickpocket Eddie, who becomes embroiled, along with an assistant at the British Museum and a clergyman's daughter, in a deadly plot involving the fragments of a diary, a secret department at the British Museum, and a dinosaurlike creature roaming the streets.
