Description: Gary finds himself back in the 1880s when Reg's grandfather was a policeman. Gary is to provide entertainment at the Royal Oak but only Marie Lloyd - who looks like Yvonne - finds him entertaining. There is a serial killer on the loose, none other than Jack the Ripper, and when Gary gets back to his shop he finds that Jack the Ripper, also a time traveller, has followed him through the portal. He reluctantly lets Jack go, only for Jack to get run over and killed. This is presumably why the Whitechapel murders ended when they did.
