G is for... Ghostmaker

A mysterious being whose origins are obscure, the Ghostmaker was the leader of a travelling fairground troupe known as the Night Circus, as they only ever performed after dark. They arrived unnoticed, and left just as mysteriously. In their wake they left a trail of missing people, all of whom had visited their sideshow entertainments. In the 1920's Captain Jack Harkness had investigated them, and even joined them for a time as "The Man Who Couldn't Die". They vanished for decades, but one night a young film buff discovered an old reel of film which contained footage of the troupe. The Night Circus were able to emerge from the celluloid onto the streets of present day Cardiff, and the Ghostmaker began to harvest people's life-force - leaving them comatose and dehydrated. He kept their spirits in a small silver flask. When he tried to attack Owen Harper, he was shocked to find that the Torchwood medic had no life to take, having recently been brought back from the dead.
Jack decided to use a film camera to recapture the Ghostmaker and his kin - destroying them when the film was then exposed to the light. However, the troupe lived on in other old film reels of their earlier appearances...
