Things seem to be looking up when the team is called to Kensal Green Cemetery to investigate the grave of a sinister Victorian doctor. Strange apparitions have been seen there, and the site must be made safe. As usual, Lockwood is confident; as usual, everything goes wrong - a terrible phantom is freed and a dangerous object is stolen from the coffin.

Lockwood & Co. must recover the relic before its power is unleashed, but it's a race against time. Their obnoxious rivals from the Fittes agency are also on the hunt.

And if that's not bad enough, the skull in the ghost-jar is stirring again.
