Life is never exactly peaceful for Lockwood & Co. Lucy and George are trying to solve the mystery of the talking skull trapped in their ghost jar, while Lockwood is desperate for an exciting new case. 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 unleashed, and a dangerous object is stolen from the coffin.
