A powerful invasion of otherworldly visitors is baffling the police and sparking protests across London. There are reports of new ghosts appearing, such as bloody footprints on the stairs or strange sounds and ghostly figures in a department store. The Lockwood & Co. agency continues to demonstrate its skill in neutralising spirits. At the same time, Lucy Carlisle is under real stress when Lockwood and George introduce her to their new assistant, the overly tidy and diligent Holly Munroe... Will their team be able to move past their personal feelings? Or will the bad feelings only cause them unnecessary trouble? Danger is looming, tension is rising, and the relationship between the characters is moving to a new level - all this in the eerie and interesting third part of the Lockwood & K Agency series.
