A sinister problem has occurred in London: all nature of ghosts, haunts, spirits, and specters are appearing throughout the city, and they aren't exactly friendly. Only young people have the psychic abilities required to see - and eradicate - these supernatural foes. Many different Psychic Detection Agencies have cropped up to handle the dangerous work, and they are in fierce competition for business.

After an assignment leads to both a grisly discovery and a disastrous end, Lucy, Anthony, and their sarcastic colleague, George, are forced to take part in the perilous investigation of Combe Carey Hall, one of the most haunted houses in England. Will Lockwood and Co. survive the Hall's legendary Screaming Staircase and Red Room to see another day?
