Synopsis from Goodreads

A Problem has occurred in London: all nature of ghosts, haunts, and spirits are appearing throughout the city, and they aren't exactly friendly. Only young people have the psychic abilities required to see - and, hopefully, eradicate - the supernatural enemies. Many different Psychic Detection Agencies have cropped up to handle the dangerous work, and they are in fierce competition for business. In THE SCREAMING STAIRCASE, the plucky and talented Lucy teams up with Anthony, the leader of Lockwood & Co, a small agency that runs independent of any adult supervision. After an assignment leads to both a grisly discovery and a disastrous end, Lucy, Anthony, and their wise-cracking colleague, George, are forced to take part in the perilous investigation of one of the most haunted houses in England: Combe Carey Hall. Will Lockwood & Co. survive the Hall's legendary Screaming Staircase and Red Room to see another day? How did the Problem originate, and how can it be solved?
