La escalera de los gritos

Something strange is happening in London: all kinds of ghosts, apparitions, spirits and specters are appearing in the city, and they are not exactly friendly. Only the young have the psychic abilities necessary to see and defeat these supernatural dangers. Many psychic detection agencies have begun to sprout like mushrooms to stamp out this threat, and they compete with each other in this tough business. Fearless Lucy Carlyle teams up with Anthony Lockwood, the charismatic leader of Lockwood & Company, a small agency that operates without adult supervision. Both of them, together with their funny friend George, are forced to investigate one of the most famous and feared haunted houses in England. Will they manage to survive their legendary red room?
