The England where the novel is set has to face from some years a great problem: ghosts apparitions that can kill with their touch.
The best in spotting and fight them are child and young adults, in fact they possess a certain sensibility that adults have no more, and they are able to locate the ghostly presences, someone by spotting some light effects, someone by hearing cries and voices.
The agency protagonist of the novel is the Lockwood & Co. formed by three children: Lockwood, who has a mysterious past, George, skilled in tracing historical information and Lucy, able to hear faint voices and the narrating voice of the novel. They have to deal with a murder case happened decades before and with the most terrible hunted house in the London area.
The novel is very engaging and well written, the events compose an interesting puzzle and some ghost apparitions are quite creepy; I will read for sure the following novel of the series.
* The Screaming Staircase by Jonathan Stroud ★★★★☆
