The Screaming Staircase

"Three kids who run a professional ghost hunting company have been hired to investigate a house that’s so haunted and dangerous, no other team has ever made it out alive. If you’re into gripping and suspenseful ghost stories mixed with dry humor, this book is for you. (Bonus points if you also like murdered monks and walls dripping with blood.) (For ages 8 to 12)"

"I’ve chosen him because he’s one of the most magnetic characters that I’ve come across in detective fiction. He is the leader of a group of ghost hunters called Lockwood & Co, and he is someone who you absolutely believe anyone would be completely charmed and bowled over by—as the main character, Lucy is when she joins Lockwood & Co. Lockwood & Co is set in a world where ghosts are real and walk among us. Hauntings are becoming daily more dangerous—and deadly. Only children can see ghosts, so children become the most important people in this world. They all form ghost-hunting squads to keep the adults safe from danger. Lockwood & Co is the smallest ghost-hunting organization in London, but the most brilliant, obviously! There are five books in the series, and each one is like a murder mystery. The team are dealing with ghosts, but of course each ghost was created by a terrible crime in the past. What Lockwood & Co need to do in each story is work out how the ghost was created, and how to lay them to rest. They do this by basically solving the crime—they are murder mysteries with a supernatural twist. More kids’ books recommendations on Five Books"
