This book is about Dink、Josh and Ruth Rose,three kids went to Wallis Wallace’s castle.They found that there’s a screaming sound in the castle,and one trapdoor that led to a tunnel.Josh thinks it’s a dungeon that Emory Scott died.Emory Scott is a movie star that build this castle in 1930s. This book is pretty scary, but at the end,they found out it was only some parrots screaming in the tunnel,but why would a parrot be in a cave?Soon,they discover that a man called Ripley Pearce did it. I think this story is quite scary.But I still love this book.
