The Shadow on the Stairs

What it says on the back of the book

"He was cold and shaking all over. He closed his hands into his fists so his fingernails were digging into his palms, but he couldn't stop the shaking..."

People say Joe's new house is haunted. Every night, he looks for the shadow on the attic stairs. Sometimes he thinks he can see it, sometimes he knows he can't. He tells himself that he isn't scared and wishes he could get the idea that it is evil and out of his mind. But he never suspects that something much worse than seeing a strange shadow is about to happen...
