Book questions!

Ok so here the thing I recently watched flower in the attic on Netflix because I was bored and I ended up making the movie but now I find out they did a remake and that it’s also a book and I’m starting to wonder if it worth getting my self into this?

SCARY!

So I always hear walking in my attic but no one up there and my attic is locked and we don’t even have a key to open it O_o and all I ever seen in there is a baby doll
