I read this book when I was very young, then buried it in the garage for six years. It is roughly 2nd-3rd grade level, and a very cute and age-appropriate thriller for adventurous young readers. I highly reccommend it.
What is the matter with Mr. Frank, the man who has moved into Sam and Robert's building? Why is he so nasty Why does he use so much electricity? And what are those odd moans and groans coming from his apartment?
Sam and Robert think they know the answer. Together they reread one of Sam's horror books. Just as they thought, there are an awful lot of similarities between Mr. Frank and the man in the story. Too many to be just a coincidence.
Could it be true? Is Grankenstein really living on the fourth floor of their building? Sam and Robert aren't sure, but they're determined to find out!
