I.M. Spooky

I.M. Spooky is a character that appeared and is mentioned in Double Down. He is the author of the Spineticklers books series.

Identity
It is unknown whether it's a pen name, and if it is, what the real name of the writer is, and regardless of whether it's his real name, it is unknown what the I and the M stand for. Even on the "about the author" section it just says that the publishers don't know much about I.M. Spooky except that he's a man and he's writing the next book. As such, when Greg and several of his classmates tried to write book reports about him, they failed. Greg supposes that if "I.M. Spooky" is his real name, he'd have to write scary books, and he thinks that if it is a pen name, he mustn't tell Rowley as Rowley wrote a letter to a "Mr Spooky".
