Jack (called Noseeum Jack because he was blind) is a character from the Beyond the Spiderwick Chronicles series. He was a giant hunter who was blind but only saw giants and monsters since having the seeing made him see better. His father, before him was a giant hunter, who wrote letters to Arthur Spiderwick. Jack first appears near the end of Book One: The Nixie's Song, where he kills a giant that was attacking Laurie, Nick, and Jared. During the events of A Giant Problem he has a leg injury and can't fight giants anymore so he retires. Because he was old and decrepit he had to go live with his son, Jack Jr who was a lawyer and his wife. After Nick defeated the Wyrm king in Book Three: The Wyrm King, Noseeum Jack said he was proud and that they were real heroes just as he had been in the old days.
