In honor of Agatha Christie's birthday today, we though we'd get our sleuth on with a little Blind Item P.I. to commemorate the famous mystery writer. Our story comes to us from BlindGossip.com, and involves a former child star who says he was done a disservice by his on-set tutor from his days on a famous '80's network sitcom. Apparently the tutor keeps the kids rested and happy by doing all of their work while they play video games or take naps, and she's still working in Hollywood. Sounds like the teacher I always wish I had, so why is this guy so bitter? let's do some investigating to find put which former child star could use a do-over with his elementary studies?
