Paperback - Kids are getting sick after lunch . . . and it's not because of questionable cafeteria food. It's poison! But there are only two groups tossing their cookies: the super-cool girls and the comic book buffs. Who would hold a grudge against such opposite cliques, and why would they want to poison them? When there's a school mystery that needs solving, the S.M.A.R.T.S. are ready to put their sharp minds to the test! It will take their best critical-thinking skills and scientific reasoning to get to the bottom of this lunch period puzzle.
