<B><CENTER>IT'S DO OR DIE FOR THE THIRD-GRADE DETECTIVES!</CENTER></B> <P> Todd and Noelle are volunteering at a blood drive when they get shocking news: Both banks in town have been robbed! This may be the Third-Grade Detectives' most important case yet. The new police chief doesn't think he needs help from a bunch of third graders to solve crimes, and if the kids can't prove him wrong, their detective careers may be over. <P> The trouble is, the thief hasn't left any clues, except for a discarded sweaty handkerchief. Yuck! Can something so disgusting provide the lead the Detectives need?
