Books in Puzzle series

Fire up the brain—a mystery needs solving and smart young sleuths can help! It’s happening at the Riddle Middle School, where a group of suspended students hacked into the computer and stole the big midterm exam. Now, the mischief makers threaten to give the test to everyone unless the principal drops their punishment. Instead, the principal orders the six department heads to find the culprits or face demotion. Join forces with the faculty and new pupil Rodman as they search for the thieves, and along the way take brainteasing challenge after challenge—including lateral thinking puzzles, tricky logic questions, and mathematical conundrums—to capture the crooks. Of course, all the solutions are right in the back of the book, thoroughly explained.
