Help! A series of outrageous crimes must be solved--and only someone with superior math and logic skills can do it. That meansyou, right? Count on an exciting time when you join law enforcement's finest--Midville Police Chief Arthur Smart and 12-year-old junior detective Cal Q. Leiter--as they uncover scam artists, catch vandals, nab hit-and-run drivers, and unravel many more mysteries. Just remember: numbers are the key to unlocking the answers! How much money did Gertrude Gessler leave in her will to divide among her four nephews? What tricks did the carnival vendor use to cheat the Chief's cousin in a game of luck? Who vandalized the Mayor's office while she was away--and how can you prove it with arithmetic? What are the odds you can figure these out? Pretty good--if you read carefully and think hard, the facts all add up.
