Book excerpt: Dr. Quicksolve can crack any crime in record time, and his son Junior is following in his footsteps. Learn how they rapidly solve robberies, identify forgeries, capture crazed fans, and track down other criminals--like the bad guys who poisoned the ink in the pen used to sign a merger, or the thieves who carried out the cookie jar caper. Figure out the fun tricks, too, like the one Junior's twin cousins Flora and Fauna like to play on him whenever they get the chance. Remember that things aren't always what they seem, so think carefully and work quickly if you want to keep up with these smart pros!
