<CENTER><B>IT'S A DIRTY SHAME!</B></CENTER> <P> Misty's younger brother left her brand-new bike in the middle of the street, and a speeding car ran over it. Not only is the bike totally mangled, it's covered with ugly red dirt. <P> Misty wants to find the driver, but she doesn't have much information to go on -- all she noticed was that the car was white. The Third-Grade Detectives agree to help, but there are an awful lot of white cars around town. Can the detectives clean up the case?
