Board to Death

The undercover brothers, Frank and Joe Hardy, go undercover at a major
skateboarding contest in Venice, California to find out which competitor
is trying to kill off the competition--literally! The list of suspects
includes Dex Thom, a skilled skateboarder whose parents wanted him to be
a musical prodigy, the Pink Shadow, a girl of mystery, and her equally
secretive trainer, Mr. Miyagi, and the Wraith, a dark and brooding young
man. Will Frank and Joe solve the mystery before the killer discovers
their real mission--and eliminates them?!
