The Surfing Corpse

P.C. and Mackenzie's junior class trip ends in disaster when practically all the kids witness classmate Timmy Warner plunge to his death over a 300-foot waterfall. But several months later, the class vice president swears that he's seen Timmy at Venice Beach, California. P.C. and Mackenzie follow a trail of clues that evolve from deception to abduction to a second murder - and a life-and-death chase along the cliffs of Malibu Canyon.
