George’s fling at racing
draws Nancy
into a freewheeling mystery
When Nancy’s friend George decides to take up bicycle racing — coached by her boyfriend, Jon — she becomes the target of some nasty attacks. After she’s run off the track at high speed, Nancy steps in to help and manages to keep George from being hurt in a swimming “accident.”
At first Nancy’s top suspect is George’s romantic rival, Debbi. But the teen detective soon finds that the attacks on George are just the tip of the iceberg. Underneath lies the secret of a perfectly planned robbery — and a million-dollar treasure guarded by a killer shark.
