T3, E3: A forged cablegram summons Jill to highspeed adventure. Continental charmer Paul Ferrino, Jill's old flame, persuades her to drive his experimental car in the Grand Prix. A good showing could bring needed research funds. A garage explosion spells trouble. The car and mechanic Danny Bligh are scheduled for minor repairs, and the Angels begin some high gear sleuthing. Suspicion rests on Jill's fiancée Steve Carmody, who apparently has some old scores to settle with Paul. Steve impulsively takes the car for a spin and dies in an explosion. A clandestine meeting between Danny and jaded socialite Andrea Lassiter leads the Angels to discover the real culprit, Ferrino himself, whose car is a lemon. Jill shudders to think that in his desperate attempt to recoup his losses, he had ticketed her for death.
