Into Thin Air

Nancy sizes up a sky-high
case of murder — with
explosive results

George’s neighbor Mark Rubin has been canned by his detective agency. J. Christopher Johnson, subject of an embezzlement investigation, has vanished in a helicopter crash — and Mark’s boss blames him for blowing the case. But Mark is convinced that with Nancy’s help he can blow the case wide open! He claims Johnson is still alive!

Was the crash an accident? Was it murder? Or was it all a masquerade? Nancy’s getting close to the truth, maybe too close for comfort. The mystery of Christopher Johnson’s fate has become a question of life and death… for Nancy Drew!
