Traitor's Road — Dorothy Daniels

SPIES AT SPEED.

Joyce Bowen followed her heart to Europe. She could not believe that Alex Linhart no longer loved her; she refused to accept his statement that his life as a racing-car driver was too dangerous to allow him to marry. Her own love was as strong as ever -- and she knew that it could conquer all obstacles. She did not dream of how many obstacles there actually were -- or how sinister their nature. The facts dawned gradually, as she found Alex enmeshed with a strange, furtive group of people. Then her passport was stolen, and she realized that she had become the target of implacable though unseen enemies. And finally the ugly pattern of espionage began to emerge. The shock of knowing that the roar of racing engines can be a cover for a vast spy plot was a great one -- but there were greater shocks to come!
