Dave Dawson at Casablanca

A young aviator named Dave Dawson undertakes a covert wartime air mission from the United States to Natal, Brazil, with stops in Miami, Puerto Rico, Trinidad, and Dutch Guiana, delivering heavily sealed, waterproof envelopes to American officers and instructed to keep them unopened until a specified date. The assignment blends routine transport and formal protocols with escalating danger as enemy snoopers, aerial attacks, sabotage, and altered orders threaten crew and cargo. The narrative alternates tense briefings, guarded airfields, and night operations, paying attention to aircraft procedures and combat action, and follows a sequence of episodic missions and confrontations that test loyalty, courage, and the imperative to protect the secret consignments.
