Uncle Sam Quarterly #8

Uncle Sam and his pal Buddy travel the nation hunting saboteurs, and their latest quarry is Blackout—a cunning villain who strikes only under cover of test blackouts, using the darkness to damage America's war production. When Blackout targets the Brooklyn Navy Yard and later an aircraft factory in Detroit, Uncle Sam must outthink an enemy who vanishes into shadow, armed only with a schedule of coming blackouts and his unshakeable determination to stop him.

When a mysterious force destroys an entire squadron of RAF bombers over the Channel—planes that never even reach their target—Uncle Sam joins forces with the British to uncover a sinister Nazi plot. As assassination attempts pile up against Lieutenant Gray, Uncle Sam realizes the answer lies in the sabotaged aircraft themselves, and he'll have to stop a bombing run mid-flight to prove it. With the Daredevil Squadron's next mission hanging in the balance, Uncle Sam races to expose the enemy agents embedded in their own ranks before another flight is lost.
