THROUGH the dark night sky, streaking swiftly with their Hisso engines thundering, is the greatest trio of aces on the Western Front—the famous and inseparable “Three Mosquitoes,” the mightiest flying combination that had ever blazed its way through overwhelming odds and laughed to tell of it! Flying in a V formation—at point was Captain Kirby, impetuous young leader of the great trio; on his right was little Lieutenant “Shorty” Carn, the mild-eyed, corpulent little Mosquito and lanky Lieutenant Travis, eldest and wisest of the Mosquitoes on his left!

We’re back with the third and final of three Ralph Oppenheim’s Three Mosquitoes stories we’re featuring this march for Mosquito Month! And this one’s a doozy! Kirby and the boys stumble upon a German spy ring and find themselves in one of their most dangerous missions yet that takes them all the way to a face to face meeting with Kaiser Wilhelm himself! You don’t want to miss it—it’s a true group effort as Travis gets to shine in this tale from the pages of the July 1929 issue of War Birds—when the boys find themselves in”Enemy Air!”

Espionage! That sinister, silent net of war that caught men ruthlessly in its grip and crushed them. Now, in the innocent shape of a Fokker, it challenged insolently to those three sky warriors—the Three Mosquitoes. A story with a most thrilling and startling climax.
