Their familiar war cry rings out—“Let’s Go!” The greatest fighting war-birds on the Western Front are once again roaring into action. The three Spads flying in a V formation so precise that they seemed as one. On their trim khaki fuselages, were three identical insignias—each a huge, black-painted picture of a grim-looking mosquito. In the cockpits sat the reckless, inseparable trio known as the “Three Mosquitoes.” Captain Kirby, their impetuous young leader, always flying point. On his right, “Shorty” Carn, the mild-eyed, corpulent little Mosquito, who loved his sleep. And on Kirby’s left, completing the V, the eldest and wisest of the trio—long-faced and taciturn Travis.

Were back with the second of three Three Mosquitoes stories we’re presenting this month. This week Kirby is tasked with flying a spy over the lines who as is usually the case, actually a german spy masquerading as a G-2 agent.

There was something queer about that Intelligence man.
