“Cyclone Bill” Garrity is back in the thick of things with his Mad Marines in five more weird World War One adventures, where those crazy Germans have devised even more wacky ways to win the war: fooling a British scientist into giving up the secret of a super-explosive he invented by convincing him it’s still 1915 and Germany is England’s ally in a war against France; raining corrosive liquid fire down from the skies, killing everything beneath its deadly downpour; and unleashing a silvery raybeam that can shred anything in it’s brilliant path. And, as if that’s not enough trouble for the Devildog Squadron, there’s the fact that their latest replacement is a dead ringer for the Kaiser’s own brother! Donald E. Keyhoe’s imagination races like a meteor from the Tower of London to a Tarmac of Graves in these brawling adventures blasting out of the pages of Sky Birds: Hangers From Hell (8/34), The Spandau Cyclone (10/34), Devildog Dynamite (11/34), Devil’s Double (12/34), and The Mystery Meteor (1/35).
