The Purple Invasion story #13 of 13. What has become known as the “War in Peace of the Pulps”, the legendary Purple Invasion lasted an amazing 13 installments.

At last, victory was within the grasp of Operator 5 and his little band of American fighters. Then came the Emperor's final trump card — a foul, slaying miasma which loosed itself over the land, bringing a torturing, horrible death — which all men knew and feared as Europe's medieval Black Plague!
