Field-Marshal Eugen von Schwartau, the Caucasian Fox, led his Nazi stormtroopers to the very gates of Moscow, striking terror into the heartland of Russia. Now, with the fortunes of war temporarily going against the Germans, von Schwartau had his troops poised for a crippling attack on the Russian oilfields. The Allies needed commandos that could be as cunning and as deadly as the Caucasian Fox himself. The Dirty Devils, led by the wild, one-eyed Mark Crooke, were the only men who could meet terror with terror, and their orders included the death of the Caucasian Fox himself.
