In Chapter 17 from the complete adventures of Indiana Jones, Indy discovers that the face of evil is not always human.

Istanbul, September 1918. Posing as neutral Swedish journalist 'Nils Anderson', Indiana Jones is trying to convince Turkish general Mustafa Kemal to form a separate peace with the allies instead of the Germans. His mission becomes jeopardized when he learns there is a traitor, codenamed 'The Wolf' in his spy network. Afterwards, as part of a small team of special agents, Indy is sent to Transylvania to find out why the mysterious General Targo has raided a German P.O.W. camp. They soon found out the General had taken up impaling his enemies, just like Vlad Tepes used to in the 15th century.—Il Tesoro
