Arkady reluctantly pays a visit to his father, retired Red Army General Renko, a.k.a. "Stalin's Favorite General", a.k.a. "The Butcher of Ukraine". The elder Renko remembers that Osborne was an O.S.S. officer attached to the Red Army during the Nazi invasion, tasked with interrogating three captured S.S. officers. Thanks to his charm and fluent German, Osborne got the information he needed from the officers over a friendly picnic in the countryside, then shot all three of them dead - almost exactly the manner in which the three bodies in Gorky Park were killed.
