The Allies' Manhattan Project (which of course was aimed at developing an atomic weapon before the Germans could do the same) is endangered when a Gestapo agent finds out about the project. He also finds out about Hogan's underground activities, forcing Hogan to consider scuttling his operation. But before he does so, Hogan attempts to trick the Gestapo man into revealing how much he knows about the atom bomb plans. The role of Gestapo operative Herman Freitag is played by Alan Oppenheimer -- an ironic bit of casting, in light of the fact that one of the prime movers of the Manhattan Project was J. Robert Oppenheimer. Written by Phil Sharp, "Two Nazis for the Price of One" originally aired on December 30, 1967. ~ Hal Erickson, Rovi
