Fighting Leathernecks #4

Duke and Quig are assigned to guard Jan Ravic, an escaped Czech official, during a dangerous mission to Vienna—but their attention keeps getting divided by a beautiful woman they meet at the Pentagon, only to discover she's actually a Soviet secret police operative working to capture their charge. When Ravic is kidnapped by Communist forces led by the notorious interrogator Sergei Orloff, the two Marines must fight their way through a deadly trap to rescue him and make their escape back across the Iron Curtain.

On leave in New York, PFC Marmaduke "Duke" Beals and PFC Patrick Michael Quigley are conscripted by the MPs into an unexpected assignment: guarding the prima donna Luba Valinkov at the Metropolitan Opera, where she plans to expose a top Communist agent after her performance. What the two leathernecks don't realize is that enemy operatives have already infiltrated the opera house, dressed as extras and ready to silence her before she can reveal what she knows. With the curtain rising and danger closing in from all sides, Duke and Quig find themselves in the middle of a real-life drama playing out behind the theatrical one.
