recognizable face, but Hesselman attempts to have the image enhanced by computer, a process that may take days. Army CID officers, commanded by Major Donovan, scour Atwell's apartment for evidence. Meanwhile, as his initial shock begins to wear away, Farrell realizes that Brice is the real murderer and that Pritchard is helping him cover up the crime. He also realizes that the physical evidence will make him the prime suspect. Farrell decides to play along with the bogus investigation until he can develop evidence linking Brice to Atwell, and defend himself against being charged with both murder and espionage. Farrell learns that one piece of evidence is a Moroccan jewel box, a gift to Atwell from Brice. As any foreign gift must be registered with the State Department, Farrell gets Hesselman to "raid" State's computerized registry of such items, which should link the box to Brice.

Farrell manages to get into Brice's office, locks the door, and confronts him with the printout of the gift registry data. Brice improvises a different story to buy Farrell's silence: Pritchard, who is gay, killed Atwell out of jealousy of Brice's relationship with her. The devastated and betrayed Pritchard realizes he's cornered and shoots himself. When the guards finally break into the locked office Brice tells them that Pritchard confessed to being Yuri, concluding the search for the spy. Farrell quietly sends the printout by courier to the Director of the CIA, a political rival of Brice, then leaves the Pentagon as the finished image enhancement of the
