Wein, Novick and McLaughlin kick off a two-part Two-Face tale in Batman 313 (July 1979).
Two-Face has stolen the codes for a binary missile defense system, but rather than jut sell it back to the military, as he had told his gang he would, Two-Face is also offering the information to the Russians. As he says, a classic double cross.
Bruce Wayne is out on a date with Selina Kyle when the Bat-signal alerts him. Thing are starting to get serious between the two of them.
Batman discovers that he is not the only one pursuing Two-Face, as he runs into King Faraday, a government agent, last seen in Showcase 100 the previous year.
We also get more about Lucius Fox’s home life. While his daughter Tiffany is a good girl, volunteering with ghetto kids, his son Timothy has a strained relationship with his dad.
At the climax of the issue, Faraday and Batman catch up to Two-Face. Faraday is about to shoot him, but Batman pulls the gun away. He insists that Two-Face is ill, and should not be killed. Faraday is furious, and warns Batman not to interfere with him again.
The story conclude in the next issue.
