Helmut Schultz— a major in counterintelligence, was recalled from the front to Berlin to find a "mole" — a traitor in the highest government circles of Germany.

Helmut does not obey any of the army Generals, his activities are secret, and no one can interfere with his investigation.

For a couple of days now, everyone sitting in the government building has been under suspicion by Helmut Schultz.

You're a Russian intelligence officer, a radio operator.

You have been working as a secretary for General Olaf Merz for more than three years. Merz treats you positively, like the daughter he never had. Your espionage work is impeccable. You transmit a lot of important information to your homeland.

One night you were returning from the location of the walkie-talkie, just twenty minutes ago you transmitted important information to your homeland.

You were passing through a dark alley at the moment when you heard the click of a lighter.
