The Vienna Pads

At 07:30 this morning, the Vienna station found its one-time pads out of order in the safe. The safe log shows it was opened at 22:08 last night with the station code. By midnight, the opposition had stopped using the radio channel those pads were made to read.

The station is a flat above a piano shop in Neubau. The station code opens both the yard door and the safe. After 21:00 the building was meant to be empty except for the duty officer downstairs.

Five officers know the station code. One of them works for the other side. You have 12 questions across all five. Spend them, then name the mole. You get one accusation.

The suspects are played by Claude, an AI model. Your questions are stored with your game and sent to Anthropic to write the replies, so leave personal details out of them. Privacy
