Agent Lark

In Bernauer Straße the border ran along the house fronts: the pavement was in the West, the buildings in the East. In the autumn of 1964 a group of students dig their way forward twelve metres under the street, from a disused bakery in the West to a back yard in the East. Lark is the cover name of their courier. She has a West German passport and can cross the border and come back the same day. Her job is to tell those who are to escape: which doorway, which night – and which word to whisper in the dark. You walk along the Wall today with her diary. At every stop you have to find something that stands there now. Each stop gives a letter, and in the end the password. Lark and the diary are made up. The tunnels, the numbers and the password are real.
