The encounter with Anna who is stealing openly a collection of poems by Bertolt Brecht in the shop where he works as a bookseller, hits Paul like a flash of lightning. After a delay he runs after her only to lose sight of Anna in the underground station. But a few days later he meets her again “by accident”, and she is starting to stage a play of commitment and withdrawal in which she implicates Paul up to the point of self-abandonment by blind love for her. It is nearly too late when he realises how mentally disordered Anna is, and that she cannot be redeemed through his love. Afterwards there is only the way out for him in the attempt to comprehend these facts in order to save himself.
