With Prague’s grand castles and elegant squares overflowing with happy visitors and marquee shopping it is easy to forget that this is also the city of Franz Kafka. Metamorphosis happens here, whether it is a human turning into a bug, or the curved shapes of a nearly empty street altered in the reflection in a traffic mirror. The outer world is unaltered, but inside the metamorphosis the lone pedestrian wanders down a twisted street towards an uncertain end.
