Various short stories (generally not as good as in Metamorphosis) and a short play. Several have legal/bureaucratic themes and others continue his habit of first-person musings, imagining himself as another creature (Report of a Dog
and The Burrow
). The Burrow is a very touching insight into the concept of home as a castle, fear of intrusion and persecution etc - very easy to add a Jewish spin to the interpretation.
