The Tunnel

In William H. Gass's second novel, a history professor named William Kohler writes a scholarly book called 'Guilt and Innocence in Hitler's Germany,' and intersperses a personal memoir in the pages of the manuscript. In the meantime, he is digging a secret tunnel from his basement. The primary thrust of the novel appears to be one which Gass has written on many times before; that there is no true, concrete reality, only our perceptions and interpretations of the events which occur around us.
