Critics typically regard Abe Kobo (1924-93) as writing against realism, due to his avant-garde aesthetics that challenged the Naturalist realism dominating the literary mainstream and the Socialist realism of the orthodox Left in postwar Japan.

Undergirding his theory and practice of realism was a critique of conventional documentary and of the classic detective story. The texts examined here expose the degree to which the documentarian and the detective are active fabricators of meaning rather than neutral observers of fact.

Truth from a Lie explores the ways in which Abe put documentary and the de
