The first half of the work examines the role of secrecy in contemporary political and legal practices-including the question of transparency in democratic processes during the Bush Administration, the principle of public justice in England's response to the war on terror, and the evidentiary law of spousal privilege. The second half of the book explores legal, literary, and filmic representations of secrets in law, focusing on how knowledge about particular cases and crimes is often rendered opaque to those attempting to access and decode the information. Those invested in transparency must ultimately cultivate a capacity to read between the lines, decode the illegible, and acknowledge both the virtues and dangers of the unknowable.
