 In what amounts to a confession, Clamence tells of his success as a wealthy Parisian defense lawyer who was highly respected by his colleagues; his crisis, and his ultimate "fall" from grace, was meant to invoke, in secular terms, The Fall of Man in the Garden of Eden.
 "The Fall" explores themes of innocence, imprisonment, non-existence, and truth.
