Will O' The Wisp by Pierre Drieu la Rochelle

A disillusioned former soldier drifts through Paris, haunted by addiction and a pervasive sense of emptiness, as he seeks brief comforts in friendships, past loves and ephemeral pleasures; unable to reconcile his longing for authenticity with the banality and moral decay he sees around him, his failed attempts to reconnect and find meaning drive him toward a final, deliberate escape from life.
