Volume V of Les Misérables brings the novel to a powerful and heartbreaking conclusion, weaving together themes of revolution, sacrifice, and redemption. As the June Rebellion collapses, Jean Valjean rescues the wounded Marius and escapes through the Parisian sewers, a harrowing journey that symbolizes his final trial. Meanwhile, Javert, faced with the unbearable conflict between duty and mercy, ultimately takes his own life, unable to reconcile Valjean's goodness with his rigid sense of justice.

With Marius recovered and reunited with Cosette, Valjean begins to withdraw from their lives, believing his past as a convict will tarnish their future. Marius, initially unaware of Valjean's sacrifices, grows distant until he discovers the truth-that Valjean saved him from certain death. Overcome with guilt, he and Cosette rush to Valjean's side as the old man, now frail and nearing the end of his life, quietly awaits his fate.

In a deeply moving final scene, Valjean finds peace in Cosette's presence, confessing his past and offering his last words of wisdom before passing away. Hugo closes the novel with a meditation on love, loss, and the passage of time, as Valjean's unmarked grave fades into obscurity. The volume serves as a poignant reflection on justice, grace, and the enduring power of selfless love.
