Everyone please remember that PLAGIARISM is unethical and very much frowned upon by all institutions of learning, so please give Victor Hugo, the other writers referenced on my page, and myself credit for referenced material.
Well I will cut to the chase...Quasimodo dies at the end of the story. And NOT among friends, in a warm bed, with the bells tolling for him.
Quasimodo is arrested by Captain Phoebus for trying to abduct Esmeralda. Quasimodo then goes to court before a deaf judge (quite the funny scene) and is sentenced to lashings and the pillory. During this pillory scene Esmeralda brings the hunchback some water. This single act creates the spark in Quasimodo for Esmeralda. Quasimodo repays this debt when he rescues Esmeralda just before her execution on grounds of witchcraft. However, during the rescue, Quasimodo does not swing from a rope, he descends by a rope to the ground. He then runs to Esmeralda, attacks the guards, grabs her, yells "sanctuary", and retreats to the cathedral. After this daring rescue Esmeralda spots Phoebus from atop the cathedral and asks Quasimodo to summon him. While the insensitive gypsy shouts her undying love to the Captain (who is out of earshot), Quasimodo whispers to himself:
Gnashing his teeth, he said in a whisper, "Damnation! So that's how a man should be! He need only be handsome on the outside!" book9 chap4
When Quasimodo reaches the Captain he denies ever knowing her, kicks the hunchback in the chest, and rides off. Quasimodo tells Esmeralda that he could not find him and is scorned for not trying hard enough.
For four years Esmeralda lives a solitary existence in Notre-Dame. However, the government has not forgot about her and the Parliament sets forth a decree for her execution in three days. They plan on removing her from the cathedral by force if necessary (this was not uncommon either back then). So Claude and Pierre devise a plan of rescuing her by having the Truands (riffraff) attack the cathedral and take her. Of course Quasimodo knows nothing of this plan and attacks the Truands when they storm Notre-Dame. First he throws a wooden beam on the Truands ramming the door, then stones, and finally molten lead.
They who had cried out, they who were still alive, looked, and saw two jets of molten lead falling from the top of the edifice into the thickest of the crowd. The waves of human sea parted under the boiling metal, which, at the two spots where it fell, made two black and reeking hollows in the crowd, like the effect of hot water thrown upon snow. There were dying wretches burned in half to cinder and moaning in agony. Around the two principal jets drops of that horrible rain fell scatteringly on the assailants, penetrating their skulls like red-hot gimlets. book10 chap4
Later, during the siege of Notre-Dame, Quasimodo can be found killing Jehan by knocking his brains out of his skull then throwing the corpse off the cathedral. After the siege ends, he races down to Esmeralda's cell to show her that he saved her life twice now, but she is gone. Claude and Pierre stole her out the cathedral's back door during the fighting. Quasimodo does not go out looking for the gypsy and stays in the cathedral.
When Claude returns to the cathedral, after turning the gypsy over to the authorities, he heads up for the roof to watch the execution. Here, Quasimodo and Claude watch the execution of Esmeralda at the gallows. However, Claude appears to be enjoying this spectacle a little too much and Quasimodo puts an end to that.
At that most dreadful moment, a demoniacal laugh, a laugh such as can come only from one which is not human, burst from the livid face of the priest. Quasimodo didn't hear the laugh, but saw it. The bellringer took a few steps back from the archdeacon, and then, rushing at him furiously, with his two huge hands, he struck the priest's back and pushed Dom Claude into the abyss over which he had been leaning. book11 chap2
After murdering Claude, Quasimodo disappears from society. He is found years later in the charnelhouse beneath the Montfaucon (a famous gibbet).
As for the mysterious disappearance of Quasimodo, this is all we could discover.
About a year and a half or two years after the events which conclude this story, when a search was made in the vault of Montfaucon for the body of Olivier le Daim, who had been hanged two days before, and to whom Charles VIII granted the favor of being interred in the church of Saint Laurent with better company, there was found among all those hideous carcasses two skeletons, the one clasped in the arms of the other. One of these two skeletons, that of a woman, had still about it some tattered clothes, apparently of a stuff that had once been white. About its neck was a string of beads of adrezarach seeds, together with a small silken bag, ornamented with green glass, which was open and empty. These objects had been of so little value that the hangman, no doubt, had not cared to take them. The other skeleton, which held this one close in its arms, was that of a man. It was noticed that its spine was crooked, the head compressed between the shoulder blades, and that one leg was shorter than the other. Also, there was no break in the vertebra in the neck, whence it was evident that it had not been hanged. the man to whom it had belonged had therefore come there of himself and died there. When they tried to detach this skeleton from the one it embraced, it crumbled to dust. book11 chap4
