Hyde's suicide
Hyde's suicide is the culminating event of Robert Louis Stevenson's Strange Case of Dr Jekyll and Mr Hyde, the moment when the monstrous alter ego, unable to sustain his separate existence and facing capture, destroys himself with a poisoned phial. The act simultaneously extinguishes the life of Henry Jekyll, whose identity Hyde had usurped, and provides the physical evidence that finally confirms the horrifying truth of their shared identity to the surviving characters. It is the violent, necessary end to a duality that had become unsustainable.
Discovery of the Body
After breaking down the door of the cabinet with an axe, Mr. Utterson and Poole find the room in orderly quiet, with a fire glowing and tea things set out. In the middle of the floor lies the body of a man, sorely contorted and still twitching. They turn it over and behold the face of Edward Hyde. He is dressed in clothes far too large for him—clothes of the doctor's bigness. The cords of his face still move with a semblance of life, but life is quite gone. A crushed phial lies in his hand, and the strong smell of kernels hangs upon the air, leading Utterson to recognize that he is looking on the body of a self-destroyer. Utterson sternly declares, "We have come too late, whether to save or punish. Hyde is gone to his account; and it only remains for us to find the body of your master." A thorough search of the building—the theatre, the closets, the cellar sealed by cobwebs—reveals no trace of Henry Jekyll, dead or alive.
The Circumstances of the Act
The suicide is the culmination of a week-long crisis. For eight days, the creature in the cabinet—whom Poole identifies as Hyde by his stature and movements—had been desperately ordering various drugs from wholesale chemists, only to reject each sample as impure, crying out for "some of the old." The transformative drug, whose original salt had never been renewed, had lost its efficacy; Jekyll's first supply had been impure, and that unknown impurity alone lent power to the draught. With the last of the old powders, Jekyll writes his confession, knowing that when the throes of change take him, Hyde will tear it in pieces. He foresees his own end: "Will Hyde die upon the scaffold? or will he find courage to release himself at the last moment?" Hyde, facing the certainty of capture and the gallows, chooses the latter, taking the poison that ends both his own life and Jekyll's.
The Evidence Left Behind
In the cabinet, the searchers find a new will, drawn in the same eccentric terms as the original but naming Gabriel John Utterson as heir instead of Edward Hyde. Utterson, amazed, realizes that Hyde had been in possession of the cabinet for days and had not destroyed this document that displaced him. A brief note from Jekyll, dated that very day, instructs Utterson to first read Lanyon's narrative and then turn to Jekyll's own confession. A considerable packet, sealed in several places, is handed over by Poole. The key to the by-street door lies nearby on the flags, broken and rusted, suggesting it had not been used. The cheval-glass, which Utterson notes must have seen strange things, stands turned to show only the firelight and the pale, fearful faces of the living.
Significance
Hyde's suicide is the final, irreversible act that closes the case. It provides the physical proof—the body of Hyde, the crushed phial, the confessional documents—that allows Utterson and the reader to reconstruct the full truth of Jekyll's double life. The event also fulfills the tragic arc of the narrative: the evil that Jekyll unleashed could not be contained, and the only resolution is mutual destruction. Hyde's death is not a redemption but a desperate escape from the scaffold, a final assertion of his own will even as he extinguishes the life he shared with Jekyll. The novel ends not with a moral lesson but with the stark, silent image of a body on the carpet, the mystery laid bare but the horror left to linger.
