Jekyll's involuntary transformation in Regent's Park
Jekyll's involuntary transformation in Regent's Park is the catastrophic turning point of the novella, the moment when the carefully maintained balance between his two identities collapses without warning and he finds himself permanently trapped in the body of Edward Hyde, a known murderer, with no drug at hand to reverse the change.
The Setting and the False Security
The event occurs on a fine, clear January day, wet underfoot where the frost had melted, but cloudless overhead. Regent's Park was full of winter chirrupings and sweet with spring odours. Jekyll sat in the sun on a bench, the animal within him licking the chops of memory, the spiritual side a little drowsed, promising subsequent penitence but not yet moved to begin. After all, he reflected, he was like his neighbours; and then he smiled, comparing himself with other men, comparing his active good-will with the lazy cruelty of their neglect. This moment of vainglorious self-satisfaction, a brief condescension to his evil, was the precise instant at which the balance of his soul finally destroyed itself.
The Sudden Onset of the Transformation
At the very moment of that vainglorious thought, a qualm came over him, a horrid nausea and the most deadly shuddering. These passed away, and left him faint; and then as in its turn faintness subsided, he began to be aware of a change in the temper of his thoughts, a greater boldness, a contempt of danger, a solution of the bonds of obligation. He looked down; his clothes hung formlessly on his shrunken limbs; the hand that lay on his knee was corded and hairy. He was once more Edward Hyde. A moment before he had been safe of all men's respect, wealthy, beloved—the cloth laying for him in the dining-room at home; and now he was the common quarry of mankind, hunted, houseless, a known murderer, thrall to the gallows.
The Immediate Consequences
This involuntary transformation was fundamentally different from all previous ones. Earlier, Jekyll had chosen to drink the potion and become Hyde; now the change seized him without his consent, in broad daylight, in a public park, with no drugs anywhere near. His reason wavered but did not fail him utterly. He observed that in his second character, his faculties seemed sharpened to a point and his spirits more tensely elastic; thus it came about that, where Jekyll perhaps might have succumbed, Hyde rose to the importance of the moment. His drugs were in one of the presses of his cabinet; the problem of how to reach them—with the laboratory door closed and his own servants ready to consign him to the gallows—set him to devise the desperate plan that led to his letter to Lanyon and the final revelation of the truth.
