The poisonous old lady

In her neighbour's eyes, Gloria was a friendly old cookie lady, living alone in her little suburban pavilion. All were unaware that she was the infamous author of 30 murders between 1960 and 1990, never caught. Expert in chemistry, her specialty was poisoning.
As she grew older, and after a case where she was neraly captured, Gloria stood up. Yet the urge to murder was still present ...

Then, one day as she was working in her secret laboratory to make a poison that she would disseminate in her neighborhood for her last coup d'éclat, she had an accident. Product spilled over her. She collapsed to the ground with a terrible pain and thought her death had come. But the next day she awoke in great form.

Gloria opened her newspaper as usual. When she discovered the mayor's picture, which she hated for her arrogant smile, she was once again caught up in her desire for murder. She felt a burn over her body and realized with amazement that she was now ... a man in her forties. The mayor's exact reply. At that moment she discovered the side effect of her chemical: Gloria could now alter her appearance at will.

She took a week to test her power, activated by her desire to kill. Then another week to prepare her return of killer, under the guise of a girl with the face of angel. This time, no one would be able to stop him.
