Je ne sais pas si c'est une assez bonne histoire mais voilà ce que j'ai écrit:

...she felt ill-at-ease and raised her eyes and caught the eyes of a man dressed in all black who seemed to be reading a newspaper article. He looked quite young, with jet black hair, high cheekbones and a sharp jawline. At first she didn't think much of it, so she just pulled out the thriller book that she has been reading, although, when the staring continued she got a lot more uncomfortable. Thus she thought the best way to get out of that situation was to go to the restroom. Getting up from her seat, she watched as the man started shifting in his, as if getting ready to stand up. All the training that she had received in her teenage years suddenly kicked in. Maintaining her smile and relaxed posture, Janet continued her way to the restroom knowing that the man was still watching her from afar, probably trying not to seem too suspicious but she had already caught him in his act. After nearly five minutes of hiding in the bathroom, she was startled by a knock as she got ready for the fight that was undoubtedly to come. She calmly opened the door and saw the man with his gun raised ready to fire. Thanks to her quick reflexes, Janet quickly disarmed the man and shot him right in the middle of his forhead. She didn't really have trouble doing so as she had maintained her physical condition and he wasn't that expertly trained like her. Nobody heard the gunshot thanks to the silencer attached to the gun, and nobody saw what had just occured , so she took that opportunity and dragged the body into the restroom and cleaned the blood splattered on the floor with a mop she had found. Janet knew exactly what she had to do to get to the bottom of this unexpected attack. She started patting the dead body, taking out another gun from the holster attached to his side hidden behing the long black coat, his wallet, a few receipts and his identification card. None of that was useful for her, so she started undressing the dead man. When he was left with only his underwear, a small black tattoo marked on his chest, and suddenly she didn't know how to breathe anymore. Janet knew that this day would come but it still caught her off guard. As she got up from the floor, a thought crossed  her mind, ''the letter''. She then understood what Julian meant in that letter that she couldn't stop reading and knew that her past was catching up to her. Janet took out her phone from her pocket and called the one person she could really trust. As soo as they picked up, she said ''They're here. You know what to do. Take care of it.''. The only reply that came back throught the line was ''I will''.

Je ne sais pas si c'était ce que vous étiez censé écrire, mais le voici quand même. J'espère que je pourrais aider.
