In a small room on the 6th floor, in the passage de l’Industrie, 63-year-old Chevrel, a coffee house clerk, lived with his 30-year-old wife. The woman, whose maiden name was Marie Guez, had continued to live with Chevrel after they met one night. Later Chevrel married the girl because she did so much housework, but no sooner had this marriage been consummated than Marie Guez changed her habits, slept late, drank, and led a bad life. Chevrel wanted to throw her at the door, but the woman managed to persuade him. Chevrel tried his best and no longer cared much about the woman, but when he returned home one night to find his cousin with his wife, it became too much for him. He threw the nephew at the door and wanted to do the same with the woman, but the latter managed to soften his heart through tears.
The woman and the cousin René Chevrel, 23 years old, continued to meet in secret. The young man had been pressing for some time for Marie Guez to come live with him in Levallois, but she always refused. Yesterday the couple had another meeting in the passage de l’Industrie. The woman sat on the bed and the young man, holding a small revolver, repeated his question. “If I leave here, it might not be with you,” Marie Guez replied. René Chevrel then fired. Marie Guez was hit in the right side and the bullet pierced the liver. When the young man realized what had happened, he rushed downstairs and went to the police station. Despite his remorse, he was imprisoned.
