Mary talked to Mr. Wilson too, but it was no good. She came out looking tired and very sad.
For many months she argued with David Wilson about the danger of the waste products, but he would not listen to her. And so, eighteen months after John’s report, Mary decided to move to another company. She was pleased, because it was a more important job, but that wasn’t the reason she was going. She knew that the cleaning machines would never be built.
John was sad to see her go. He had enjoyed working with her, and she had come to his house several times over the last year and a half. His children liked her now. They had never been so friendly with any woman, since their mother had died.
On her last day, Mary and John had lunch in the factory restaurant together.
