“It was night, monsieur,” he hesitatingly said, “and, having a violent headache, I took a walk along the quay thinking there was no risk in my entering a cafe; there I picked up a paper, and read the dreadful announcement.”

“The best thing we can do is to try and repair the harm you have done. When and where did you post this idiotic letter?”
