Suddenly he stopped abruptly. Huddled up in the corner of a seat was a man with a cloth cap pulled forward screening his face: at that moment Lord Wolfenden was in a mood to be extravagantly generous to any poor applicant for alms, lavishly sympathetic to any tale of distress. But it was not ordinary curiosity that arrested his progress now. He knew almost at the first glance who it was that sat in this dejected attitude, although the opera hat was replaced by the soft cloth cap, and in other details the man's appearance was altered. It was indeed the Mr. Felix who had supped with him at the "Milan" and subsequently behaved in so astonishing a fashion. He knew that he was recognised, and sat up, looking steadfastly at Wolfenden, although his lips trembled and his eyes gleamed wildly. Across his temples a bright red mark was scored. Lord Wolfenden broke the silence. "You're a nice sort of fellow to ask out to supper! What in the name of all that's wonderful were you trying to do?" "I should have thought it was sufficiently obvious," the man replied bitterly. "I tried to kill him, and I failed. Well, why don't you call the police? I am quite ready. I shall not run again." Wolfenden hesitated, and then sat down by the side of this surprising individual. "The man you went for didn't seem to care, so I don't see why I should. But why do you want to kill him?" "To keep a vow," the other answered; "how and why made I will not tell you." "How did you escape?" Wolfenden asked abruptly. "Probably because I didn't care whether I escaped or not," Felix replied, with a short, bitter laugh. "I stood behind some shrubs just inside the garden, and watched the hunt go by. Then I came out here and sat down." "It all sounds very simple," said Wolfenden, a trifle sarcastically. "May I ask what you are going to do next?" Felix's face so clearly intimated that he might not ask anything of the kind, or that if he did his curiosity would not be satisfied, that Wolfenden felt compelled to make some apology. "Forgive me if I seem inquisitive, but I find the situation a little unusual. You were my guest, you see, and had it not been for my chance invitation you might not have met that man at all. Then again, had it not been for my interference he would have been dead now and you would have been in a fair way to be hanged." Felix evinced no sign of gratitude for Wolfenden's intervention. Instead he said intensely, "Oh, you fool! you fool!" "Well, really," Wolfenden protested, "I don't see why----" But Felix interrupted him.
