"What wild words are these?"
"The words may be wild, but they are true ones. Since these hideous butcheries have been taking place in the surrounding slums and alleys a Vigilance Committee has been formed, with a view of assisting the police. I am a member. This morning I was out on my appointed beat. I saw someone coming down Rainbow Court. I drew back into the shadow, and I stood and I watched. It was you. You had on a rough black overcoat and a cloth cap, and though you were laughing to yourself you seemed desirous of avoiding observation. I wondered what you were doing there at that hour in such a guise. I hesitated a moment whether to follow you. Then I plunged into the court. Just where I had seen you standing I found a woman lying on the ground, dead--murdered--disembowelled; unmistakeably the handiwork of Tom the Tiger. I was so amazed, so horrified, so actually frightened, that for the life of me I could not think what I ought to do. I've been walking about London all night trying to make up my mind. And now I have come to ask you if there is in you sufficient of the man to give you courage to go at once and yield yourself to the police; if there isn't, I shall drag you."
"It's a lie!"
"What is a lie?"
"All that you have said is a lie. You always were a liar, Philip Avalon."
The nephew stared at his uncle. It seemed that he found it hard to believe that a man could be so shapen in iniquity.
"You can still speak to me like that, knowing that I know you. You certainly are, to me, a revelation of infinite possibilities in human nature. But I am not here to palter. Do you intend to surrender yourself, or am I to drag you to the police, or am I to call in the assistance of the people in the street? I give you a minute in which to decide."
The young man took out his watch. Layman and cleric eyed each other. As they did so the Rev. Simon's countenance was transfigured in a fashion which startled his nephew not a little. Before Philip Avalon had guessed his intention, the Incumbent of St Ursula's, hurrying past him, had locked the study door and pocketed the key. As he did so he broke into chuckling laughter. As his nephew surveyed him a glimmer of new light began to find its way into his brain.
"Man! what is the matter with you? What have you done?"
The Rev. Simon continued chuckling. Indeed, it seemed as if he would never stop. And there was something so unpleasant about his laughter that, considerably to his own surprise, Philip Avalon found himself giving way to shudder after shudder.
