For a moment the elder man's eyes blazed, and I thought he was going to strike the youngster. Then, with an effort, he controlled himself, and his voice was ominously quiet as he spoke again.
"You lie, John Trelawnay." His brooding eyes never left the other's face. "It was no storm that drove you here to-day; no thunder that made you call my wife your darling. You came because you knew I was away; because you thought—you and your mistress—that I should not return till to-morrow."
For a while he was silent, while the girl still crouched against the wall staring at him fearfully, and the youngster, realizing the hopelessness of further denial, faced him with folded arms. In silence I watched them from the shadow beyond the fireplace, wondering what I ought to do. There is no place for any outsider in such a situation, much less a complete stranger; and had I consulted my own inclinations I would have left the house there and then and chanced the storm still raging outside. I got as far as putting on my coat again, and making a movement towards the door, when the girl looked at me with such an agony of entreaty in her eyes that I paused. Perhaps it was better that I should stop; perhaps if things got to a head, and the men started fighting, I might be of some use.
And at that moment Rupert Carlingham threw back his head and laughed. It echoed and re-echoed through the room, peal after peal of maniacal laughter, while the girl covered her face with her hands and shrank away, and the youngster, for all his pluck, retreated a few steps. The man was mad, there was no doubt about it: and the laughter of a madman is perhaps the most awful thing a human being may hear.
Quickly I stepped forward; it seemed to me that if I was to do anything at all the time had now come.
"I think, Mr. Carlingham," I said, firmly, "that a little quiet discussion would be of advantage to everyone."
He ceased laughing, and stared at me in silence. Then his eyes left my face and fixed themselves again on the youngster. It was useless; he was blind to everything except his own insensate rage. And, before I could realize his intention, he sprang.
"You'd like me to divorce her, wouldn't you?" he snarled, as his hand sought John Trelawnay's throat. "So that you could marry her.... But I'm not going to—no. I know a better thing than divorce."
The words were choked on his lips by the youngster's fist, which crashed again and again into his face; but the man seemed insensible to pain. They swayed backwards and forwards, while the lightning, growing fainter and fainter in the distance, quivered through the room from time to time, and the two candles supplied the rest of the illumination. Never for an instant did the madman relax his grip on the youngster's throat: never for an instant did the boy cease his sledge-hammer blows on the other's face. But he was tiring, it was obvious; no normal flesh and blood could stand the frenzied strength against him. And, suddenly, it struck me that murder was being done, in front of my eyes.
With a shout I started forward—somehow they must be separated. And then I stopped motionless again: the girl had slipped past me with her face set and hard. With a strength for which I would not have given her credit she seized both her husband's legs about the knees, and lifted his feet off the ground, so that his only support was the grip of his left hand on the youngster's throat, and the girl's arms about his knees. He threw her backwards and forwards as if she had been a child, but still she clung on, and then, in an instant, it was all over. His free right hand had been forgotten....
