Then next moment came a crash of thunder; but before the thunder a white light had filled the whole room for a single split second.

Fisher had seen two things in front of him. One was the black-and-white pattern of the iron grating against the sky; the other was the face in the corner. It was the face of his brother.

Nothing came from Horne Fisher’s lips except a Christian name, which was followed by a silence more dreadful than the dark. At last the other figure stirred and sprang up, and the voice of Harry Fisher was heard for the first time in that horrible room.

“You’ve seen me, I suppose,” he said, “and we may as well have a light now. You could have turned it on at any time, if you’d found the switch.”

He pressed a button in the wall and all the details of that room sprang into something stronger than daylight. Indeed, the details were so unexpected that for a moment they turned the captive’s rocking mind from the last personal revelation. The room, so far from being a dungeon cell, was more like a drawing-room, even a lady’s drawing-room, except for some boxes of cigars and bottles of wine that were stacked with books and magazines on a side table. A second glance showed him that the more masculine fittings were quite recent, and that the more feminine background was quite old. His eye caught a strip of faded tapestry, which startled him into speech, to the momentary oblivion of bigger matters.

“This place was furnished from the great house,” he said.

“Yes,” replied the other, “and I think you know why.”

“I think I do,” said Horne Fisher, “and before I go on to more extraordinary things I will, say what I think. Squire Hawker played both the bigamist and the bandit. His first wife was not dead when he married the Jewess; she was imprisoned on this island. She bore him a child here, who now haunts his birthplace under the name of Long Adam. A bankruptcy company promoter named Werner discovered the secret and blackmailed the squire into surrendering the estate. That’s all quite clear and very easy. And now let me go on to something more difficult. And that is for you to explain what the devil you are doing kidnaping your born brother.”

After a pause Henry Fisher answered:

“I suppose you didn’t expect to see me,” he said. “But, after all, what could you expect?”’
