"I am his nephew," David answered. "I am the little boy who played about the park when you were a girl, who picked you up on the ice once when you fell. All that I have I owe to Richard Vont. He sent me to college. He lent me the money upon which I built my fortune, but on the day he lent it to me he made me swear a terrible oath, and to-night he has forced me to keep it by setting foot within your chamber. Now I shall return the way I came, and may God grant that some day you will forgive me."

Almost as he spoke there was a little click behind. He started round and felt along the wall. There was a moment's silence. Then he turned once more towards Letitia, his cheeks whiter than ever, his sunken eyes filled with a new horror. Even the composure which had enabled him to explain his coming with some show of reason, had deserted him. He seemed threatened with a sort of hysteria.

"He followed me! Damn him, he followed me!" he muttered. "I heard footsteps. He has fastened us in!"

He tore desperately at the tapestry, shook the concealed door and rattled it, in vain. Letitia rose slowly to her feet.

"You see what has happened," she said. "Richard Vont was more cunning than you. He was not content that you should make your little speech and creep back amongst the rats. Tell me, what do you propose to do?"

He looked around him helplessly.

"There is the window," he muttered.

She shook her head.

"We are on the second story," she told him, "and there is nothing to break your fall upon the flags below. To be found with a broken neck beneath my window would be almost as bad as anything that could happen."

"I am not afraid to try," he declared.
