Rayburn did his duty, and protected a helpless woman? There is my plan, sir. Is it worth trying?"

He answered, sharply enough: "I don't like it."

The housekeeper opened the door again, and wished him good-by.

If Mr. Rayburn had felt no more than an ordinary interest in Mrs. Zant, he would have let the woman go. As it was, he stopped her; and, after some further protest (which proved to be useless), he ended in giving way.

"You promise to follow my directions?" she stipulated.

He gave the promise. She smiled, nodded, and left him. True to his instructions, Mr. Rayburn reckoned five minutes by his watch, before he followed her.

XII.

THE housekeeper was waiting for him, with the street-door ajar.

"They are both in the drawing-room," she whispered, leading the way upstairs. "Step softly, and take him by surprise."

A table of oblong shape stood midway between the drawing-room walls. At the end of it which was nearest to the window, Mrs. Zant was pacing to and fro across the breadth of the room. At the opposite end of the table, John Zant was seated. Taken completely by surprise, he showed himself in his true character. He started to his feet, and protested with an oath against the intrusion which had been committed on him.

Heedless of his action and his language, Mr. Rayburn could look at nothing, could think of nothing, but Mrs. Zant. She was still walking slowly to and fro, unconscious of the words of sympathy which he addressed to her, insensible even as it seemed to the presence of other persons in the room.

John Zant's voice broke the silence. His temper was under control again: he had his reasons for still remaining on friendly terms with Mr. Rayburn.

"I am sorry I forgot myself just now," he said.

Mr. Rayburn's interest was concentrated on Mrs. Zant; he took no notice of the apology.

"When did this happen?" he asked.

"About a quarter of an hour ago. I was fortunately at home. Without speaking to me, without noticing me, she walked upstairs like a person in a dream."

Mr. Rayburn suddenly pointed to Mrs. Zant.

"Look at her!" he said. "There's a change!"

All restlessness in her movements had come to an end. She was standing at the further end of the table, which was nearest to the window, in the full flow of sunlight pouring at that moment over her face. Her eyes looked out straight before her--void of all expression. Her lips were a little parted: her head drooped slightly toward her shoulder, in an attitude which suggested listening for something or waiting for something. In the warm brilliant light, she stood before the two men, a living creature self-isolated in a stillness like the stillness of death.

John Zant was ready with the expression of his opinion.

"A nervous seizure," he said. "Something resembling catalepsy, as you see."

"Have you sent for a doctor?"

"A doctor is not wanted."

"I beg your pardon.
