astily replaced the cloth, shuddering convulsively as he did so.
Then he returned to his room.

He sat down upon the edge of his cot, and held his head in his hands.
When he looked up his violent mood had passed away. He seemed to wish to
talk.

"It was a hideous dream," he said.

"Murder?" asked Nick.

"There was murder in it," replied the doctor. "I thought that I had
killed--that I had killed a man."

"Patrick Deever?"

"How the devil did you know that?" cried the doctor, springing to his
feet.

"Well, sir, the man has disappeared, and--"

"And somebody has been filling your head with foolish stories. Who was
it?"

"Mr. Deever was asking some questions about his brother."

"And you told him everything you knew, and a good deal more, I suppose?"

"I didn't tell him anything."

"It's lucky for you that you didn't. Now, look here, Cleary, you know
where your interest lies. Don't you lose a good job by talking too
much."

"No, sir; I won't. But there's something in dreams, and--"

"There was agony in this one. I thought that I had killed Deever, and
was obliged to hide his body. I felt that the police were close upon me.

"No, sir; certainly not."

"But suppose I did? What then?"

"Well, sir; it's a terrible thing. I--"

"Would you betray me?"

"I would not say a word unless I was sure that you were guilty."

"Even then, why should you speak?"

"There's a conscience, and--"

"Nonsense! What business is it of yours? Now look here; you think a good
deal more about money than you do about your conscience. I've got money,
and I'm willing to pay well to keep out of trouble."

"But I don't want to get into any."

"You won't. All you've got to do is to keep still."

"Keep still about what, sir?"

"This sleep-walking to-night."

"I won't say a word, unless--"

Nick hesitated. He wished to give the doctor the impression that his
innocence was by no means clear, and that the idea of shield
