"

"That's what I thought, but Maria seemed crazed like."

"I tell you he did it! Are you going to let him go, the red-handed
murderer?"

"Loose the cord, and I will question the boy," said Dr. Park, with an
air of authority.

Carl breathed a sigh of relief, when, freed from his bonds, he stood
upright.

"I'll tell you all I know," he said, "but it won't throw any light upon
the death."

Dr. Park listened attentively, and asked one or two questions.

"Did you hear any noise when you were sitting at the table?" he
inquired.

"No, sir."

"Was the door closed?"

"Yes, sir."

"That of itself would probably prevent your hearing anything. Mrs.
Brown, at what hour did you leave the house?"

"At ten minutes of twelve."

"It is now five minutes of one. The deed must have been committed just
after you left the house. Had you noticed anything out of the way in

"No, sir, not much. He was always a silent man."

"Had anything happened to disturb him?"

store you will find me cold and dead. The little that I leave behind I
give to you. If my first wife should come here, as she threatens, you
can tell her so. Good-by.

"William."

The reading of this letter made a sensation. Mrs. Brown went into
hysterics, and there was a scene of confusion.

"Do you think I can go?" Carl asked Dr. Park.

"Yes. There is nothing to connect you with the sad event."

Carl gladly left the cottage, and it was only when he was a mile on his
way that he remembered that he had not paid for his dinner, after all.

CHAPTER IX.

A PLAUSIBLE STRANGER.

Three days later found Carl still on his travels. It was his custom
to obtain his meals at a cheap hotel, or, if none were met with, at a
farmhouse, and to secure lodgings where he could, and on as favorable
terms as possible. He realized the need of economy,
