“The evidence shall be presently indicated,” replied the lawyer.

The judge passed on the objection at once.

“The Colonel promises to point out the evidence later. He may go on; the witness has been introduced as an expert.”

The lawyer again faced the man in the chair. He repeated his question.

The witness seemed doubtful.

“I don’t know,” he said.

“You don’t know! Reflect, Mr. Barkman. Would it not mean that the person or persons who accomplished this criminal act felt that they were so well known to Hiram Halloway that no ordinary disguise could conceal their identity?”

The witness did not immediately reply, and the lawyer went on:

“And is not this the reason why Hiram Halloway was killed?”

“Why he was killed!” repeated the man in the chair.
