"Oh, yes," said Mr. Barnes, determined now to make Mr. Burrows a little uncomfortable. "I have no doubt he intends to skip out, but, of course, he cannot get away. You have him shadowed?"

"Why, no, I have not," said Mr. Burrows, dejectedly. "You see, I did not connect him in my mind with——"

"Perhaps he is not connected with the case in your mind, Burrows, but he is connected with it in fact. He is unquestionably the key to the situation at present. With him in our hands we could decide whether it was he or Randal who pawned those rings. Without him we can prove nothing. In short, until you get at him the case is at a standstill."

"You are right, Mr. Barnes," said Mr. Burrows, manfully admitting his error. "I have been an ass. I was so sure about Randal that I did not use proper precautions, and Morgan has slipped through my fingers. But I'll find his trail, and I'll track him. I'll follow him to the opposite ocean if necessary, but I'll bring him back."

"That is the right spirit, Tom. Find him and bring him back if you can. If you cannot, then get the truth out of him. Let me say one thing more. For the present at least, work upon the supposition that it was he who pawned those rings. In that case he has at least two hundred dollars for travelling expenses."

"You are right. I'll begin at once without losing another minute."

"Where will you start?"

"I'll start where he started—at his own house. He's left there by now, of course, but I'll have a look at the place and talk a bit with the neighbors. When you hear from me again, I'll have Morgan."

Mr. Barnes returned to his home that night feeling well satisfied with his day's work. With little real knowledge he had started out in the morning, and within ten hours he had dipped deeply into the heart of the mystery. Yet he felt somewhat like a man who has succeeded in working his way into the thickest part of a forest, with no certainty as to where he might emerge again, or how. Moreover, though he had seemingly accomplished so much during the first day, he seemed destined to make little headway for many days thereafter. On the second day of his investigation he ascertained one fact which was more misleading than helpful. It will be recalled that Mark Quadrant had told him that his brother had a scar on the sole of his foot made by cutting himself whilst in swimming. Mr. Barnes went to the Morgue early, and examined both feet most carefully. There was no such scar, nor was it possible that there ever could have been. The feet were absolutely unmarred. Could it be possible that, in spite of the apparently convincing proof that this body had been correctly identified, nevertheless a mistake had been made?
