"You told me the baron betrayed no sorrow at the disappearance of your daughter."
"I so interpreted his tone and manner. Now tell me, sir, what you have learned."
"I have not learned anything positively, but let me ask you, is there any one else who would have a motive in abducting your daughter?"
"I know of no one else."
The detective had learned facts which threw a new light on the affair, and he went to meet August Wagner under different impressions than had governed him when he first started upon the young man's trail.
Jack met young Wagner and went to the opera with him, and during the course of the evening he saw the young man acknowledge a recognition from a party in one of the boxes. The detective did not immediately inquire who the parties were, but he observed that Wagner sought to avoid any further recognition, and just before the close of the last act he said:
"I will go out if you will excuse me."
"I have had enough of it; I will go with you," said Jack, adding: "We will go and have some supper."
The young men left the theater, and once outside, young Wagner said:
"I cannot go and have supper with you."
