“Well—it might be—” said Peter, shyly.

“It ought to be easy,” continued the detective. “Them Reds are all free lovers, you know.”

“Free lovers!” exclaimed Peter. “How do you mean?”

“Didn’t you know about that?” laughed the other.

Peter sat staring at him. All the women that Peter had ever known or heard of took money for their love. They either took it directly, or they took it in the form of automobile rides and flowers and candy and tickets to the whang-doodle things. Could it be that there were women who did not take money in either form, but whose love was entirely free?

The detective assured him that such was the case. “They boast about it,” said he. “They think it’s right.” And to Peter that seemed the most shocking thing he had yet heard about the Reds.

To be sure, when he thought it over, he could see that it had some redeeming points; it was decidedly convenient from the point of view of the man; it was so much money in his pocket. If women chose to be that silly—and Peter found himself suddenly thinking about little Jennie Todd. Yes, she would be that silly, it was plain to see. She gave away everything she had; so of course she would be a “free lover!”

Peter went away from his rendezvous with McGivney, thrilling with a new and wonderful idea. You couldn’t have got him to give up his job now. This sleuthing business was the real thing!

It was late when Peter got home, but the two girls were sitting up for him, and their relief at his safe return was evident. He noticed that Jennie’s face expressed deeper concern than her sister’s, and this gave him a sudden new emotion. Jennie’s breath came and went more swiftly because he had entered the room; and this affected his own breath in the same way. He had a swift impulse towards her, an entirely unselfish desire to reassure her and relieve her anxiety; but with an instinctive understanding of the sex game which he had not before known he possessed, he checked this impulse and turned instead to the older sister, assuring her that nobody had followed him. He told an elaborate story, prepared on the way; he had worked for ten days for a fellow at sawing wood—hard work, you bet, and then the fellow had tried to get out of paying him! Peter had caught him at his home that evening, and had succeeded in getting five dollars out of him, and a promise of a few dollars more every week. That was to cover future visits to McGivney.
