Feeling that our further stay was an intrusion, Rivers and I took leave, and Wise came along with us. We three went down to my rooms, and continued our confab without the embarrassment of Olive’s presence.

“It’s clearing itself up pretty quickly in some respects,” Wise said as he settled himself with a cigar, and passed the box to Rivers. “I’m not so surprised as some at Gately’s perfidy. It seems the Government has been onto him for some time,—at least, they suspected him, and were secretly investigating his private affairs. That Sadie person——”

“By the way, Wise,” I interrupted him, “you sized her up perfectly! Did you ever hear about that, Rivers? Mr. Wise saw only the girl’s hatpin, and from it he drew an exact portrait of ‘The Link’ herself. How did you do it, Wise? Tell us the details.”

“Like all those deductions it was simpler than it sounded,” the detective said, smiling. “You see, Mr. Rivers, the head of the pin was a big good-looking scarab. I don’t know yet whether it was a real one, but if not it was a first-class imitation. This argued a person of education and taste. The average young woman doesn’t lean toward scarabs. Then, there was a short bit of a human hair caught in the setting. This was black, rather coarse, and strong, denoting a healthy, buxom brunette. Hair is a clear indication of physical appearance, as a rule. That’s how I know you aren’t Amory Manning,” he broke off suddenly and looked at Case Rivers. “I’ve had his description from Miss Raynor and from Brice, here, and they agree that Manning had dark, heavy hair, rather—footballish type. Yours is light, fine, and a little scant. And you have all the characteristics that belong to it. Oh, yes, I admit I’ve been trying to fasten Manning’s identity on you, but without success.”

“Don’t apologize,” laughed Rivers, “I’ve been trying to connect up with the missing Manning myself, but I can’t work it. So, I’m out for the reward for finding that elusive individual. But I fear he’s gone beyond recall.”

“By the way,” Wise put in, “I’ve found out who offers the reward. And, if you please, it’s none other than the United States Government!”

“Why?” Rivers asked, interestedly.

“Well, it seems Manning is,—or was,—a Secret Service man and he was set on the trail of Amos Gately. He worked secretly, of course, and——”

“And he was kidnaped by Gately’s friends!” I cried; “by some of Rodman’s underlings, and put out of the way! I don’t believe Manning is alive!”

“Go on about the hatpin, Mr. Wise, won’t you?” urged Rivers. “I think I’m going to grow up to be a detective and I’m taking notes.”
