"Let me pass!" growled the other in low, ugly tones, as he shot a savage glance at the old detective, and made an effort to go by.

"Wait a moment!" persisted the officer.

"I ain't got any time."

"Tut-tut!"

"Well, what do you want?"

"I've taken a violent interest in your whiskers, sir."

"Come, now, none of your guying——"

"Oh, I ain't fooling. I've taken such a huge interest in your whiskers that I'd like to have a handful as a keepsake."

And so saying the detective grabbed them.

A slight pull dislodged them from the man's face, causing him to recoil, giving utterance to a smothered cry of alarm.
