"A boy?" queried the man.

"Yes."

"Run into that hallway."

"Ah, there he is! Out with you--aha! I've caught you at last, have I?"
cried the first officer triumphantly.

He seized Frank by the arm and pulled him out on to the sidewalk. The way
he whirled him around amid his wild glee made Frank's teeth chatter.

"Hold on!" our hero demanded, struggling to free himself. "What's all this
about?"

"What's it about, eh?" chuckled his captor. "Mighty innocent, aren't you?
Don't remember me a bit, do you? Look sharp at me, now," rallied the
officer. "I guess you'll recognize me, my soft and downy young bird, if
you'll look hard enough."

"I never saw you before, and you never saw me before," declared Frank,
getting nettled at his rough treatment.

"Thunder! that's so."

The officer, peering closely at Frank, staggered back as though he was
about to collapse. He goggled at Frank, choking with stupefaction and
disappointment.
