e just monkey around. It won't take but a few minutes, anyway."

Burke went up to the station with the detective.

They watched patiently when the Chicago train came in, but there was no
sign of the desired visitors. The detective entered the gate, when all
the passengers had left, and searched the train.

"They must have gotten off at One Hundred and Twenty-fifth Street, from
what the conductor could tell me. If they did, then they'll be nabbed
up there, for Sawyer is a wise one, and had that planned," said
Callahan. "I'll just loiter around the station a while to see any
familiar faces. You can go back to your regular post, Burke."

Bobbie bade him good-bye, and started out one of the big entrances. As
he did so he noticed a timid country girl, dressed ridiculously behind
the fashions, and wearing an old-fashioned bonnet. She carried a
rattan suitcase and two bandboxes.

"I wonder if she's lost," thought Burke. "I'll ask her. She looks
scared enough."

He approached the young woman, but before he reached her a well-dressed
young man accosted her. They exchanged a few words, and the fellow
evidently gave her a direction, looking at a paper which she clutched
in her nervous hand. The man walked quickly out of the building toward
the street. Unseen by Burke, he whispered something to another nattily
attired loiterer, an elderly man, who started toward the "car stop."

As Burke rounded the big pillar of the station entrance the man again
addressed the country girl.

"There's your car, sis," he said, with a smile. Bobbie looked at him
sharply.

There was something evil lurking in that smooth face, and the fellow
stared impudently, with the haunting flicker of a scornful smile in his
eyes, as he met the gaze of the policeman.

The country girl hurried toward the north-bound Madison Avenue car,
which she boarded, with several other passengers. Among them was the
gray-haired man who had received the mysterious message.

Burke watched the car disappear, and then turned to look at the smiling
young man, who lit a cigarette, flicking the match insolently near the
policeman's face.

"Move on, you," said Burke, and the young man shrugged his shoulders,
leisurely returning to the waiting room of the station.

Burke was puzzled.

"I wonder what that game was? Maybe I stopped him in time. He looks
like a cadet, I'll be bound. Well, I haven't time to stand around here
and get a reprimand for starting
