n is a desperate man. We have seen
that he would not stop at murder to attain his purposes. When I reach
Montreal, I must telegraph Old King Brady to come on and meet me. He will
be wondering what has become of me now."

When the conductor came through, Harry paid his fare in cash.

A short time afterward one of the girl's male companions made a trip from
one end of the train to the other.

He sharply eyed every passenger on the cars and favored Harry with a
particularly keen and searching stare.

It made the boy imagine for an instant that his identity was known, but he
never flinched.

The man passed on, however, without making any remark.

It took fifteen hours to make the run, and it was three o'clock on the
following afternoon before the train pulled into Montreal.

Shadowing the girl smuggler and her companions, Harry saw them go to a
hotel, where the men left her.

While they went down to the Dominion Line dock, the girl passed into the
hotel and Harry saw her go upstairs.

The hotel clerk, a dudish young fellow, was staring after her when Harry

"That's what I'm going to do. Give me a good room."

"Very well, sir. Got any baggage?"

"None, whatever. I came from Niagara in a hurry."

"You can have No. 37. That's right next to the one occupied by the
beautiful young widow. Perhaps it may lead to your becoming acquainted with
her as you wish."

"I hope so," laughed Harry, who was delighted at his good luck. "Got a
telegraph station here?"

"No. But there's one across the street."

Harry went out and telegraphed to Old King Brady to come and meet him in
Montreal and then went to his room.

While washing, he heard the hum of voices in Clara La Croix's room, and
gliding over to the wall, pressed his ear against the partition.

It was a hollow wall and nearly every word was quite audible.

The first thing he heard was a man's voice which he did not recognize, but
