very men to run down the big
smuggler I am so anxious to see arrested."

"We'll do our best," said Old King Brady.

The Collector and the inspectors then went away.

As they were leaving the pier, the quick, keen eyes of Harry observed a
young girl on the steamer acting in a mysterious manner.

She was standing in the gangway, peering out one of the port holes and
sharply watching the departing officials.

Every time one of them chanced to glance back, she suddenly dodged down
behind the bulwark out of sight.

She was a beautiful girl of about sixteen, handsomely clad in a short dress
and zouave waist of fine silk, while a stylish big Gainsborough hat with
black ostrich plumes crowned her short, yellow, curly hair.

Her skin was as white as milk and she had a pair of big brown eyes, a
pretty little Grecian nose and rosebud lips.

Young King Brady was charmed with her beauty, yet his suspicions of her
actions were aroused to the fever point.

He touched his partner on the arm and pointed at her.

"See there!" he exclaimed. "What can she be up to?"

"We'd better keep an eye on her, Harry," returned the old detective, after
a careful survey. "It looks to me as if she were up to some trick. She
wouldn't be watching those inspectors' departure that way unless it was of
vital importance to her."

"But surely she can't be so silly as to think there are no officers left
here. Everyone knows that a couple remain constantly on the watch in their
office at the entrance to the dock."

"Ha! What's that? She's waving her handkerchief to that man who is coming
out on the pier from West street."

Young King Brady gazed keenly at the person in question and suddenly
recognizing him he exclaimed in excited tones:

"Why, it's Paul La Croix, the diamond smuggler!"

"So it is, by thunder!"

"And this beautiful girl must be his daughter, for she greatly resembles
him."

"Harry, I believe that pair are up to some crooked work!"

"We can find out by watching them."

La Croix now went aboard the steamer and joined the girl in the gangway.

CHAPTER III.

CAUGHT IN AN ELEVATOR.

The Bradys felt convinced that the smuggler and his daughter were working
some scheme to take some valuables ashore, duty free.

Closely watching the pair they saw them enter the cabin.

Following them in, the Bradys observed the pair gliding swiftly down a
passage, out on which opened the doors of several staterooms.

La Croix and
