train roared out of the darkness of the tube and Janet saw a sign,
"South Ferry," on the windows.

"This is our train," cried Helen, shoving her companion ahead of her and
into one of the seats. Other passengers piled in, the doors clanged and
they were roaring through the tunnel far under the street level. Their
train was an express and occasionally they shot past a slower local. The
air was close with an odor that is peculiar to a subway, but Janet
enjoyed the ride, watching the crowd in the car. It was evident that
most of them were accustomed to using the subway several times a day and
they were either visiting or reading evening papers, which they had
folded so they would take up the least possible room.

At the South Ferry station they walked up to the street levels and
entered Battery park. Janet paused a moment, struck by the beauty of the
harbor in the late afternoon. Beyond the Battery was the Statue of
Liberty and even further the tidewater flats of Jersey.

Several freighters, which had cleared their docks a few minutes before,
were going down the harbor and Janet and Helen, standing along the
Battery wondered for what distant port they might be bound.

They walked past the Aquarium. On another afternoon they would come back
and spend several hours going through that fascinating building.

"I'm tired," confessed Janet. "Let's get back to the hotel now, clean
up, and have dinner. Perhaps we'll go to a show after that."

Helen readily agreed to the suggestion and they returned to the South
Ferry station where they caught an uptown express that took them to
Times Square at a dizzy pace.

When they emerged from the tube, the shadows were lengthening in the
heart of the city. Sidewalks were crowded with hundreds of men and women
on their way home after a day's work in the city. They paused for
several minutes to watch the teeming mass of humanity and then turned
and entered their hotel.

Janet was the first to step into their rooms and the instant she passed
the threshold a feeling of foreboding gripped her and she stopped so
suddenly that Helen bumped into her.

"What's the matter?" asked Helen, looking up quickly.

Janet looked a little sheepish. "I don't know. For some reason I thought
there was something wrong in here."

"Want me to scream?" smiled Helen. "I can do a good job of that and I
guarantee to get someone here in less than a minute with one scream."

In spite of the banter Janet was far
