The Vanishing Car
Penny fully intended to tell her father of her experience, but she
retired before he came home. She overslept the next morning. When she
descended to the breakfast room at nine o'clock, Mrs. Gallup told her
that the detective had been gone for nearly an hour.
"Your father wasn't in a very good mood this morning," the housekeeper
informed as she served Penny with a steaming hot waffle. "He
complained about the coffee. When he does that it's always because
something's gone wrong with his work."
"You mustn't mind Dad," Penny smiled. "We couldn't get along without
you."
Mrs. Gallup sniffed.
"I do the best I can. The coffee does taste all right, doesn't it?"
"It's perfect."
"When your father's working on a hard case he always likes it strong as
lye," the housekeeper complained. "But I know he was worried about
something this morning."
"What makes you think so?"
"I heard him muttering to himself. Something about the stupidity of
the police. It seems they let some crook get away last night after
your father had laid careful plans to catch him."
"Not Rap Molberg?"
"I think that was the name. Mr. Nichols didn't tell me anything, I
just heard him talking it over with himself."
"It's the only person he will discuss his business with," Penny
chuckled.
After Mrs. Gallup had gone back into the kitchen she mulled over the
information which the housekeeper had given her. It struck her as
probable that the car which she had seen vanish down the dead-end
street had been driven by Rap Molberg or one of his confederates.
"I wish I could have talked with Dad about it before he left the
house," she thought.
Penny had not forgotten her resolution to visit the Hamilton Plant by
daylight. As soon as she had helped Mrs. Gallup with the dishes, she
left the house, walking directly to the scene of the previous evening's
adventure.
The street was deserted. No one questioned her actions as she made a
careful inspection of the old building which had housed the Hamilton
Manufacturing Company until its failure. She examined the walls inch
by inch, but although she was convinced it was there, she could find no
hidden entrance.
Regardless of her failure to find evidence, Penny was unwilling to give
up her original theory. She remained unshaken in her belief that the
mysterious automobile had disappeared into the Hamilton building.
"There's no other place it could have gone," she reasoned. "I'll talk
it over with Dad and see what he thinks."
When she stopped at his office, Mr. Nichols was not there nor could
Miss Arrow tell her when he might return.
The detective did not come home for luncheon and late in the afternoon
telephoned to say that he would take dinner downtown. Rather than
spend an evening alone Penny called Susan, arranging that they should
go to the library together.
The girls spent an hour in the reading room, but for some reason Penny
could not interest herself in the magazines. She kept turning through
them and laying them aside. She felt unusually restless.
Presently an electrical magazine attracted her attention. She glanced
over it carelessly until she came to a particular article which dealt
with photo-electric cells and the clever purposes for which they were
used.
"Why, these 'magic-eyes' are almost human," she commented in an
undertone to Susan. "They turn lights on and off, cook meals, and open
doors, when a beam of light strikes the cell----"
"I've heard of them before," Susan interrupted in a tone which clearly
implied that she was not in the least interested.
Penny took the hint and dropped the subject. But she became absorbed
in the article. When she closed the magazine a half hour later, her
face was flushed with excitement.
"Susan, let's get away from here," she proposed in a whisper. "I've
just had an inspiration!"
Grumbling a little at being forced to leave a fascinating story before
she had finished it, Susan followed her friend from the building.
"What about this inspiration of yours?" she demanded as they walked to
Penny's parked roadster.
"It's this way, Susan. I knew there was a logical explanation for the
mysterious disappearance of that car Rap Molberg was driving. Let's go
over to the Hamilton Factory this minute and test out my new theory."
"You may know what you're talking about, but I'm sure I don't, Penny
Nichols."
"That's because you wouldn't let me tell you about that article I was
reading," Penny laughed. "But I'll explain everything as we go along."
Without pausing to consider that it might not be safe to investigate
the abandoned manufacturing plant at such a late hour, the girls drove
directly into the hilly section of Belton City. Penny turned into the
familiar dead-end street and was relieved to find no sign of other
vehicles.
She halted her roadster at the very end of the pavement in such a
position that the bright headlights played upon the massive walls of
the Hamilton building.
"It must be located higher up," Penny murmured to herself.
"What is?" Susan demanded. "I don't see what you're about anyway."
Without answering, Penny directed the beam of her spotlight upon the
stone structure. Inch by inch she moved it systematically over the
high wall.
"Perhaps it's only a silly idea," she acknowledged at last, "but I
believe that somewhere in the wall there must be a secret door--one
mechanically operated. No doubt the outline of the opening is
disguised by the many irregular cracks in the masonry."
"If you're looking for a secret opening, why not come in the daytime
when you can see much better?"
"I've been here in the daytime and the door can't be detected--at least
not by the eye. I'm hoping to have better luck this time."
"I can't for the life of me see how," Susan began, but ended with a
startled gasp.
A portion of the massive wall was slowly moving backward.
"Just as I thought!" Penny chuckled in delight. "Now we know how Rap
Molberg escaped from the police the other night."
In fascination the girls watched the widening gap in the wall. Soon it
was large enough for an automobile to easily drive through into the
empty building.
"How did you open it?" Susan asked in awe.
"The beam of my spotlight struck a photo-electric cell which was
secreted near the eaves," Penny explained briefly. "You should have
read about it at the library."
"I wish I had now. It's almost uncanny."
"Let's drive in and have a look at the inside," Penny suggested
daringly.
"Won't it be dangerous?" Susan demurred.
"The place seems to be deserted. But probably it would be wiser if you
waited here and I went in alone."
"No, if you're going to risk it, so am I!"
"Then here goes," Penny said.
She drove the roadster through the opening into what appeared to be an
empty room. Curiously, the girls glanced about. Suddenly Susan
uttered a stifled scream.
"The door! It's closing!"
Already the opening had narrowed to a mere slit. It was too late to
retreat.
"Don't lose your nerve," Penny advised, although her own heart was
beating at a furious rate. "We'll find some way to open that door."
"Someone may have seen us drive in and closed it deliberately!"
"I don't think so, Susan. It must have closed automatically."
"Anyway, we're prisoners inside this horrible place! We'll starve to
death before anyone will suspect we're here!"
"I got you into this and I'll get you out," Penny announced firmly.
"There must be some button or lever that opens the door from the
inside."
Although the headlights of the roadster illuminated a portion of the
large room, many of the corners and crannies remained dark. Taking her
flashlight from the pocket of the car, Penny moved cautiously about
searching for some means of escape. Susan remained huddled in her
seat, too terrified to move.
Penny examined the door, but it would not budge when she threw her
weight against it. She could find no lock or catch.
There were several windows high overhead but without a ladder she could
not hope to reach them. She was growing more disturbed than she cared
to admit, when Susan called to her.
"Penny, I think there's some sort of lever over here by the car."
Penny flashed her beam in that direction and was relieved to see that
her chum was right.
"It must operate the door, Susan! We should be out of here in a jiffy!"
Confidently, she grasped the long handle and pulled with all her
strength upon the iron lever.
From below came the low rumble of moving machinery. Penny and Susan
riveted their eyes hopefully upon the door. It did not open.
Instead, a square of floor upon which the roadster was resting, slowly
began to sink.
Uttering a frightened scream, Susan tried to open the car door.
"Save me!" she cried frantically.
Penny leaped nimbly down upon the running board.
"It's all right," she laughed shakily. "We're only descending in an
elevator."
"We'll be killed before we ever get out of this dreadful place!"
The elevator struck the lower floor with a gentle thud. Penny then
climbed into the car and drove it a few feet forward. Relieved of its
weight the platform slowly rose again until it had resumed its former
position.
"We're worse off now than we were before," Susan moaned.
"I think this must be the way out," Penny comforted.
She indicated a tunnel-like opening directly ahead. Susan who had been
looking in the opposite direction had noticed a small room which
appeared to be an office. She called her chum's attention to it.
Together, they cautiously peered inside.
Save for a battered desk and several chairs the tiny room was empty.
Cigarette ashes and old papers were scattered over the floor, giving
evidence that the office had been used recently. Penny tried the desk
and found it locked.
She picked up a few scraps of paper from the floor. They were without
interest.
A folded newspaper lying upon one of the chairs drew her attention.
Opening it, she noticed that an article on the front page had been
underscored with pencil lines. The headline read:
"AUTO ACCESSORY THEFTS
ON STEADY INCREASE HERE"
The story hinted that Belton City police had been unable to cope with
the situation and that local insurance companies long harassed by an
organized gang, had turned the case over to private detectives.
Above the latter statement someone had written the name of Christopher
Nichols in pencil.
Penny carefully folded the newspaper, replacing it upon the chair
exactly as she had found it.
"Let's get away from here before we're caught," she urged. "I suspect
we're in a Molberg hideout."
"Nothing would please me better than to leave this place," Susan
retorted grimly. "Just lead me to an exit."
"I think the tunnel probably will take us out. Come on, let's see."
Returning to the roadster the dark passage seemed forbiddingly
dangerous. Carefully examining the concrete floor, Penny discovered
tire patterns in the dirt. Other cars had used the tunnel.
With the engine at idling speed, they drove into it. The tunnel led
downward at such a steep angle that soon Penny was forced to use her
brakes to keep from going too fast.
"Where will this thing end?" Susan asked.
Even as she spoke they reached level ground. An ordinary double garage
door barred the way. Susan sprang out to open it.
"Why, we're in an empty garage," she announced as she swung back the
door.
Penny drove the roadster through and waited until Susan had closed the
door behind her. Through a plateglass window the girls could now see
the street. But it took them some time to locate another unlocked door
which permitted them to escape.
Once safely out of the building, they pulled up at the side of the road
to take note of their surroundings. At first they could not imagine
where they were.
"Why, this must be Arlington Avenue," Penny decided. "We're several
hundred feet lower than we were when we left that dead-end street on
the hilltop!"
"What a clever means for a crook to escape a police chase!"
"Yes, isn't it? I'm almost certain the place has been used by the
Molberg gang."
"Then we can't get away from here too quick," Susan declared nervously.
Penny laughed.
"We're safe enough now. Besides, I imagine this escape is never used
except in an emergency--probably only when the police are hot on the
trail."
Susan glanced at her watch.
"It's after ten o'clock and I promised mother I'd be back at nine."
"I'll take you straight home," Penny promised. "I don't suppose I need
to mention it, but I think we shouldn't tell anyone about what we
discovered tonight. At least not until the police have been notified."
"Of course not," Susan agreed instantly. "Why don't you have your
father make the report for us?"
"I'd like to handle it that way, if you don't mind," Penny said eagerly.
"Then let's leave it that way. Aside from Mr. Nichols we'll not tell a
soul about our discovery tonight."
A few minutes later the girls took leave of each other. Penny
continued alone toward her own home.
Turning a corner in one of the outlying neighborhood business sections,
she noticed a girl in blue hurrying along the street. Recognizing
Betty Davis, Penny halted her roadster at the curbing.
The girl did not notice for she had paused to stare into the window of
a cafe. A group of young men could be seen within, laughing and
talking.
It was not the type of place frequented by women, and Penny was
astonished when the girl started to open the door. But with her hand
on the knob, Betty Davis seemed to reconsider, for she turned and
walked rapidly away.
Penny drew alongside in her roadster.
"Going my way?" she asked cheerfully. "I'll be glad to give you a
lift."
