THE PHOTO TELEPHONE
Tom Swift was taking, as he afterward
confessed, “a mighty big chance.”
But it seemed the only way. He was working against
cunning men, and had to be as cunning as they.
True, the man he hoped to capture,
through the combination of his photo telephone and
the phonograph, might go to some other instrument
than one of those Tom had adjusted. But this could
not be helped. In all he had put his new attachment
on eight ’phones in the vicinity of the sawmill.
So he had eight chances in his favor, and as many
against him as there were other telephones in use.
“It’s a mighty small margin
in our favor,” sighed Tom.
“It sure is,” agreed Ned.
They were at Mrs., Damon’s house, waiting for
the call to come in.
“But we couldn’t do anything else,”
went on Tom.
“No,” spoke Ned, “and
I have a great deal of hope in the proverbial Swift
luck, Tom.”
“Well, I only hope it holds
good this time!” laughed the young inventor.
“There are a good many things
that can go wrong,” observed Ned. “The
least little slip-up may spoil your traps, Tom.”
“I know it, Ned. But I’ve
got to take the chance. We’ve just got
to do something for Mrs. Damon. She’s wearing
herself out by worrying,” he added in a low
voice, for indeed the wife of his friend felt the
absence of her husband greatly. She had lost
flesh, she ate scarcely anything, and her nights were
wakeful ones of terror.
“What if this fails?” asked Ned.
“Then I’m going to work
that button clue to the limit,” replied Tom.
“I’ll go to Boylan and see what he and
Peters have to say.”
“If you’d done as I suggested
you’d have gone to them first,” spoke
Ned. “You’ll find they’re mixed
up in this.”
“Maybe; but I doubt it.
I tell you there isn’t a clue leading to Peters—as
yet.”
“But there will be,” insisted
Ned. “You’ll see that that I’m
right this time.”
“I can’t see it, Ned.
As a matter of fact, I would have gone to Boylan about
that button I found in my airship only I’ve been
so busy on this photo telephone, and in arranging
the trap, that I haven’t had time. But
if this fails—and I’m hoping it won’t—I’ll
get after him,” and there was a grim look on
the young inventor’s face.
It was wearying and nervous work—this
waiting. Tom and Ned felt the strain as they
sat there in Mrs. Damon’s library, near the
telephone. It had been fitted up in readiness.
Attached to the receiving wires was a sensitive plate,
on which Tom hoped would be imprinted the image of
the man at the other end of the wire—the
criminal who, in exchange for the valuable land papers,
would give Mr. Damon his liberty.
There was also the phonograph cylinder
to record the man’s voice. Several times,
while waiting for the call to come in, Tom got up
to test the apparatus. It was in perfect working
order.
As before, there was an extension
telephone, so that Mrs. Damon could talk to the unknown,
while Tom could hear as well. But he planned
to take no part in the conversation unless something
unforeseen occurred.
Mr. Damon was an enthusiastic photographer,
and he had a dark room adjoining his library.
It was in this dark room that Tom planned to develop
the photo telephone plate.
On this occasion he was not going
to use the metal plate in which, ordinarily, the image
of the person talking appeared. That record was
but a fleeting one, as in a mirror. This time
Tom wanted a permanent picture that could, if necessary,
be used in a court of justice.
Tom’s plan was this: If
the person who had demanded the papers came to one
of the photo telephones, and spoke to Mrs. Damon, Tom
would switch on the receiving apparatus. Thus,
while the man was talking, his picture would be taken,
though he would not know of the thing being done.
His voice would also be recorded on
the wax cylinder, and he would be equally unaware
of this.
When Tom had imprinted the fellow’s
image on the prepared plate, he would go quickly to
the dark room and develop it. A wet print could
be made, and with this as evidence, and to use in
identification, a quick trip could be made to the place
whence the man had telephoned. Tom hoped thus
to capture him.
To this end he had his airship in
waiting, and as soon as he had developed the picture
he planned to rush off to the vicinity of the sawmill,
and make a prisoner of the man whose features would
be revealed to him over the wire.
It was a hazardous plan—a
risky one—but it was the best that he could
evolve. Tom had instructed Mrs. Damon to keep
the man in conversation as long as possible, in order
to give the young inventor himself time to rush off
in his airship. But of course the man might get
suspicious and leave. That was another chance
that had to be taken.
“If I had thought of it in time,”
said Tom, musingly, as he paced up and down in the
library waiting for the ’phone to ring, “if
I had thought of it in time I would have rigged up
two plates—one for a temporary, or looking-glass,
picture, and the other for a permanent one. In
that way I could rush off as soon as I got a glimpse
of the fellow. But it’s too late to do that
now. I’ll have to develop this plate.”
Waiting is the most wearisome work
there is. Tom and Ned found this to be the case,
as they sat there, hoping each moment that the telephone
bell would ring, and that the man at the other end
of the wire would be the mysterious stranger.
Mrs. Damon, too, felt the nervous strain.
“This is about the hour he called
up yesterday,” said Tom, in a low voice, after
coming back from a trip to the window to see that
his airship was in readiness. He had brought over
to help in starting it, for he was using his most
powerful and speedy craft, and the propellers were
hard to turn.
“Yes,” answered Mrs. Damon.
“It was just about this hour, Tom. Oh,
I do hope—”
She was interrupted by the jingle
of the telephone bell. With a jump Tom was at
the auxiliary instrument, while Mrs. Damon lifted
off the receiver of her own telephone.
“Yes; what is it?” she
asked, in a voice that she tried to make calm.
“Do you know who this is?”
Tom heard come over the wire.
“Are you the—er—the
person who was to give me an address where I am to
send certain papers?”
“Yes. I’m the same
one. I’m glad to see that you have acted
sensibly. If I get the papers all right, you’ll
soon have your husband back. Now do as I say.
Take down this address.”
“Very well,” assented
Mrs. Damon. She looked over at Tom. He was
intently listening, and he, too, would note the address
given. The trap was about to be sprung.
The game had walked into it. Just which telephone
was being used Tom could not as yet tell. It was
evidently not the one nearest the planing mill, for
Tom could not hear the buzzing sound. It was
well he had put his attachment on several instruments.
“One moment, please,”
said Mrs. Damon, to the unknown at the other end of
the wire. This was in accordance with the pre-arranged
plan.
“Well, what is it?” asked
the man, impatiently. “I have no time to
waste.”
Tom heard again the same gruff tones,
and he tried in vain to recognize them.
“I want you take down a message
to Mr. Damon,” said his wife. “This
is very important. It can do you no harm to give
him this message; but I want you to get it exact.
If you do not promise to deliver it I shall call all
negotiations off.”
“Oh, all right I’ll take
the message; but be quick about it. Then I’ll
give you the address where you are to send the papers.”
“This is the message,”
went on Mrs. Damon. “Please write it down.
It is very important to me. Have you a pencil?”
“Yes, I have one. Wait
until I get a bit of paper. It’s so dark
in this booth—wait until I turn on the
light.”
Tom could not repress a pleased and
joyful exclamation. It was just what he had hoped
the man would do—turn on the light in the
booth. Indeed, it was necessary for the success
of the trap that the light be switched on. Otherwise
no picture could be transmitted over the wire.
And the plan of having the man write down a message
to Mr. Damon was arranged with that end in view.
The man would need a light to see to write, and Tom’s
apparatus must be lighted in order to make it work.
The plot was coming along finely.
“There!” exclaimed the
man at the other end of the wire. “I have
a light now. Go ahead with your message, Mrs.
Damon. But make it short. I can’t
stay here long.”
Then Mrs. Damon began dictating the
message she and Tom had agreed upon. It was as
long as they dared make it, for they wanted to keep
the man in the booth to the last second.
“Dear Husband,” began
Mrs. Damon. What the message was does not matter.
It has nothing to do with this story. Sufficient
to say that the moment the man began writing it down,
as Tom could tell over the sensitive wire, by the
scratching of the pencil—at that moment
Tom, knowing the light was on in the distant telephone
booth, switched on the picture-taking apparatus.
His receiving apparatus at once indicated that the
image was being made on the sensitive plate.
It took only a few seconds of time,
and with the plate in the holder Tom hastened to the
dark room to develop it. Ned took his chum’s
place at the telephone, to see that all worked smoothly.
The photo telephone had done it’s work.
Whose image would be found imprinted on the sensitive
plate? Tom’s hands trembled so that he
could scarcely put it in the developing solution.
