<h2>CHAPTER IV</h2>
<h3>A PUZZLING MYSTERY</h3></div>
<p>For the second time that evening the radio boys
thought they must be dreaming.</p>
<p>Cassey! Cassey the swindler, whom they had
compelled to make restitution to the victim he
had wronged. Cassey the thug, whom they had
captured in that wild chase after he had looted the
safe and nearly killed the operator in the sending
station. Cassey the convict, who, to their certain
knowledge, had been sentenced to a long term in
prison.</p>
<p>What was Cassey doing over the radio? That
it was that scoundrel they had no doubt. The
stuttering, the tones of the voice, the occasional
whistle which he indulged in in order to go on—all
these things they recognized perfectly. It was
the wildest kind of improbability that he had a
double anywhere who could reproduce him so
perfectly.</p>
<p>Gone now was any thought of the aria from
Lucia. Bob motioned frantically to Jimmy to
hand him a pencil and a sheet of paper. Then he
<span class="pagenum"><SPAN name='page_44' name='page_44'></SPAN>44</span>
jotted down the words, as after great efforts they
fell one by one from the stutterer’s lips. As
Bob did this he bent over the paper in frowning
perplexity. The words themselves were intelligible,
but they did not seem to make sense, nor
was there anywhere a connected sentence.</p>
<p>Finally the stammering voice ceased, and after
they had waited several minutes longer to make
sure that it would not resume, the boys took off
their headphones and gazed at each other in utter
bewilderment.</p>
<p>“Well, I’ll be blessed!” exclaimed Joe. “That
villain Cassey, of all men on the face of the earth!
What do you make of it, Bob?”</p>
<p>“I don’t know what to make of it,” confessed
Bob. “It has simply knocked me endways. I
never thought to hear of that rascal again for the
rest of my life. Yet here he is, less than a year
after he’s been sentenced, talking over the radio.”</p>
<p>“Perhaps he’s received a pardon,” hazarded
Jimmy.</p>
<p>“Not at all likely,” answered Bob. “It isn’t as
though he were a first offender. He’s old in
crime. You remember the raking over the judge
gave him when he sentenced him. Told him if
he had it in his power he’d give him more than
he actually did. No, I think we can dismiss that
idea.”</p>
<p>“Isn’t it possible,” suggested Herb, “that he’s
<span class="pagenum"><SPAN name='page_45' name='page_45'></SPAN>45</span>
employed as radio operator in the prison? He
understands sending and receiving all right.”</p>
<p>“That doesn’t strike me hard either,” Bob objected.
“Likely enough the prison is equipped
with a wireless set, but it isn’t probable that they’d
let a prisoner operate it. It would give him too
good a chance to get in touch with confederates
outside the jail. Then, too, his stuttering would
make him a laughing stock.</p>
<p>“The only explanation that I can see,” he went
on, “is that he’s escaped, and he’s sending this
message on his own hook. Though what the message
is about is beyond me.”</p>
<p>“Just what did you get down?” asked Jimmy
curiously. “I caught a few words, but I don’t remember
them all.”</p>
<p>“It’s a regular hodgepodge,” replied Bob,
spreading out the sheet of paper, while they all
crowded around to read.</p>
<p>“Corn—hay—six—paint—water—slow—sick—jelly,”
read Joe aloud. “Sounds to me like the
ravings of a delirium patient.”</p>
<p>“And yet I’m sure that I got all the words
down right,” said Bob perplexedly. “It must be
a code of some kind. We can’t understand it, and
Cassey didn’t mean that any one should except
some one person whose ear was glued to a radiophone.
But you can bet that that person understood
it all right.”
<span class="pagenum"><SPAN name='page_46' name='page_46'></SPAN>46</span></p>
<p>“I wonder if we couldn’t make it out,” suggested
Herb.</p>
<p>“No harm in trying,” said Joe, “though compared
to this a Chinese puzzle is as simple as
A B C. Let’s take a hack at it, anyhow. We’ll
each take a separate sheet of paper and try to get
something out of it that makes sense.”</p>
<p>For nearly an hour the boys did their best.
They put the words in different orders, read them
forward and backward. But the ideas conveyed
by the separate words were so utterly dissimilar
that they could frame nothing that had the
slightest glimmering of sense and they were finally
compelled to give it up.</p>
<p>“If time were money, we’d spend enough on
this stuff to make us bankrupt,” Joe remarked, in
vast disgust, as he rose to get his cap. “Dan
Cassey was foxy when he made this up. We’ll
have to give the rascal credit for that.”</p>
<p>“Yes,” admitted Herb, “it’s the best kind of a
code. Any one of those words might mean any
one of a hundred thousand things. A man might
spend a lifetime on it and be no nearer success at
the end than he was when he started. The only
way it can be unraveled is by finding the key that
tells what the words stand for. And even that
may not exist in written form. The fellows may
simply have committed them to memory.</p>
<p>“I’ll tell you what I’ll do!” Bob exclaimed.
<span class="pagenum"><SPAN name='page_47' name='page_47'></SPAN>47</span>
“I’ll get the prison to-morrow on the long distance
’phone and ask them about Cassey. I’ll tell them
all about this radio message, and it may be a valuable
tip to them. They may be able to locate the
station from which the messages come, if there
are any more of them. You remember how Mr.
Brandon located Cassey’s sending station the first
time.”</p>
<p>Bob was as good as his word, and got in communication
with the prison just before school
time. The warden was gruff and inclined to be
uncommunicative at first, but his manner changed
remarkably after he heard of the radio message
and he inquired eagerly for the slightest details.</p>
<p>“Yes, Cassey has escaped,” he told Bob. “He
got away about two months ago. He had behaved
himself well for the first six months of his imprisonment,
and we made him a trusty. In that
capacity he had access to various parts of the
prison and occasionally to my own quarters,
which are in a wing connected with the prison.
In some way that hasn’t yet been discovered he
got possession of clothes to cover his prison uniform
and got away one day from the yard in
which he was working. Probably with his help,
two others got away at the same time. Their
names are Jake Raff and Toppy Gillen, both of
them desperate criminals and in for long terms.
Likely enough the three of them are operating together
<span class="pagenum"><SPAN name='page_48' name='page_48'></SPAN>48</span>
somewhere. We made a careful search for
them and have sent out descriptions of them to the
police of all the important cities in the United
States. But this clue of yours is the only one we
have, and it may prove a most important one.
I’ll see that the Federal radio authorities are notified
at once. Keep in touch with me and let me
know if you come across anything else that seems
to point to Cassey. His escape is a sore point
with me, and I’d be glad to have him once more
behind the bars. You can be sure he’ll never get
away again until he’s served out the last day of
his sentence.”</p>
<p>With a warm expression of thanks the warden
hung up his telephone receiver, and Bob hurried
off to school to tell his comrades of what he had
learned.</p>
<p>There was no chance for this, however, before
recess, as he had been kept so long at the telephone
that he was barely able to reach the school before
the bell rang.</p>
<p>When at last he told them of his talk with the
warden, they listened with spellbound interest.</p>
<p>“So the villain managed to escape, did he?”
ruminated Joe. “That’s a black mark against the
warden, and it’s no wonder he’s anxious to get
him back. I’d hate to be in Cassey’s shoes if the
prison gates ever close on him again.”</p>
<p>“You’d think it would be a comparatively easy
<span class="pagenum"><SPAN name='page_49' name='page_49'></SPAN>49</span>
matter to capture him,” suggested Herb. “The
fact that he stutters so badly makes him a marked
man.”</p>
<p>“You can bet that he doesn’t do any more talking
than he can help,” replied Joe. “And, for that
matter, I suppose there are a good many thousand
stutterers in the United States. Almost every
town has one or more. Of course it’s against
him, but it doesn’t by any means make it a sure
thing that he’ll be nabbed.”</p>
<p>Buck Looker and his cronies happened to pass
them in the yard just at that moment and caught
the last word. Buck whispered something to Carl
Lutz, and the latter broke out into uproarious
laughter.</p>
<p>It was so obviously directed against Joe that his
impulsive temper took fire at once. He stepped
up to the trio, despite Bob’s outstretched hand
that tried to restrain him.</p>
<p>“Were you fellows laughing at me?” he asked
of the three, though his eyes were fastened directly
on Buck’s.</p>
<p>“Not especially at you,” returned Buck insolently.
“But at something you said.”</p>
<p>“And what was that?” asked Joe, coming a
step nearer, at which Buck stepped back a trifle.</p>
<p>“About getting nabbed,” he said. “It made
me think of some fellows I know that were
nabbed last night for breaking windows.”
<span class="pagenum"><SPAN name='page_50' name='page_50'></SPAN>50</span></p>
<p>“Oh, that was it!” remarked Joe, with dangerous
calmness while his fist clenched. “Now let
me tell you what it reminds me of. It makes me
think of three cowards who smashed a window
last night with a stone packed in a snowball and
then ran away as fast as their legs could carry
them. Perhaps you’d like me to tell you their
names?”</p>
<p>“I don’t know what you’re talking about,” retorted
Buck, changing color.</p>
<p>“Oh, yes, you do,” replied Joe. “And while
I’m about it, I’ll add that the fellows who smashed
the window were not only cowards, but worse.
And their names are Buck Looker, Carl Lutz and
Terry Mooney.”</p>
<p>“What’s that?” cried Buck, bristling up, while
an angry growl arose from his cronies.</p>
<p>“You heard me the first time,” replied Joe;
“but to get it into your thick heads I’ll say it
again. The cowards, and worse, I referred to
are named Buck Looker, Carl Lutz and Terry
Mooney.”</p>
