A MYSTERY ON BOARD.
Two days later the monotony of the voyage, which was broken only by the
radiograms which were posted daily concerning the race between the
American and British liners--the _Columbia_ being in the lead--was
rudely shattered by an incident in which Jack was destined to play an
important part. Jack had been on a visit to Raynor during the young
engineer's night watch in the engine-room. They had stayed chatting and
talking over old times till Jack suddenly realized that it was long
after midnight and time for him to be in his bunk.
Hastily saying good-night, he made his way through the deserted
corridors of the great ship, which stretched empty and dimly lit before
him. As he traversed them the young wireless man could not but think of
the contrast to the busy life of the day when stewards swarmed and
passengers hurried to and fro. Now everything was silent and deserted,
except for the still figures up on the bridge and below in the engine
and fire rooms, guiding and powering the great vessel onward through the
night at a twenty-four-knot clip.
The lad had just reached the end of one corridor, and was about to turn
into another which led to a companionway, which would bring him to his
own domain, when he stopped short, startled by the sound of a single
sharp outcry. It came from the corridor he was about to turn into. Jack
darted round the corner and almost instantly stumbled over the huddled
body of a man lying outside one of the cabin doors.
A dark stain was under his head, and Jack saw at once that the man had
been the victim of an attack. At almost the same moment, by the dim
light, he recognized the unconscious form as being that of Joseph
Rosenstein, a diamond merchant, so wealthy and famous that he had been
pointed out to Jack by the purser as a celebrity.
"Queer fellow," the purser had said. "Won't put his jewels in the safe,
although I understand he is carrying three magnificent diamonds with
him. Likely to get into trouble if anyone on board knows about it."
"He's taking big chances," agreed Jack, and now here was the proof of
his words lying at the boy's feet. Suddenly he recalled having received
a message a few days before from New York for the injured man.
"Be very careful. F. is on board," it had read, and Jack interpreted
this to be meant as a warning to the diamond merchant. But he did not
devote much attention to it just then, except to rouse the sleepy
stewards. Within a few minutes the captain and the doctor were on the
scene.
"A nasty cut, done with a blackjack or a club," opined Dr. Browning, as
he raised the man.
"Is it a mortal wound?" asked the captain. "This is a terrible thing to
have happen on my ship."
"I think he'll pull through if no complications set in," said the
doctor, and ordered the man removed to his cabin. Suddenly Jack
recollected what the purser had said about the diamonds.
"I beg your pardon, sir," said he to the captain, "but I heard that this
man carried about valuable diamonds with him. He was probably attacked
for purposes of robbery."
"That's right," answered the captain, with a quick look of approval at
Jack. "Browning, we'd better examine the contents of his pockets." They
did so, but no traces of precious stones could be found.
"Whoever did this, robbed him," declared the captain, with a somber
brow, "and the deuce of it is that, unless we can detect him, he will
walk ashore at Southampton or Cherbourg a free man."
The door of the stateroom opposite to which the injured man lay opened
suddenly, and a little, wizen-faced man, wearing spectacles, looked out.
He appeared startled and shocked as he saw the limp form.
"Good gracious! This is terrible, terrible, captain," he sputtered.
"Is--is the man dead?"
"No, Professor Dusenberry, although that does not appear to be the fault
of whoever attacked him," was the rejoinder.
"He was attacked, then, for purposes of robbery, do you think?"
"I suspect so."
"Oh, dear, this has so upset me that I shan't sleep the rest of the
night," protested the little man, and withdrew into his stateroom.
The next day, naturally, the whole ship buzzed with the news of the
night's happenings, and speculation ran rife as to who could have
attacked the diamond merchant, who had recovered consciousness and was
able to talk. He himself had not the slightest idea of his assailant. He
had sat up till late in the smoking saloon, he said, and was coming
along the corridor to his stateroom when he was struck down from behind.
A black leather wallet, containing three diamonds, which were destined
to be sold to the scion of a European royal house, was missing from his
pocket, and the loss nearly drove the unfortunate diamond man frantic.
He valued the stones at $150,000, so that perhaps his frenzy at losing
them was not unnatural.
In the afternoon, Professor Dusenberry, dressed in a frock coat and top
hat, although he was at sea and the weather was warm, came into the
wireless room. He wanted to send a message, he said, a wireless to
London. He was very cautious about inquiring the price and all the
details before he sat down to write out his dispatch. When it was
completed he handed it to Jack with his thin fingers, and asked that it
be dispatched at once. Then he retreated, or rather faded, from the
wireless room. Jack scanned the message with thoughtful eyes. It seemed
an odd radiogram for a college professor, such as he had heard Prof.
Dusenberry was, to be sending. It read as follows:
"Meet me at three on the granite paving-stones. The weather is
fine, but got no specimens. There is no suspicion as you have
directed, but I'm afraid wrong."
F.
"Well, that's a fine muddle for somebody to make out when they get it,"
mused Jack, as he sent out a call for the Fowey Station.
"Must be some sort of a cipher the old fellow is using. He's a dry sort
of old stick. Goodness! How scared he was when he saw that man lying
outside his door. I thought he was going to faint or something."
"Wonder what sort of a cipher that is," mused Jack, as he waited for an
answer to his call. "Looks to me as if it's one of those numerical
ciphers where every second or third or fourth or fifth word is taken
from the context and composes a message. Guess I'll try and work it out
some time. It'll be something to do. And, hullo, he signs himself 'F'."
Jack looked up at the printed passenger-list that hung before him.
"Professor F. Dusenberry" was the last of the "D's"
"His initial," thought Jack, "but it's a funny coincidence that it
should be the same as that of the man the diamond merchant was warned to
watch out for, and that it should have been the professor's door outside
of which he was struck down."
