anyone accidentally or purposely to fall.
"I think myself," Waldon remarked to Kennedy, "that it must have been from the open window that she made her way to the outside. It seems that all agree that the door was locked, while the window was wide open."
"There had been no sound--no cry to alarm you?" shot out Kennedy suddenly to Juanita.
"No, sir, nothing. I could not sleep myself, and I thought of Madame."
"You heard nothing?" he asked of Dr. Jermyn.
"Nothing until I heard the maid call," he replied briefly.
Mentally I ran over again Kennedy's first list of possibilities-- taken off by another boat, accident, drugs, suicide, murder.
Was there, I asked myself, sufficient reason for suicide? The letter seemed to me to show too proud a spirit for that. In fact the last sentence seemed to show that she was contemplating the surest method of revenge, rather than surrender. As for accident, why should a person fall overboard from a large houseboat into a perfectly calm harbor? Then, too, there had been no outcry. Somehow, I could not seem to fit any of the theories in with the facts. Evidently it was like many another case, one in which we, as yet, had insufficient data for a conclusion.
Suddenly I recalled the theory that Waldon himself had advanced regarding the wireless, either from the boat itself or from the wireless station. For the moment, at least, it seemed plausible that she might have been seated at the window, that she might have been affected by escaped wireless, or by electrolysis. I knew that some physicians had described a disease which they attributed to wireless, a sort of anemia with a marked diminution in the number of red corpuscles in the blood, due partly to the over etherization of the air by reason of the alternating currents used to generate the waves.
"I should like now to inspect the little wireless plant you have here on the Lucie," remarked Kennedy. "I noticed the mast as we were approaching a few minutes ago."
I had turned at the sound of his voice in time to catch Edwards and Dr. Jermyn eyeing each other furtively. Did they know about the letter, after all, I wondered? Was each in doubt about just how much the other knew?
There was no time to pursue these speculations. "Certainly," agreed Mr. Edwards promptly, leading the way.
Kennedy seemed keenly interested in inspecting the little wireless plant, which was of a curious type and not exactly like any that I had seen before.
"Wireless apparatus," he remarked, as he looked it over, "is divided into three parts, the source of power whether battery or dynamo, the making and sending of wireless waves, including the key, spark, condenser and tuning coil, and the receiving apparatus, head telephones, antennae, ground and detector."
Pedersen, the engineer, came in while we were looking the plant over, but seemed uncommunicative to all Kennedy's efforts to engage him in conversation.
"I see," remarked Kennedy, "that it is a very compact system with facilities for a quick change from one wave length to another."
"Yes," grunted Pedersen, as averse to talking, evidently, as others on the Lucie.
"Spark gap, quenched type," I heard Kennedy mutter almost to himself, with a view to showing Pedersen that he knew something about it. "Break system relay--operator can overhear any interference while transmitting--transformation by a single throw of a six-point switch which tunes the oscillating and open circuits to resonance. Very clever--very efficient. By the way, Pedersen, are you the only person aboard who can operate this?"
"How should I know?" he answered almost surlily.
"You ought to know, if anybody," answered Kennedy unruffled. "I know that it has been operated within the past few days."
Pedersen shrugged his shoulders. "You might ask the others aboard," was all he said. "Mr. Edwards pays me to operate it only for himself, when he has no other operator."
Kennedy did not pursue the subject, evidently from fear of saying too much just at present.
"I wonder if there is anyone else who could have operated it," said Waldon, as we mounted again to the deck.
"I don't know," replied Kennedy, pausing on the way up. "You haven't a wireless on the Nautilus, have you?"
Waldon shook his head. "Never had any particular use for it myself," he answered.
"You say that Miss Verrall and her mother have gone back to the city?" pursued Kennedy, taking care that as before the others were out of earshot.
"Yes."
"I'd like to stay with you tonight, then," decided Kennedy. "Might we go over with you now? There doesn't seem to be anything more I can do here, unless we get some news about Mrs. Edwards."
Waldon seemed only too glad to agree, and no one on the Lucie insisted on our staying.
We arrived at the Nautilus a few minutes later, and while we were lunching Kennedy dispatched the tender to the Marconi station with a note.
It was early in the afternoon when the tender returned with several packages and coils of wire. Kennedy immediately set to work on the Nautilus stretching out some of the wire.
"What is it you are planning?" asked Waldon, to whom every action of Kennedy seemed to be a mystery of the highest interest.
"Improvising my own wireless," he replied, not averse to talking to the young man to whom he seemed to have taken a fancy. "For short distances, you know, it isn't necessary to construct an aerial pole or even to use outside wires to receive messages. All that is needed is to use just a few wires stretched inside a room. The rest is just the apparatus."
I was quite as much interested as Waldon. "In wireless," he went on, "the signals are not sent in one direction, but in all, so that a person within range of the ethereal disturbance can get them if only he has the necessary receiving apparatus. This apparatus need not be so elaborate and expensive as used to be thought needful if a sensitive detector is employed, and I have sent over to the station for a new piece of apparatus which I knew they had in almost any Marconi station. Why, I've got wireless signals using only twelve feet of number eighteen copper wire stretched across a room and grounded with a water pipe. You might even use a wire mattress on an iron bedstead."
"Can't they find out by--er, interference?" I asked, repeating the term I had so often heard.
Kennedy laughed. "No, not for radio apparatus which merely receives radiograms and is not equipped for sending. I am setting up only one side of a wireless outfit here. All I want to do is to hear what is being said. I don't care about saying anything."
He unwrapped another package which had been loaned to him by the radio station and we watched him curiously as he tested it and set it up. Some parts of it I recognized such as the very sensitive microphone, and another part I could have sworn was a phonograph cylinder, though Craig was so busy testing his apparatus that now we could not ask questions.
It was late in the afternoon when he finished, and we had just time to run up to the dock at Seaville and stop off at the Lucie to see if anything had happened in the intervening hours before dinner. There was nothing, except that I found time to file a message to the Star and meet several fellow newspaper men who had been sent down by other papers on the chance of picking up a good story.
We had the Nautilus to ourselves, and as she was a very comfortable little craft, we really had a very congenial time, a plunge over her side, a good dinner, and then a long talk out on deck under the stars, in which we went over every phase of the case. As we discussed it, Waldon followed keenly, and it was quite evident from his remarks that he had come to the conclusion that Dr. Jermyn at least knew more than he had told about the case.
Still, the day wore away with no solution yet of the mystery.
