of themselves. But in the presence of the tragedy and a danger which she felt but could not seem to define, she felt the need of outside assistance and did not hesitate to ask it. Nor was Kennedy slow in responding. He seemed to welcome a chance to help some one in distress.
We found Everson and his young wife at the hotel, quite different now from the care-free adventurers who had set out only a few days before to wrest a fortune from chance.
I had often seen portraits of the two Sanford sisters in the society pages of the papers in the States and knew that the courtship of Orrin Everson and Asta Sanford had been a true bit of modern romance.
Asta Everson was a unique type of girl. She had begun by running fast motor cars and boats. That had not satisfied her, and she had taken up aviation. Once, even, she had tried deep-sea diving herself. It seemed as if she had been born with the spirit of adventure.
To win her, Everson had done about everything from Arctic exploration one summer when he was in college to big-game hunting in Africa, and mountain-climbing in the Andes. Odd though the romance might seem to be, one could not help feeling that the young couple were splendidly matched in their tastes. Each had that spirit of restlessness which, at least, sent them out playing at pioneering.
Everson had organized the expedition quite as much in the spirit of revolt against a prosaic life of society at home as for gain. It had appealed strongly to Asta. She had insisted that nothing so much as a treasure hunt would be appropriate for their wedding-trip and they had agreed on the unconventional. Accordingly, she and her sister had joined Everson and his party, Norma, though a year younger, being quite like her sister in her taste for excitement.
“Of course, you understand,” explained Everson, as he hurriedly tried to give us some idea of what had happened, “we knew that the Antilles had sunk somewhere off the Cay d’Or. It was first a question of locating her. That was all that we had been doing when Bertram died. It is terrible, terrible. I can’t believe it. I can’t understand it.”
In spite of his iron nerve, the tragedy seemed to have shaken Everson profoundly.
“You had done nothing that might have been dangerous?” asked Kennedy, pointedly.
“Nothing,” emphasized Everson. “You see, we located the wreck in a way somewhat similar to the manner in which they sweep the seas for mines and submarines. It was really very simple, though it took us some time. All we did was to drag a wire at a fixed depth between the yacht and the tug, or rather, I suppose you’d almost call it a trawler, which I chartered from Havana. What we were looking for was to have the wire catch on some obstruction. It did, too, not once, but many times, due to the unevenness of the ocean bed. Once we located a wreck, but it was in shallow water, a small boat, not the one we were looking for.”
“But you succeeded finally?”
“Yes, only day before yesterday we located her. We marked the spot with a buoy and were getting ready for real work. It was just after that that Bertram was taken ill and died so suddenly. We’ve left Dominick, Kinsale, Gage, and the rest on the trawler there, while I came here with Traynor’s body. God! but it was awful to have to send the news back to New York. I don’t know what to think or what to do.”
“How did he die?” asked Kennedy, endeavoring to gain the confidence of young Everson. “Do you recall any of his symptoms?”
“It came on him so suddenly,” he replied, “that we hadn’t much time to think. As nearly as we could make out, it began with a faintness and difficulty in breathing. We asked him how he felt—but it seemed as if he was deaf. I thought it might be the ‘bends’—you know, caisson disease—and we started to put him in the medical lock which we had for the divers, but before we could get it ready he was unconscious. It was all so sudden that it stunned us. I can’t make it out at all.”
Neither Asta nor Norma seemed able to tell anything. In fact, the blow had been so swift and unexpected, so incomprehensible, that it had left them thoroughly alarmed.
The body of Traynor had already been brought ashore and placed in a local undertaking shop. With Everson, Kennedy and I hastened to visit it.
Traynor had been an athlete and powerfully built, which made his sudden death seem all the more strange. Without a word, Craig set to work immediately examining his body, while we stood aside, watching him in anxious silence. Kennedy consumed the greater part of the morning in his careful investigation, and after some time Everson began to get restless, wondering how his wife and sister-in-law were getting on in his absence. To keep him company I returned to the hotel with him, leaving Kennedy to pursue his work alone.
There was nothing much that either of us could say or do, but I thought I observed, on closer acquaintance with Norma, that she had something weighing on her mind. Was it a suspicion of which she had not told us? Evidently she was not prepared to say anything yet, but I determined, rather than try to quiz her, to tell Kennedy, in the hope that she might confide in him what she would not breathe to any one else.
It was perhaps an hour or more later that we returned to Craig. He was still at work, though from his manner it was evident that his investigations had begun to show something, however slight.
“Have you found anything?” asked Everson, eagerly.
“I think I have,” returned Craig, measuring his words carefully. “Of course you know the dangers of diving and the view now accepted regarding the rapid effervescence of the gases which are absorbed in the body fluids during exposure to pressure. I think you know that experiment has proved that when the pressure is suddenly relieved the gas is liberated in bubbles within the body. That is what seems to do the harm. His symptoms, as you described them, seemed to indicate that. It is like charged water in a bottle. Take out the cork and the gas inside which has been under pressure bubbles up. In the human body, air and particularly the nitrogen in the air, literally form death bubbles.”
Everson said nothing as he regarded Kennedy’s face searchingly, and Craig went on: “Set free in the spinal cord, for instance, such bubbles may cause partial paralysis, or in the heart may lead to stoppage of the circulation. In this case I am quite sure that what I have found indicates air in the arteries, the heart, and the blood vessels of the brain. It must have been a case of air embolism, insufflation.”
Though Everson seemed all along to have suspected something of the sort, Kennedy’s judgment left him quite as much at a loss for an explanation. Kennedy seemed to understand, as he went on:
“I have tried to consider all the ways such a thing could have happened,” he considered. “It is possible that air might have been introduced into the veins by a hypodermic needle or other instrument. But I find no puncture of the skin or other evidence that would support that theory. I have looked for a lesion of the lungs, but find none. Then how could it have occurred? Had he done any real deep diving?”
Everson shook his head slowly. “No,” he replied. “As I said, it wouldn’t have been so incomprehensible if he had. Besides, if we had been diving, we should have been on the lookout. No, Bertram had only tested the apparatus once, after we located the wreck. He didn’t much more than go under the surface—nothing like the practice dives we all made up in Long Island Sound before we came down here. He was only testing the pumps and other things to see whether they had stood the voyage. Why, it was nothing at all! I don’t see how it could have given any one the ‘bends’—much less a fellow like Traynor. Why, I think he could have stood more than Kinsale with a little practice. Kennedy, I can’t get it out of my mind that there’s something about this that isn’t RIGHT.”
Craig regarded Everson gravely. “Frankly,”
