was no match for her at that game. Would she escape finally, after all?
A sharp report rang out. The Uncas had sent a shot across our bows, so dangerously close that it snapped one of the cables that held the mast.
The vibration of our engine slowed, and ceased, and we lay, idly wallowing in the waves as the revenue cutter, bearing our friend Burke and help, came up.
A couple of boats put out from the cutter and in almost no time we could hear the tread of feet and the exchange of harsh words as the government officers swarmed up the ladder to our deck.
It was only a moment later that the hatch was broken open and we heard the welcome brogue of Burke, calling, "Kennedy—are you and Jameson all right?"
"Right here," sang out Craig, detaching the oscillator and replacing the electric bulb, which he lighted.
The commotion on deck was too great for anyone to make much of finding us, two stowaways. The Countess was surprised, however, and, I felt, rather glad to see us at a time when we might, possibly exert some influence in her favor if matters came to a more serious pass.
There was scarcely time for a word. Burke's men were working quickly. They had entered the hold, after a word from Kennedy, and far out into the ocean they were casting the boxes and bags overboard, one at a time, as fast as they could. They worked feverishly, as Burke spurred them on, and I must say that it was with the utmost relief that I saw the things thrown over.
The boxes sank, but rose again and floated, bobbing up and down, at least some of them, perhaps a third above water and two-thirds below.
It was not for several minutes that I noticed that with those who had come aboard the Furious from the cutter stood Bettina Petzka. A moment later she caught sight of Kennedy.
"Where is my husband?" she demanded, running to him.
Kennedy had no chance to reply.
Suddenly a series of flashes shattered the darkness. A terrific roar seemed to rise from the very ocean, while a rain of sparks lighted up great spurts of water and then fell back, to perish in the dark waves. The Furious trembled from end to end.
We looked, startled, at each other. But we were all safe. The things had been detonated in the water.
"Only the fact that he would have blown himself up prevented him from blowing up the yacht and all the evidence against him, now that we have discovered his plot," cried Burke, excitedly, dashing down the deck.
Recovered scarcely from our surprise at the explosion and the queer actions of the Secret Service man, we rushed after him as best we could, Craig leading.
He led the way to the little wireless room. The door was bolted on the inside, but we managed soon to burst it open.
I shall never forget the surprise which greeted us. In a chair, bound and gagged, as though he had been overcome only after a struggle, sat Petzka.
Mrs. Petzka threw herself frantically on him, tearing at the stout cords that held him.
"Nikola—what is the matter?" she cried. "What has happened?"
Through his gag, which she had loosened a bit, he made a peculiar, gurgling noise. As nearly as I could make out, he was struggling to say, "He came in—surprised me—seized me—locked the door."
Julia Rovigno stood rooted to the spot—utterly speechless.
There, surrounded by electric batteries, condensers, projectors, regulators, resonators, reflectors, voltmeters, and ammeters, queer apparatus which he had smuggled secretly on the Furious, before a strange sort of device, with a wireless headgear still over his ears, stood the owner of at least two of the liners of the belligerents which were to have made the dash for the ocean after he had succeeded by his new wireless ray device in removing the hostile fleet—Count Rovigno himself.
Chapter XIII
The Super-Toxin
"I've got to make good in this Delaney case, Kennedy," appealed our old friend, Dr. Leslie, the coroner, one evening when he had dropped unexpectedly into the laboratory, looking particularly fagged and discouraged.
"You know," he added, "they've been investigating my office—and now, here comes a case which, I must confess, completely baffles us again."
"Delaney," mused Craig. "Let me see. That's the rich Texas rancher who has been blazing a trail through the white lights of Broadway—with that Baroness Von Dorf and——"
"And other war brokers," interrupted Leslie.
"War brokers?" queried Craig.
"Yes. That's what they call them. They're a new class—people with something to sell to or with commissions to buy for belligerent governments. In Delaney's case it was fifty thousand or so head of cattle and horses, controlled by a syndicate of which he was the promoter. That's why he came to New York, you know,—to sell them at a high price to any European power. The syndicate stands to make a small fortune."
"I understand," nodded Kennedy, interested.
"Just as though there wasn't mystery enough about Delaney's sudden death," Leslie hurried on, "here's a letter that came to him today—too late."
Kennedy took the note Leslie handed him. It was postmarked "Washington," and read:
Dear Daley:
I intended writing to you sooner but haven't felt well enough since I came here. The strangest thing about it is that the doctors I have consulted seem to be unable to tell me definitely what is the matter.
I can tell you I have been badly frightened. I seemed to have a lot of little boils on my face and new ones kept coming. I felt weak and chilly and had headaches that almost drove me crazy. Perhaps the thing, whatever it is, has made me insane, but I cannot help wondering whether there may not be something back of it all. Do you suppose someone could have poisoned me, hoping to ruin my beauty, on which, to a great measure, depends my success in my mission to America during the war?
Since I came here I have been wondering, too, how you are. If there should be anything in my suspicions, perhaps it would be safest for you to leave New York. There is nothing more I can say, but if you feel the least bit unwell, do not disregard this warning.
If you will meet me here, we can arrange the deal with those I represent at almost any price you name.
Try hard to get here.
As ever,
Louise.
Craig looked up quickly. "Have you communicated with the Baroness?" he asked.
Dr. Leslie leaned forward in his chair. "The fact is," he replied slowly, "the woman who calls herself the Baroness Von Dorf has suddenly disappeared, even in Washington. We can find no trace of her whatever. Indeed, the embassy down there does not even admit that she is a war buyer. Oh, the newspapers haven't got the whole Delaney story—yet. But when they do get it"—he paused and glanced significantly at me—"there's going to be some sensation."
I recalled now that there had been an air of mystery surrounding the sudden death of Daley Delaney the day before. At least one of the papers had called it "the purple death"—whatever that might mean. I had thought it due to the wild career of the ranchman, perhaps a plain case of apoplexy, around which the bright young reporters had woven a slender thread of romance. Kennedy, however, thought otherwise.
"The purple death," he ruminated, turning the case over in his mind. "Have you any idea what the papers mean by that?"
"Why, it's one of the most grewsome things you ever heard of," went on Leslie eagerly, encouraged. "In some incomprehensible way the hand of fate seems to have suddenly descended on the whole Delaney entourage. First his Japanese servant fell a victim to this 'purple death,'
