had burst with superhuman strength from Burke's grasp and was kneeling by the side of his wife's deathbed.
"It—was all Paula's fault—" gasped the woman. "I—knew I had better—carry it through—like the Fortescue visit—alone."
I felt a sense of reassurance at the words. At least my suspicions had been unfounded. Paula was innocent of the murder of Fortescue.
"Severe, acute nicotine poisoning," remarked Kennedy, as he rejoined us a moment later. "There is nothing we can do—now."
Paula moved at the words, as though they had awakened a new energy in her. With a supreme effort she raised herself.
"Then I—I failed?" she cried, catching sight of Kennedy.
"No, Miss Lowe," he answered gently. "You won. The plans of the terrible gun are destroyed. The Baron is safe. Mrs. Annenberg has herself smoked one of the fatal cigarettes intended for him."
Kreiger looked at us, uncomprehending. Kennedy picked up the crushed, unlighted cigarette and laid it in the palm of his hand beside another, half smoked, which he had found beside Mrs. Annenberg.
"They are deadly," he said simply to Kreiger. "A few drops of pure nicotine hidden by that pretty gilt tip would have accomplished all that the bitterest anarchist could desire."
All at once Kreiger seemed to realize what he had escaped so narrowly. He turned toward Paula. The revulsion of her feelings at seeing him safe was too much for her shattered nerves.
With a faint little cry, she tottered.
Before any of us could reach her, he had caught her in his arms and imprinted a warm kiss on the insensible lips.
"Some water—quick!" he cried, still holding her close.
CHAPTER IV
THE AIR PIRATE
Rounding up the "Group" took several days, and it proved to be a great story for the Star. I was pretty fagged when it was all over, but there was a great deal of satisfaction in knowing that we had frustrated one of the most daring anarchist plots of recent years.
"Can you arrange to spend the week-end with me at Stuyvesant
Verplanck's at Bluffwood?" asked Kennedy over the telephone, the
afternoon that I had completed my work on the newspaper of undoing what
Annenberg and the rest had attempted.
"How long since society took you up?" I asked airily, adding, "Is it a large house party you are getting up?"
"You have heard of the so-called 'phantom bandit' of Bluffwood, haven't you?" he returned rather brusquely, as though there was no time now for bantering.
I confess that in the excitement of the anarchists I had forgotten it, but now I recalled that for several days I had been reading little paragraphs about robberies on the big estates on the Long Island shore of the Sound. One of the local correspondents had called the robber a "phantom bandit," but I had thought it nothing more than an attempt to make good copy out of a rather ordinary occurrence.
"Well," he hurried on, "that's the reason why I have been 'taken up by society,' as you so elegantly phrase it. From the secret hiding-places of the boudoirs and safes of fashionable women at Bluffwood, thousands of dollars' worth of jewels and other trinkets have mysteriously vanished. Of course you'll come along. Why, it will be just the story to tone up that alleged page of society news you hand out in the Sunday Star. There—we're quits now. Seriously, though, Walter, it really seems to be a very baffling case, or rather series of cases. The whole colony out there is terrorized. They don't know who the robber is, or how he operates, or who will be the next victim, but his skill and success seem almost uncanny. Mr. Verplanck has put one of his cars at my disposal and I'm up here at the laboratory gathering some apparatus that may be useful. I'll pick you up anywhere between this and the Bridge—how about Columbus Circle in half an hour?"
"Good," I agreed, deciding quickly from his tone and manner of assurance that it would be a case I could not afford to miss.
The Stuyvesant Verplancks, I knew, were among the leaders of the rather recherche society at Bluffwood, and the pace at which Bluffwood moved and had its being was such as to guarantee a good story in one way or another.
"Why," remarked Kennedy, as we sped out over the picturesque roads of the north shore of Long Island, "this fellow, or fellows, seems to have taken the measure of all the wealthy members of the exclusive organizations out there—the Westport Yacht Club, the Bluffwood Country Club, the North Shore Hunt, and all of them. It's a positive scandal, the ease with which he seems to come and go without detection, striking now here, now there, often at places that it seems physically impossible to get at, and yet always with the same diabolical skill and success. One night he will take some baubles worth thousands, the next pass them by for something apparently of no value at all, a piece of bric-a-brac, a bundle of letters, anything."
"Seems purposeless, insane, doesn't it?" I put in.
"Not when he always takes something—often more valuable than money," returned Craig.
He leaned back in the car and surveyed the glimpses of bay and countryside as we were whisked by the breaks in the trees.
"Walter," he remarked meditatively, "have you ever considered the possibilities of blackmail if the right sort of evidence were obtained under this new 'white-slavery act'? Scandals that some of the fast set may be inclined to wink at, that at worst used to end in Reno, become felonies with federal prison sentences looming up in the background. Think it over."
Stuyvesant Verplanck had telephoned rather hurriedly to Craig earlier in the day, retaining his services, but telling only in the briefest way of the extent of the depredations, and hinting that more than jewelry might be at stake.
It was a pleasant ride, but we finished it in silence. Verplanck was, as I recalled, a large masterful man, one of those who demanded and liked large things—such as the estate of several hundred acres which we at last entered.
It was on a neck of land with the restless waters of the Sound on one side and the calmer waters of the bay on the other. Westport Bay lay in a beautifully wooded, hilly country, and the house itself was on an elevation, with a huge sweep of terraced lawn before it down to the water's edge. All around, for miles, were other large estates, a veritable colony of wealth.
As we pulled up under the broad stone porte-cochere, Verplanck, who had been expecting us, led the way into his library, a great room, literally crowded with curios and objects of art which he had collected on his travels. It was a superb mental workshop, overlooking the bay, with a stretch of several miles of sheltered water.
"You will recall," began Verplanck, wasting no time over preliminaries, but plunging directly into the subject, "that the prominent robberies of late have been at seacoast resorts, especially on the shores of Long Island Sound, within, say, a hundred miles of New York. There has been a great deal of talk about dark and muffled automobiles that have conveyed mysterious parties swiftly and silently across country.
"My theory," he went on self-assertively, "is that the attack has been made always along water routes. Under shadow of darkness, it is easy to slip into one of the sheltered coves or miniature fiords with which the north coast of the Island abounds, land a cut-throat crew primed with exact information of the treasure on some of these estates. Once the booty is secured, the criminal could put out again into the Sound without leaving a clue."
He seemed to be considering his theory. "Perhaps the robberies last summer at Narragansett, Newport, and a dozen other New England places were perpetrated by the same cracksman. I believe," he concluded, lowering his voice, "that there plies to-day on the wide waters of the Sound a slim, swift motor boat which wears the air of a pleasure craft, yet is as black
