Burke, who, in the meantime, had been telephoning about the city in a vain effort to locate Baron Kreiger, both at such banking offices in Wall Street as he might be likely to visit and at some of the hotels most frequented by foreigners, merely nodded. He was evidently at a loss completely how to proceed.

In fact, there seemed to be innumerable problems--to warn Baron Kreiger, to get the list of the a.s.sa.s.sinations, to guard Miss Lowe against falling into the hands of her anarchist friends again, to find the murderer of Fortescue, to prevent the use of the electro-magnetic gun, and, if possible, to seize the anarchists before they had a chance to carry further their plans.

"There is nothing more that we can do here," remarked Craig briskly, betraying no sign of hesitation. "I think the best thing we can do is to go to my own laboratory. There at least there is something I must investigate sooner or later."

No one offering either a suggestion or an objection, we four again entered our cab. It was quite noticeable now that the visit had shaken Paula Lowe, but Kennedy still studiously refrained from questioning her, trusting that what she had seen and heard, especially Burke's report as to Baron Kreiger, would have its effect.

Like everyone visiting Craig's laboratory for the first time, Miss Lowe seemed to feel the spell of the innumerable strange and uncanny instruments which he had gathered about him in his scientific warfare against crime. I could see that she was becoming more and more nervous, perhaps fearing even that in some incomprehensible way he might read her own thoughts. Yet one thing I did not detect. She showed no disposition to turn back on the course on which she had entered by coming to us in the first place.

Kennedy was quickly and deftly testing the stub of the little thin, gold-tipped cigarette.

"Excessive smoking," he remarked casually, "causes neuroses of the heart and tobacco has a specific affinity for the coronary arteries as well as a tremendous effect on the vagus nerve. But I don't think this was any ordinary smoke."

He had finished his tests and a quiet smile of satisfaction flitted momentarily over his face. We had been watching him anxiously, wondering what he had found.

As he looked up he remarked to us, with his eyes fixed on Miss Lowe, "That was a ladies' cigarette. Did you notice the size? There has been a woman in this case--presumably."

The girl, suddenly transformed by the rapid-fire succession of discoveries, stood before us like a specter.

"The 'Group,' as anarchists call it," pursued Craig, "is the loosest sort of organization conceivable, I believe, with no set membership, no officers, no laws--just a place of meeting with no fixity, where the comrades get together. Could you get us into the inner circle, Miss Lowe?"

Her only answer was a little suppressed scream. Kennedy had asked the question merely for its effect, for it was only too evident that there was no time, even if she could have managed it, for us to play the "stool pigeon."

Kennedy, who had been clearing up the materials he had used in the a.n.a.lysis of the cigarette, wheeled about suddenly. "Where is the headquarters of the inner circle?" he shot out.

Miss Lowe hesitated. That had evidently been one of the things she had determined not to divulge.

"Tell me," insisted Kennedy. "You must!"

If it had been Burke's bulldozing she would never have yielded. But as she looked into Kennedy's eyes she read there that he had long since fathomed the secret of her wildly beating heart, that if she would accomplish the purpose of saving the Baron she must stop at nothing.

"At--Maplehurst," she answered in a low tone, dropping her eyes from his penetrating gaze, "Professor Annenberg's home--out on Long Island."

"We must act swiftly if we are to succeed," considered Kennedy, his tone betraying rather sympathy with than triumph over the wretched girl who had at last cast everything in the balance to outweigh the terrible situation into which she had been drawn. "To send Miss Lowe for that fatal list of a.s.sa.s.sinations is to send her either back into the power of this murderous group and let them know that she has told us, or perhaps to involve her again in the completion of their plans."

She sank back into a chair in complete nervous and physical collapse, covering her face with her hands at the realization that in her new-found pa.s.sion to save the Baron she had bared her sensitive soul for the dissection of three men whom she had never seen before.

"We must have that list," pursued Kennedy decisively. "We must visit Annenberg's headquarters."

"And I?" she asked, trembling now with genuine fear at the thought that he might ask her to accompany us as he had on our visit to Fortescue's laboratory that morning.

"Miss Lowe," said Kennedy, bending over her, "you have gone too far now ever to turn back. You are not equal to the trip. Would you like to remain here? No one will suspect. Here at least you will be safe until we return."

Her answer was a mute expression of thanks and confidence.

CHAPTER III

THE MURDER SYNDICATE

Quickly now Craig completed his arrangements for the visit to the headquarters of the real anarchist leader. Burke telephoned for a high-powered car, while Miss Lowe told frankly of the habits of Annenberg and the chances of finding his place unguarded, which were good in the daytime. Kennedy's only equipment for the excursion consisted in a small package which he took from a cabinet at the end of the room, and, with a parting rea.s.surance to Paula Lowe, we were soon speeding over the bridge to the borough across the river.

We realized that it might prove a desperate undertaking, but the crisis was such that it called for any risk.

Our quest took us to a rather dilapidated old house on the outskirts of the little Long Island town. The house stood alone, not far from the tracks of a trolley that ran at infrequent intervals. Even a hasty reconnoitering showed that to stop our motor at even a reasonable distance from it was in itself to arouse suspicion.

Although the house seemed deserted, Craig took no chances, but directed the car to turn at the next crossroad and then run back along a road back of and parallel to that on which Annenberg's was situated. It was perhaps a quarter of a mile away, across an open field, that we stopped and ran the car up along the side of the road in some bushes.

Annenberg's was plainly visible and it was not at all likely that anyone there would suspect trouble from that quarter.

A hasty conference with Burke followed, in which Kennedy unwrapped his small package, leaving part of its contents with him, and adding careful instructions.

Then Kennedy and I retraced our steps down the road, across by the crossroad, and at last back to the mysterious house.

To all appearance there had been no need of such excessive caution. Not a sound or motion greeted us as we entered the gate and made our way around to the rear of the house. The very isolation of the house was now our protection, for we had no inquisitive neighbors to watch us for the instant when Kennedy, with the dexterity of a yeggman, inserted his knife between the sashes of the kitchen window and turned the catch which admitted us.

We made our way on cautious tiptoe through a dining room to a living room, and, finding nothing, proceeded upstairs. There was not a soul, apparently, in the house, nor in fact anything to indicate that it was different from most small suburban homes, until at last we mounted to the attic.

It was finished off in one large room across the back of the house and two in front. As we opened the door to the larger room, we could only gaze about in surprise. This was the rendezvous, the a.r.s.enal, literary, explosive and toxicological of the "Group." Ranged on a table were all the materials for bomb-making, while in a cabinet I fancied there were poisons enough to decimate a city.

On the walls were pictures, mostly newspaper prints, of the a.s.sa.s.sins of McKinley, of King Humbert, of the King of Greece, of King Carlos and others, interspersed with portraits of anarchist and anti-militarist leaders of all lands.

Kennedy sniffed. Over all I, too, could catch the faint odor of stale tobacco. No time was to be lost, however, and while Craig set to work rapidly going through the contents of a desk in the corner, I glanced over the contents of a drawer of a heavy mission table.

"Here's some of Annenberg's literature," I remarked, coming across a small pile of ma.n.u.script, ent.i.tled "The Human Slaughter House."

"Read it," panted Kennedy, seeing that I had about completed my part of the job. "It may give a clue."

Hastily I scanned the mad, frantic indictment of war, while Craig continued in his search:

"I see wild beasts all around me, distorted unnaturally, in a life and death struggle, with bloodshot eyes, with foaming, gnashing mouths.

They attack and kill one another and try to mangle each other. I leap to my feet. I race out into the night and tread on quaking flesh, step on hard heads, and stumble over weapons and helmets. Something is clutching at my feet like hands, so that I race away like a hunted deer with the hounds at his heels--and ever over more bodies--breathless...

out of one field into another. Horror is crooning over my head. Horror is crooning beneath my feet. And nothing but dying, mangled flesh!

"Of a sudden I see nothing but blood before me. The heavens have opened and the red blood pours in through the windows. Blood wells up on an altar. The walls run blood from the ceiling to the floor and... a giant of blood stands before me. His beard and his hair drip blood. He seats himself on the altar and laughs from thick lips. The black executioner raises his sword and whirls it above my head. Another moment and my head will roll down on the floor. Another moment and the red jet will spurt from my neck.

"Murderers! Murderers! None other than murderers!"

I paused in the reading. "There's nothing here," I remarked, glancing over the curious doc.u.ment for a clue, but finding none.

"Well," remarked Craig contemplatively, "one can at least easily understand how sensitive and imaginative people who have fallen under the influence of one who writes in that way can feel justified in killing those responsible for bringing such horrors on the human race.

h.e.l.lo--what's this?"

He had discovered a false back of one of the drawers in the desk and had jimmied it open. On the top of innumerable papers lay a large linen envelope. On its face it bore in typewriting, just like the card on the drawer at Fortescue's, "E-M GUN."

"It is the original envelope that contained the final plans of the electro-magnetic gun," he explained, opening it.
