Mrs. Ogleby was there, also, and both Kennedy and I watched her curiously. I wondered whether she might not feel just a little relieved to think that Murtha was seemingly out of the way for the present. Her knowledge of the Black Book which had first given the tip to Carton had always been a mystery to Kennedy and was one of the problems which I knew he would like to solve to-night. She was keenly observant of Carton, which led us to suppose that she had not yet got out of her mind the idea that somehow it was he who had been responsible for the detectaphone record which so many of those present were struggling to obtain. Though Langhorne studiously avoided her, I noticed that each kept an eye on the other, and I felt that there was something common to both of them.

It was with an unexpressed air of relief to several members of the party that Miss Ashton at last rapped for order and after a short, pithy, pointed speech of introduction presented the several speakers of the evening. It was, like the audience, a well-balanced programme, which showed the tactfulness and political ac.u.men of Miss Ashton. I shall pa.s.s over the speeches, however, as they had no direct bearing on the mystery which Kennedy and I found so engrossing.

The meeting had been cleverly planned so that in spite of its accomplishing much for the propaganda work of the "cause," it did not become tiresome and the speaking was followed by the entrance of one of the best little orchestras for dance music in the city.

Instantly, the scene transformed itself from a suffrage meeting to a social function that was unique. Leaders of the smart set rubbed elbows, and seemed to enjoy it, with working girls and agitators.

Conservative and radical, millionaire and muckraker succ.u.mbed to the spell of the Ashton hospitality and the lure of the new dances. It was a novel experience for all, a levelling-up of society, as contrasted to some of the levelling-down that we had recently seen.

Kennedy and I, having no mood as things stood for the festivities, drew aside and watched the kaleidoscopic whirl of the dancers. Across from us was a wide doorway that opened into a s.p.a.cious conservatory, a nook of tropical and temperate beauty. Several couples had wandered in there to rest and, as the orchestra struck up something new that seemed to have the "punch" to its timeful measures, they gradually rejoined the dancers.

It had evidently suggested an idea to Kennedy, for a moment later he led me toward the coat room and uncovered the package which he had brought consisting of the two oaken boxes I had seen him adjusting in the laboratory.

We managed to reach the conservatory and found in a corner a veritable bower with a wide rustic seat under some palms. Quickly Kennedy deposited in the shadow of one of them an oaken box, sticking into it the plugs on the ends of the wires that I had brought. It was an easy matter here in the dim half light to conceal the wire behind the plants and a moment later he tossed the end through a swinging window in the gla.s.s and closed the window.

Casually we edged our way out among the dancers and around to the room into which he had thrown the wire. It was a breakfast room, I think, but at any rate we could not remain there for it was quite easy to see into it through the crystal walls of the conservatory. There was, however, what seemed to be a little pantry at the other end, and to this Kennedy deftly led the wires and then plugged them in on the other oaken box.

He turned a lever. Instantly from the wizard-like little box issued forth the strains of the dance music of the orchestra and the rhythmic shuffle of feet. Now and then a merry laugh or a s.n.a.t.c.h of gay conversation floated in to us. Though we were effectually cut off from both sight and hearing in the pantry, it was as though we had been sitting on the rustic bench in the conservatory.

"What is it?" I asked in amazement, gazing at the wonderful little instrument before us.

"A vocaphone," he explained, moving the switch and cutting off the sound instantly, "an improved detectaphone--something that can be used both in practical business, professional, and home affairs as a loud speaking telephone, and, as I expect to use it here, for special cases of detective work. You remember the detectaphone instruments which we have used?"

Indeed I did. It had helped us out of several very tight situations--and seemed now to have been used to get the organization into a very tight political place.

"Well, the vocaphone," went on Kennedy, "does even more than the detectaphone. You see, it talks right out. Those little apertures in the face act like megaphone horns increasing the volume of sound." He indicated the switch with his finger and then another point to which it could be moved. "Besides," he went on enthusiastically, "this machine talks both ways. I have only to turn the switch to that point and a voice will speak out in the conservatory just as if we were there instead of talking here."

He turned the switch so that it carried the sounds only in our direction. The last strains of the dance music were being followed by the hearty applause of the dancers.

As the encore struck up again, a voice, almost as if it were in the little room alongside us, said, "Why, h.e.l.lo, Maty, why aren't you dancing?"

There was an unmistakable air of familiarity about it and about the reply, "Why aren't you, Hartley?"

"Because I've been looking for a chance to have a quiet word with you,"

the man rejoined.

"Langhorne and Mrs. Ogleby," cried Craig excitedly.

"Sh!" I cautioned, "they might hear us."

He laughed. "Not unless I turn the switch further."

"I saw you down at the Criminal Courts Building this morning," went on the man, "but you didn't see me. What did you think of Carton?"

I fancied there was a trace of sarcasm or jealousy in his tone. At any rate, woman-like, she did not answer that question, but went on to the one which it implied.

"I didn't go to see Carton. He is nothing to me, has not been for months. I was only amusing myself when I knew him--leading him on, playing with him, then." She paused, then turned the attack on him.

"What did you think of Miss Ashton? You thought I didn't see you, but you hardly took your eyes off her while I was in the hallway waiting to hear the verdict."

It was Langhorne's turn to defend himself. "It wasn't so much Margaret Ashton as that fellow Carton I was watching," he answered hastily.

"Then you--you haven't forgotten poor little me?" she inquired with a sincere plaintiveness in her voice.

"Mary," he said, lowering his voice, "I have tried to forget you--tried, because I had no right to remember you in the old way--not while you and Martin remained together. Margaret and I had always been friends--but I think Carton and this sort of thing,"--he waved his hand I imagined at the suffrage dancers--"have brought us to the parting of the ways. Perhaps it is better. I'm not so sure that it isn't best."

"And yet," she said slowly, "you are piqued--piqued that another should have won where you failed--even if the prize isn't just what you might wish."

Langhorne a.s.sented by silence. "Hartley," she went on at length, "you said a moment ago you had tried to forget me--"

"But can't," he cut in with almost pa.s.sionate fierceness. "That was what hurt me when I--er--heard that you had gone with Murtha to that dinner of Dorgan's. I couldn't help trying to warn you of it. I know Martin neglects you. But I was mad--mad clean through when I saw you playing with Carton a few months ago. I don't know anything about it--don't want to. Maybe he was innocent and you were tempting him. I don't care. It angered me--angered me worse than ever when I saw later that he was winning with Margaret Ashton. Everywhere, he seemed to be crossing my trail, to be my nemesis. I--I wish I was Dorgan--I wish I could fight."

Langhorne checked himself before he said too much. As it was I saw that it had been he who had told Mrs. Ogleby that the Black Book existed. He had not told her that he had made it, if in fact he had, and she had let the thing out, never thinking Langhorne had been the eavesdropper, but supposing it must be Carton.

"Why--why did you go to that dinner with Murtha?" he asked finally, with a trace of reproach in his tone.

"Why? Why not?" she answered defiantly. "What do I care about Martin?

Why should I not have my--my freedom, too? I went because it was wild, unconventional, perhaps wrong. I felt that way. If--if I had felt that you cared--perhaps--I could have been--more discreet."

"I do care," he blurted out. "I--I only wish I had known you as well as I do now--before you married--that's all."

"Is there no way to correct the mistake?" she asked softly. "Must marriage end all--all happiness?"

Langhorne said nothing, but I could almost hear his breathing over the vocaphone, which picked up and magnified even whispers.

"Mary," he said in a deep, pa.s.sionate voice, "I--I will defend you--from this Murtha thing--if it ever gets out. I know it is always on your mind--that you couldn't keep away from that trial for fear that Carton, or Murtha, or SOMEBODY might say something by chance or drop some hint about it. Trust me."

"Then we can be--friends?"

"Lovers!" he cried fiercely.

There was a half-smothered exclamation over the faithful little vocaphone, a little flurried rustle of silk and a long, pa.s.sionate sigh.

"Hartley," she whispered.

"What is it, Mary?" he asked tensely.

"We must be careful. Carton MUST be defeated. He must not have the power--to use that--record."

"No," ground out Langhorne. "Wait--he shall not. By the way, aren't those orchids gorgeous?"

The encore had ceased and over the vocaphone we could hear gaily chatting couples wandering into the conservatory. The two conspirators rose and parted silently, without exciting suspicion.

For several minutes we listened to s.n.a.t.c.hes of the usual vapid chatter that dancing seems to induce. Then the orchestra blared forth with another of the seductive popular pieces.

Kennedy and I looked at each other, amazed. From the underworld up to the smart set, the trail of graft was the same, debauching and blunting all that it touched. Here we saw the making of a full-fledged scandal in one of the highest circles.

We had scarcely recovered from our surprise at the startling disclosures of the vocaphone, when we heard two voices again above the music, two men this time.

"What--you here?" inquired a voice which we recognized immediately as that of Langhorne.
