"Is everything all right?" whispered one, a new voice which was somewhat familiar I thought, but disguised beyond recognition.
"Yes. She"ll be out in a minute."
"Now, remember what I told you. If this thing works you get fifty dollars more. I"d better put this mask on--d.a.m.n it!--the slit"s torn.
It"ll do. I"ll hide here as soon as we hear her. That"s a pretty nice private ambulance you have down there. Did you tell the elevator boy that she had suddenly been taken ill? That"s all fixed, then. I"ve got the stuff--amyl nitrite--she"ll go off like a shot. But we"ll have to work quick. It only keeps her under a few minutes. I can"t wear this mask down and I"m afraid some one will recognize me. Oh, you brought a beard. Good. I"ll give you the signal. There must be no noise. Yes, I saw the stretcher where you left it in the hall."
"All right, Doc," returned the first and unfamiliar voice.
It all happened so quickly that we were completely bowled over for the moment. Who was the man addressed as "Doc"? There was no time to find out, no time to do anything, apparently, so quickly had the plot been sprung.
I looked at Kennedy, aghast, not knowing what to do in this unexpected crisis.
A moment later we heard a voice, "I"m sorry to have had to keep you waiting, but what is it that I can do for you?"
"Good G.o.d!" exclaimed Kennedy. "It is Inez herself!"
It was altogether too late to get over there to warn her, perhaps even to rescue her. What could we do? If we could only shout for help. But what good would that do, around a corner and so far away?
The vocaphone itself!
Quickly Kennedy turned another switch, of a rheostat, which accentuated a whisper to almost a shout.
"Don"t be alarmed, Senorita," he cried. "This is Kennedy talking. Look under the bookcase by the window. You will find a cedar box. It is a detective vocaphone through which I can hear you and which is talking out to you. I have heard something just there just now--"
"Yes, yes. Go on!"
"You are threatened. Shout! Shout!"
Just then there came a sound of a scuffle and a m.u.f.fled cry which was not much above a whisper, as though a strong hand was clapped over her mouth.
What could we do?
"Juanita--Juanita--help!--police!" shouted Craig himself through the vocaphone.
An instant later we could hear other screams as Juanita heard and spread the alarm, not a second too soon.
"Come on, Walter," shouted Kennedy dashing out of the room, now that he was a.s.sured the alarm had been given.
We hurried around the corner, and into the apartment. One of the elevators was up, and no one was running the other, but we opened the gates and Kennedy ran it up by himself.
In the Mendoza apartment all was a babel of voices, every one talking at once.
"Did you get them?" Craig asked, looking about.
"No, sir," replied the elevator boy. "One of them came in from the ambulance and told me Miss Mendoza was suddenly taken sick. He rode up with the stretcher. The other one must have walked up."
"Do you know him? Has he ever been here before?"
"I can"t say, sir. I didn"t see him. At least, sir, when I heard the screams I ran in from the elevator, which the other one told me to wait with--left the door open. Just as I ran in, they dodged out past me, jumped into the car and rode down. I guess they must have had the engine of the ambulance motor running, sir, if they got away without you seeing them."
We were too late to head them from speeding off. But, at least, we had saved the Senorita. She was terribly upset by the attack, much shaken, but really all right.
"Have you any idea who it could be?" asked Craig as the faithful Juanita cared for her.
"I don"t know the man who was waiting and "Nita never saw him, either,"
she replied. "The one who jumped out from behind the portieres had on a mask and a false beard. But I didn"t recognize anything about him."
Sudden as the attack had been and serious as might have been the outcome, we could not but feel happy that it had been frustrated.
Yet it seemed that some one ought to be delegated to see that such a thing could not occur again.
"We must think up some means of protecting you," soothed Kennedy. "Let me see, Mr. Lockwood and Mr. Whitney seem to be the closest to you. If you don"t mind I"ll call them up. I wonder if you"d object if we had a little luncheon up here, to-morrow? I have a special reason for asking it. I want to insure your safety and we may as well meet on common ground."
"There isn"t the slightest objection in the world," she replied, as Kennedy reached for the telephone.
We had some little difficulty in locating both Lockwood and Whitney, but finally after a time managed to find them and arrange for the conference on the Senorita"s safety for the next day.
Outside Kennedy gave instructions to the officer on the beat to watch the apartment particularly, and there was no reason now to fear a repet.i.tion of the attempt, at least that night.

THE ANTIDOTE
Early the following morning Kennedy left me alone in the laboratory and made a trip downtown, where he visited a South American tobacco dealer and placed a rush order for a couple of hundred cigarettes exactly similar in shape and quality to those which Mendoza had smoked and which the others seemed also to prefer, except, however, that the deadly drug was left out.
While he was gone, it occurred to me to take up again the hunt for Alfonso. Norton was not in his little office, nor could I find Alfonso anywhere about the campus. In fact he seemed to have almost dropped out of his University work for the time. Accordingly, I turned my steps toward the Prince Edward Albert Hotel, in the hope that he might be there.
Inquiries of the clerk at the desk told me that he had been there, but was out just at that moment. I did not see Whitney around, nor the Senora, so I sat down to wait, having nothing better to do until Kennedy"s return.
I was about to give it up and go, when I heard a cab drive up to the door and, looking up, I saw Alfonso get out. He saw me about the same time and we bowed. I do not think he even tried to avoid me.
"I haven"t seen you for some time," I remarked, searching his face, which seemed to me to be paler than it had been.
"No," he replied. "I haven"t been feeling very well lately and I"ve been running up into the country now and then to a quiet hotel--a sort of rest cure, I suppose you would call it. How are you? How is Senorita Inez?"
"Very well," I replied, wondering whether he had said what he did in the hope of establishing a complete alibi for the events of the night before.
Briefly I told him what had happened, omitting reference to the vocaphone and our real part in it.
"That is terrible," he exclaimed. "Oh, if she would only allow me to take care of her--I would take her back to our own country, where she would be safe, far away from these people who seek to prey on all of us."
He paced up and down nervously, and I could see that my information had added nothing to his peace of mind, though, at the same time, he had betrayed nothing on his part.
"I was just pa.s.sing through," I said finally, looking at my watch, "and happened to see you. I hope your mother is well?"
