Citadel. We can get to the Hotel in five minutes."
* * * * *
It was a flight of only half an hour. During it, Alan told me about Polter. The hunchback, known now as Frank Rascor, owned a mine in the Laurentians, some thirty miles from Quebec City—a fabulously productive mine of gold. It was an anomaly that gold should be produced in this region. No vein of gold-bearing rock had been found, except the one on Polter's property. Alan had seen a newspaper account of the strangeness of it; and on a hunch had come to Quebec, being intrigued by the description of the mine owner. He had seen Frank Rascor on the Dufferin Terrace, and recognized him as Polter.
Again my thoughts went back into the past. Had Polter stolen that missing fragment of golden quartz the size of a walnut which had been beneath Dr. Kent's microscope? We always thought so. Dr. Kent had some secret, some great problem upon which he was working. Polter, his assistant, had evidently known, or partially known, its details. And now, four years later, Polter was immensely rich, with a "gold mine" in mountains where there was no other evidence of gold!
I seemed to see some connection. Alan, I knew, was groping with a dim idea, so strange he hardly dared voice it.
"I tell you, it's weird, George. The sight of him. Polter—heavens, one couldn't mistake that build—and his face, his features, just the same as when we knew him."
"Then what's so weird?" I demanded.
"His age." There was a queer solemn hush in Alan's voice. "George, when we knew Polter, he was about twenty-five, wasn't he? Well, that was four years ago. But he isn't twenty-nine now. I swear it is the same man, but he isn't around thirty. Don't ask me what I'm talking about. I don't know. But he isn't thirty. He's nearer fifty! Unnatural! Weird! I felt it, and so did Babs, just that brief look we had of him."
I didn't answer. My attention was on managing the plane. The lights of Levis were under us. Beyond the City cliffs, the St. Lawrence lay in its deep valley; the Quebec lights, the light-dotted ramparts with the Terrace and the great fortresslike Hotel showed across the river.
"Better take the stick, Alan. I don't know where the field is. And don't you worry about Babs. She'll be back by now."
* * * * *
But she was not. We went to the two connecting rooms in the tower of the Hotel which Alan and Babs had engaged. We inquired with half a dozen phone calls. No one had seen or heard from her. The Quebec police were sending a man up to talk with Alan.
"Well, we won't be here," Alan called to me. He was standing by the window in Babs' room; he was trembling too much to use the phone. I hung up the receiver and went though the connecting door to join him.
Babs' room! It sent a pang through me. A few of her garments were lying around. A negligee was laid out on the large bed. A velvet boudoir doll—she had always loved them—stood on the dresser. Upon this Hotel room, in one day, she had impressed her personality. Her perfume was in the air. And now she was gone.
"We won't be here," Alan was repeating. He gripped me at the window. "Look." In his hand was an ugly-looking, smokeless, soundless automatic of the Essen type. "And I've got another one for you. Brought them with me."
His face was white and drawn, but his hands had steadied. The tremble was gone out of his voice.
"I'm going after him, George! Now! Understand that? Now? His place is only thirty miles from here, out there in the mountains. You can see it in the daylight—a wall around his property and a stone castle which he built in the middle of it. A gold mine? Hell!"
There was nothing to be seen now out of the window but the snow-filled darkness, the blurred lights of Lower Quebec and the line of dock lights five hundred feet below us.
"Will you fly me, George?"
"Of course."
I was the one trembling now; the cool feel of the automatic which Alan thrust into my hand seemed suddenly to crystallize Babs' peril. I was here in her room, with the scent of her perfume around me, and this deadly weapon was needed! But the trembling was gone in a moment.
"Yes, of course, Alan. No use talking to the police. I gave them all the information—a description of her, what you said she was wearing. No sense dragging Polter's name into it, with nothing tangible to go on. The police won't ransack the castle of a rich man just because you can't find your sister. Come on. You can tell me what this place is like as we go."
* * * * *
Bundled in our flying suits we hurried from the Hotel, climbed the Citadel slope and in ten minutes were in the air. The wind sucked at us. The snow now was falling with thick, huge flakes. Directed by Alan, I headed out over this ice-filled St. Lawrence, past the frozen Ile d'Orleans, toward Polter's mysterious mountain castle.
Suddenly Alan burst out, "I know what father's secret was! I can piece it together now, from little things that were meaningless when I was a kid. He invented the electro-microscope. You know that. The infinitely small fascinated him. I remember he once said that if we could see far enough down into smallness, we would come upon human life!"
Alan's low, tense voice was more vehement than I had ever heard it before. "It's clear to me now, George. That little fragment of golden quartz which he wanted me to be so careful of contained a world with human inhabitants! Father knew it, or suspected it. And I think the chemical problem on which he was working aimed for some drug. I know it was a drug they were compounding, Polter said so once, a radioactive drug; I remember listening at the door. A drug, George, capable of making a human being infinitely small!"
I did not answer when momentarily Alan paused. So strange a thing. My mind whirled with it; struggled to encompass it. And like the meaningless individual pieces of a puzzle, dropping so easily into place when the key piece is fitted, I saw Polter stealing that fragment of gold; abducting Dr. Kent—perhaps because Polter himself was not fully acquainted with the secret. And now, Polter up here with a fabulously rich "gold mine." And Babs, abducted by him, to be taken—where?
It set me shuddering.
"That's what it was," Alan reiterated. "And Polter, here now with what he calls a 'mine.' It isn't a mine, it's a laboratory! He's got father too, hidden God knows where! And now Babs. We've got to get them, George! The police can't help us! It's just you and me, to fight this thing. And it's diabolical!"
CHAPTER II.
We soared over the divided channel of the St. Lawrence, between Orleans and the mainland. Montmorency Falls in a moment showed dimly white through the murk to our left, a great hanging veil of ice higher than Niagara. Further ahead, the lights of the little village of St. Anne de Beaupré were visible with the gray-black towering hills behind them.
"Swing left, George. Over the mainland. That's St. Anne. We pass this side of it. Put the mufflers on. This damn thing roars like a tower siren."
I cut in the muffler and switched off our wing-lights. It was illegal but we were past all thought of that. We were both desperate; the slow prudent process of acting within the law had nothing to do with this affair. We both knew it.
Our little plane was dark, and amid the sounds of this night blizzard our muffled engine couldn't be heard.
Alan touched me. "There are his lights; see them?"
We had passed St. Anne. The hills lay ahead—a wild mountainous country stretching northward to the foot of Hudson Bay. The blizzard was roaring out of the North and we were heading into it. I saw, on what seemed like a dome-shaped hill perhaps a thousand feet above the river level, a small cluster of lights which marked Polter's property.
"Fly over it once, George," Alan said. "Low—we can chance it. And find a place to land near the walls."
We presently had it under us. I held the plane at five hundred feet, and cut our speed to the minimum of twenty miles an hour facing the gale,
