I stared out at the cave mouth. Each moment it grew lighter. I thought that I should have liked to have seen one more summer dawn. But Helzephron was lifting his whistle; and then the mouth of the cave seemed to recede and shrink to the size of a mere window.

A mere window. With idle curiosity I saw how a fat spider was slowly descending his swinging thread, and I was a child again, seated at the nursery window....

The whistle blew a shrill, echoing blast.

At once my mind awoke to full consciousness, and I braced myself to die without a cry. The cave mouth became itself again, and the spider ...

_Hanging by one arm and a leg, half-way down a stout rope, was a short, thick-set figure...._

As the rapid thud of the racing dogs grew loud the figure"s right arm raised itself.

_Bang! Crash! Bang! Crash!_ a wild howl of pain, thunderous echoes rolling down the cavern, and Helzephron on his feet in time to see something bounding towards him like an india-rubber ball.

I knew who that was. I had one glimpse of a terrible grinning face as Danjuro leapt at the hawk-faced man; heard a strangled scream and a long, crunching crack, and saw two whirling figures crash to the floor.

I can"t express the suddenness of it all. Before my brain could register the impression, another person was sprinting by me, yelling like a fiend. Then Danjuro rose from the floor--alone--and my ropes were being divided, my stiff limbs rubbed, and a calm, exultant voice remarked: "Exit Honourable Helzephron."

I began to laugh weakly.

"You were just in time, Danjuro. Have you killed him?"

He was about to reply when there was a diversion.

Charles Thumbwood appeared. He had Mr. Vargus by the collar, and was kicking him along to the accompaniment of flowers of language that I shall not attempt to reproduce.

"Caught "im at the telephone," gasped Charles. "Gr-r-r, you little swine"--a furious kick--"Gr-r-r, you slime-lapping leper you! "E was telephoning to "is friends, Sir John. Thank Gawd we come in time, Sir John! Gr-r-r, there"s one as you won"t forget in an "urry!" and lifting Mr. Vargus several inches from the floor with a final kick, Little Thumbwood flung him away, began to feel me all over with trembling hands, and burst into a flood of tears.

But I had caught his words. The telephone! We should have all the band upon us in two minutes, desperate and fighting for their lives.

"Quick!" I shouted, "follow me. We must get Miss Shepherd safe. There isn"t a moment to lose."

I don"t know how I did it, and the first few yards were like running on red-hot ploughshares; but I got going, and raced down the great cave, past the Pirate Ship, to the door at the end.

I noticed a door on the left as I ran. It was the one by which I had first entered, the one that marked the pa.s.sage leading to the lift.

"Block that somehow!" I called to Thumbwood. "It may keep them back for a minute or two. Shoot anyone who breaks through."

He understood and stopped at once. I saw him dragging up some cases to make cover and lying down behind them, as I turned just outside the door which led to the ante-room to Helzephron"s private sanctum.

... We found Constance upon her knees in a richly furnished room. Her maid, Wilson, was weeping and trembling in a corner. As we burst in she shrieked with terror.

But Constance fainted dead away.

I took that unfortunate woman, Wilson, and shook her into sanity. There was nothing else to be done, and I remember that it seemed quite natural and obvious at the time. I knew that we hadn"t a moment to lose, and I was in a state of abnormal excitement.

When she had regained some sort of control, which was in less than a minute, I ordered her to attend to Constance, and, when she came to herself, to tell her that we were all saved and Helzephron as powerless.

Then I hurried out into the cave.

Danjuro and Thumbwood were working like demons. Piles of boxes and other impedimenta had been erected in two strategic positions commanding the door. Behind each pile were two or three automatic rifles and many clips of ammunition. Just as I came up Danjuro went to the door and opened it wide.

I grasped his idea at once. As you may remember from my former description, the pa.s.sage was a mere cleft in the rock. Certainly not more than one man could walk abreast, and he could be shot down the moment he turned the corner. A child who could shoot straight would have been able to hold the pa.s.sage, and behind the barrier on the floor of the cave would have been safe enough.

"I trust honourable lady quite safe?" said Danjuro in his quiet, silky voice.

"Yes; the maid"s attending to her. Thank G.o.d that unutterable scoundrel has not harmed her."

Then I remembered something. Danjuro"s face was perfectly placid and ordinary. The grinning devil-mask had vanished as if it had never been.

To look at him no one would have guessed that he was anything but a peaceable little Eastern student, such as you may see by the dozen any day round about the Law Courts in town. He rolled a cigarette in his conjuring way as I spoke, and yet, a few moments ago those slender hands had just broken the neck of the Master Criminal of Europe!

"Look here, old chap," I said. "I haven"t had a moment to thank you. You and Charles arrived in the very nick of time. A few seconds more and I should have been done for; and as for Miss Shepherd ..."

I couldn"t go on. I just held out my hand.

He didn"t take it--cold-blooded little beggar! He just bowed politely and murmured something that sounded like "Glad to be of any help!" Then he brightened up. "I think, Sir John," he said, "that we can reckon ourselves as quite safe from any intrusion now!" and he waved his hand towards the open door.

"Let "em all come!" remarked Thumbwood.

Then, quite suddenly, the floor of the cave seemed to heave up and down.

The great arc lights which made it as bright as day began to wheel round like fireworks, and I fainted for the second time.

When I recovered it was to find myself in the late Helzephron"s own room. Something cold was on my forehead and something chilly and scented trickled down my face. I opened my eyes, and Constance was kneeling by my side.

"My love, my dear love!" she whispered. "I never thought that I should see you alive again. Oh, thank G.o.d, thank G.o.d!"

Then her arms were round me, and for a long time we spoke no word. I think I know what the man who was called back from death in Palestine long ago must have felt....

She gave me food and wine, and at last, though I felt physically weak and shaken, my mind worked again, and I stood up. We were alone in the room, and no sound came from outside, so I concluded that all was safe for the present.

"A little j.a.panese carried you in here," Connie said, "as easily as if you were a child. I had just come to myself, and I thought, oh, John, I thought that you had been killed, and that he was one of those awful people. But he shouted out at once that what Wilson said was true and we were saved. I believed him, in spite of the shock his appearance gave me at first, and when he had put you down gently in this chair he hurried away. John, who is he, and how are we saved?"

"We owe everything to him," I answered gravely. "He killed Helzephron with his own hands"--I did not tell her about the dogs just then--"and in a few hours we shall be back in the world. We can never, as long as we live, pay our debt to Danjuro."

In as short a time as I could, I explained everything to her, from the first moment when I had heard of her capture until now. I walked about the room as I did so, and new life flowed into my cramped limbs. When I had smoked a cigarette, I felt almost normal again.

"Now, dear," I said, when my story was over, "we aren"t exactly out of the wood yet, though there"s nothing whatever to be alarmed at. Go into your own room and collect your things together; whatever you want to take away with you. Stay here with Wilson till I come again. I may be some time. There are a good many things to straighten out."

One more embrace and I left her, sobbing with great happiness, and, pa.s.sing through the ante-room, hurried out into the great cave.

My first glance was towards the door of the rock pa.s.sage leading to the lift. It was still open. Sitting on the barrier twelve yards or so away was Thumbwood. A rifle lay across his knees and he was placidly smoking his pipe.

"All right?" I shouted.

"All O.K., Sir John," he answered, standing up.

"Not a sign of anyone. As a matter of fact, Mr. Danjuro and me have ascertained that this "ere dog-fancier "adn"t time to get through to his friends upstairs. I got "old of "im just as he was topping the fence."

I followed his glance, and I saw Mr. Vargus, trussed like a fowl, on the floor a yard or two away.

I had quite forgotten that ingenious and artistic person, and I started.
