Suddenly I reached out and s.n.a.t.c.hed the note from his hand. But before I could read it Del Mar had sprung to his feet.

At the same instant a man leaped out from behind the curtains.

But I was on my guard. Already I had drawn my revolver and had them all covered before they could make another move.

"Back into that corner--by the window--all of you," I ordered, thinking thus to get them together, more easily covered. Then, handing the note, with my other hand, to Elaine, I said to her, "See what it says--quick."

Eagerly she took it and read aloud, "House surrounded by soldiers."

"Woodward," I cried.

Still keeping them covered, I smiled quietly to myself and took one step after another slowly to the door. Elaine followed.

I reached the door and I remember that I had to step on a metal mat to do so. I put my hand behind me and grasped the k.n.o.b about to open the door.

As I did so, the man who had jumped from behind the curtain suddenly threw down his upraised hands. Before I could fire, instantaneously in fact, I felt a thrill as though a million needles had been thrust into all parts of my body at once paralyzing every muscle and nerve. The gun fell from my nerveless hand, clattering to the floor.

The man had thrown an electric switch which had completed a circuit from the metal mat to the door-k.n.o.b through my body and then to the light and power current of high power. There I was, held a prisoner, by the electric current!

At the same instant, also, Del Mar with an oath leaped forward and seized Elaine by the arms. I struggled with the door-k.n.o.b but I could no more let go than I could move my feet off that mat. It was torture.

"Henry!" called Del Mar to the valet.

"Yes, sir."

"Open the cabinet. Give me the helmets and the suits."

The valet did so, bringing out a number of queer looking head-pieces with a single weird eye of gla.s.s in the front, as well as rubber suits of an outlandish design. While he was doing so, Del Mar stuffed a handkerchief into Elaine's mouth to keep her quiet.

By this time, Del Mar, as well as the man from behind the curtains and the valet were provided with suits, and one at a time holding Elaine, the others put them on.

Del Mar moved toward Elaine, holding an extra helmet. He strapped it on her, then started to force her into a suit.

I struggled still, but in vain, to free myself from the door-k.n.o.b and mat. It was more than I could stand, and I sank down, half conscious.

I revived only long enough to see that Del Mar had forced one of the suits on Elaine finally. Then he pressed a b.u.t.ton hidden on the side of his desk and a secret panel in the wall opened. Picking up Elaine he and the others hurried through into what looked like a dark pa.s.sage and the panel closed.

They were gone. I put forth all my remaining strength in one last desperate struggle. Somehow, I managed to kick the wire mat from under my feet, breaking the contact.

I staggered toward the panel, but fell to the floor, unconscious.

Outside, the iron ring, as Woodward had planned it, of soldiers were looking about, alert for any noise or movement. Suddenly, two of them who had been watching the grounds attentively signalled to each other that they saw something.

From the shrubbery emerged a most curious and uncouth figure, all in rags, with long, unkempt hair and beard, sallow complexion, and carrying a long staff. It might have been a tramp or a hermit, perhaps, who was making his way toward the house.

The two soldiers stole up noiselessly, close to him. Almost before he knew it, the hermit felt himself seized from behind by four powerful arms. Escape was impossible.

"Let me go," he pleaded. "Can't you see I'm harming no one?"

But the captors were obdurate. "Tell it to the Lieutenant," they rejoined grimly forcing him to go before them by twisting his arms, "Our orders were to seize any one entering or leaving."

Protests were in vain. The hermit was forced to go before Lieutenant Woodward who was just in the rear directing the advance.

"Well," demanded Woodward, "what's your business?"

For an instant the hermit stood mute. What should he do? He has reason to know that the situation must be urgent.

Slowly he raised his beard so that Woodward could see not only that it was false but what his features looked like.

"Arnold!" gasped Woodward, startled. "What brings you here? Elaine and Jameson are in the house. We have it surrounded."

Half an hour before, in the St. Germain, Arnold had no sooner received the telaphotograph than he hurried up to his room. From a closet he had produced another of his numerous disguises and quickly put it on. With scant white locks falling over his shoulders and long scraggly beard, he had made himself into a veritable wild man. Then he had put on the finishing touches and had made his way toward Del Mar's.

A look of intense anxiety now flashed over Arnold's face as he heard Woodward's words.

"But," he cried, "there is an underground pa.s.sage from the house to the sh.o.r.e."

"The deuce!" muttered Woodward, more alarmed now than ever. "Come, men,--to the house," he shouted out his orders as they pa.s.sed them around the line. "Arnold, lead the way!"

Together the soldier and the strange figure rushed to the front door of the bungalow. All was still inside. Heavy as it was, they broke it down and burst in.

"Walter, there's Walter!" cried Woodward as he saw me lying on the floor of the study when they ran in.

They hurried to me and as quickly as they could started to bring me around.

"Where's Elaine?" asked the strange figure of the hermit.

Weakly, I was able only to point to the panel. But it was enough. The soldiers understood. They dashed for it, looking for a b.u.t.ton or an opening. Finding neither, they started to bang on it and batter it in with the b.u.t.ts of their guns.

It was only seconds before it was splintered to kindling. There was the pa.s.sage. Instantly, Woodward, the hermit, and the rest plunged into it utterly regardless of danger. On through the tunnel they went until at last they came, unmolested, to the end. There they paused to look about.

The hermit pointed to the ground. Clearly there were footprints, leading to the sh.o.r.e. They followed them on down to the beach.

"Look!" pointed the hermit.

Off in the water they could now see the most curious sights. Four strangely helmeted creatures were wading out, each like a huge octopus-head, without tentacles.

Only a few seconds before, Del Mar and his companions, carrying Elaine had emerged from the secret entrance of the tunnel and had dashed for the sh.o.r.e of the promontory.

Stopping only an instant to consider what was to be done, Del Mar had seen some one else emerge from the tunnel.

"Come--we must get down there quickly," he shouted, hurriedly issuing orders, as all three, carrying Elaine, waded out into the water.

At sight of the strange figures the soldiers raised their guns and a volley of shot rang out.

"Stop!" shouted the hermit, his hair streaming wildly as he ran before the guns and threw up as many as he could grasp with his outstretched arms. "Do you want to kill her?"
