My vessel is at your disposal from peaks to bilges. Only I should like to know why all the vessels which happen to be in Pamlico Sound to-day are being subjected to this formality.”

“I see no reason why you should not be informed, Monsieur the Count,” replied the officer. “The governor of North Carolina has been apprised that Healthful House has been broken into and two persons kidnapped, and the authorities merely wish to satisfy themselves that the persons carried off have not been embarked during the night.”

“Is it possible?” exclaimed the Count, feigning surprise. “And who are the persons who have thus disappeared from Healthful House?”

“An inventor—a madman—and his keeper.”

“A madman, sir? Do you, may I ask, refer to the Frenchman, Thomas Roch?”

“The same.”

“The Thomas Roch whom I saw yesterday during my visit to the establishment—whom I questioned in presence of the director—who was seized with a violent paroxysm just as Captain Spade and I were leaving?”

The officer observed the stranger with the keenest attention, in an effort to surprise anything suspicious in his attitude or remarks.

“It is incredible!” added the Count, as though he had just heard about the outrage for the first time.

“I can easily understand, sir, how uneasy the authorities must be,” he went on, “in view of Thomas Roch’s personality, and I cannot but approve of the measures taken. I need hardly say that neither the French inventor nor his keeper is on board the Ebba. However, you can assure yourself of the fact by examining the schooner as minutely as you desire. Captain Spade, show these gentlemen over the vessel.”

Then saluting the lieutenant of the Falcon coldly, the Count d’Artigas sank into his deck-chair again and replaced his cigar between his lips, while the two officers and eight sailors, conducted by Captain Spade, began their search.

In the first place they descended the main hatchway to the after saloon—a luxuriously-appointed place, filled with art objects of great value, hung with rich tapestries and hangings, and wainscotted with costly woods.

It goes without saying that this and the adjoining cabins were searched with a care that could not have been surpassed by the most experienced detectives. Moreover, Captain Spade assisted them by every means in his power, obviously anxious that they should not preserve the slightest suspicion of the Ebba’s owner.

After the grand saloon and cabins, the elegant dining-saloon was visited. Then the cook’s galley, Captain Spade’s cabin, and the quarters of the crew in the forecastle were overhauled, but no sign of Thomas Roch or Gaydon was to be seen.

Next, every inch of the hold, etc., was examined, with the aid of a couple of lanterns. Water-kegs, wine, brandy, whisky and beer barrels, biscuit-boxes, in fact, all the provision boxes and everything the hold contained, including the stock of coal, was moved and probed, and even the bilges were scrutinized, but all in vain.

Evidently the suspicion that the Count d’Artigas had carried off the missing men was unfounded and unjust. Even a rat could not have escaped the notice of the vigilant searchers, leave alone two men.

When they returned on deck, however, the officers, as a matter of precaution looked into the boats hanging on the davits, and punched the lowered sails, with the same result.

It only remained for them, therefore, to take leave of the Count d’Artigas.

“You must pardon us for having disturbed you, Monsieur the Count,” said the lieutenant.

“You were compelled to obey your orders, gentlemen.”

“It was merely a formality, of course,” ventured the officer.

By a slight inclination of the head the Count signified that he was quite willing to accept this euphemism.

“I assure you, gentlemen, that I have had no hand in this kidnapping.”

“We can no longer believe so, Monsieur the Count, and will withdraw.”

“As you please. Is the Ebba now free to proceed?”

“Certainly.”

“Then au revoir, gentlemen, au revoir, for I am an habitué of this coast and shall soon be back again. I hope that ere my return you will have discovered the author of the outrage, and have Thomas Roch safely back in Healthful House. It is a consummation devoutly to be wished in the interest of the United States—I might even say of the whole world.”

The two officers courteously saluted the Count, who responded with a nod. Captain Spade accompanied them to the gangway, and they were soon making for the cruiser, which had steamed near to pick them up.

Meanwhile the breeze had freshened considerably, and when, at a sign from d’Artigas, Captain Spade set sail again, the Ebba skimmed swiftly through the inlet, and half an hour after was standing out to sea.

For an hour she continued steering east-northeast, and then, the wind, being merely a land breeze, dropped, and the schooner lay becalmed, her sails limp, and her flag drooping like a wet rag. It seemed that it would be impossible for the vessel to continue her voyage that night unless a breeze sprang up, and of this there was no sign.

Since the schooner had cleared the inlet Captain Spade had stood in the bows gazing into the water, now to port, now to starboard, as if on the lookout for something. Presently he shouted in a stentorian voice:

“Furl sail!”

The sailors rushed to their posts, and in an instant the sails came rattling down and were furled.

Was it Count d’Artigas’ intention to wait there till daybreak brought a breeze with it? Presumably, or the sails would have remained hoisted to catch the faintest puff.

A boat was lowered and Captain Spade jumped into it, accompanied by a sailor, who paddled it towards an object that was floating on the water a few yards away.

This object was a small buoy, similar to that which had floated on the bosom of the Neuse when the Ebba lay off Healthful House.

The buoy, with a towline affixed to it, was lifted into the boat that was then paddled to the bow of the Ella, from the deck of which another hawser was cast to the captain, who made it fast to the towline of the buoy. Having dropped the latter overboard again, the captain and the sailor returned to the ship and the boat was hoisted in.

Almost immediately the hawser tautened, and the Elba, though not a stitch of canvas had been set, sped off in an easterly direction at a speed that could not have been less than ten knots an hour.

Night was falling fast, and soon the rapidly receding lights along the American coast were lost in the mist on the horizon.

CHAPTER V.

WHERE AM I?

(Notes by Simon Hart, the Engineer.)

Where am I? What has happened since the sudden aggression of which I was the victim near the pavilion.

I had just quitted the doctor, and was about to mount the steps, close the door and resume my post beside Thomas Roch when several men sprang upon me and knocked me down. Who are they? My eyes having been bandaged I was unable to recognize them. I could not cry for help, having been gagged. I could make no resistance, for they had bound me hand and foot. Thus powerless, I felt myself lifted and carried about one hundred paces, then hoisted, then lowered, then laid down.

Where? Where?

And Thomas Roch, what has become of him? It must have been he rather than I they were after. I was but Gaydon, the warder. None suspected that I was Simon Hart, the engineer, nor could they have suspected my nationality. Why, therefore, should they have desired to kidnap a mere hospital attendant?

There can consequently be no doubt that the French inventor has been carried off; and if he was snatched from Healthful House it must have been in the hope of forcing his secret from him.

But I am reasoning on the supposition that Thomas Roch was carried off with me. Is it so? Yes—it must be—it is. I can entertain no doubt whatever about it. I have not fallen into the hands of malefactors whose only intention is robbery. They would not have acted in this way. After rendering it impossible for me to cry out, after having thrown me into a clump of bushes in the corner of the garden, after having kidnapped Thomas Roch they would not have shut me up—where I now am.

Where? This is the question which I have been asking myself for hours without being able to answer it.

However, one thing is certain, and that is that I have embarked upon an extraordinary adventure, that will end?—In what manner I know not—I dare not even imagine what the upshot of it will be.
