The Mystery by Samuel Hopkins Adams (read e books online free txt) 📕

looked easiest the seas ran low. Ropes had been brought. After some dainty manoeuvring two of the sailors gained foothold and slung the ropes so that the remainder of the disembarcation was simple. Nor was the ascent of the cliff a harsh task. Half an hour after the landing the exploring party stood on the summit of the hill, where the black flag waved over a scene of utter desolation. The vegetation was withered to pallid rags: even the tiniest weedling in the rock crevices had been poisoned by the devastating blast.

In the midst of that deathly scene, the flag seemed instinct with a sinister liveliness. Whoever had set it there had accurately chosen the highest available point on that side of the island, the spot of all others where it would make good its signal to the eye of any chance farer upon those shipless seas. For the staff a ten-foot sapling, finely polished, served. A mound of rock-slabs supported it firmly. Upon the cloth itself was no design. It was of a dull black, the hue of soot. Captain Parkinson, standing a few yards off, viewed it with disfavour.

"Furl that flag," he ordered.

Congdon, the coxswain of the gig, stepped forward and began to work at the fastenings. Presently he turned a grinning face to the captain, who was scanning the landscape through his glass.

"Beggin' your pardon, sir," he said.

"Well, what is it?" demanded Captain Parkinson.

"Beggin' your pardon, sir, that ain't rightly no flag. That's what you might rightly call a garment, sir. It's an undershirt, beggin' your pardon."

"Black undershirt's a new one to me," muttered Trendon.

"No, sir. It ain't rightly black, look."

Wrenching the object from its fastenings, he flapped it violently. A cloud of sooty dust, beaten out, spread about his face. With a strangled cry the sailor cast the shirt from him and rolled in agony upon the ground.

"You fool!" cried Trendon. "Stand back, all of you."

Opening his medicine case, he bent over the racked sufferer. Presently the man sat up, pale and abashed.

"That's how poisonous volcanic gas is," said the surgeon to his commanding officer. "Only inhaled remnants of the dust, too."

"An ill outlook for the man we're seeking," the captain mused.

"Dead if he's anywhere on this highland," declared Trendon. "Let's look at his flag-pole."

He examined the staff. "Came from the beach," he pronounced. "Waterworn. H'm! Maybe he ain't so dead, either."

"I don't quite follow you, Dr. Trendon."

"Why, I guess our man has figured this thing all out. Brought this pole up from the beach to plant it here. Why? Because this was the best observation point. No good as a permanent residence, though. Planted his flag and went back."

"Why didn't we see him on the beach, then?"

"Did you notice a cave around to the north? Good refuge in case of fumes."

"It's worth trying," said the captain, putting up his glass.

"Hold on, sir. What's this? Here's something. Look here."

Trendon pointed to a small bit of wood rather neatly carved to the shape of an indicatory finger, and lashed to the staff, at the height of a man's face. The others clustered around.

"Oh, the devil!" cried Trendon. "It must have got twisted. It's pointing straight down."

"Strange performance," said the captain. "However, since it points that way--heave aside those rocks, men."

The first slab lifted brought to light a corner of cardboard. This, on closer examination, proved to be the cover of a book. The rocks rolled right and left, and as the flag-staff, deprived of its support, tottered and fell, the trove was dragged forth and handed to the captain. While the ground jarred with occasional tremors and the mountain puffed forth its vaporous threats, he and the surgeon, seated on a rock, gave themselves with complete absorption to the reading.

III THE CACHE

Outwardly the book accorded ill with its surroundings. In that place of desolation and death, it typified the petty neatness of office processes. Properly placed, it should have been found on a desk, with pens, rulers, and other paraphernalia forming exact angles or parallels to it. It was a quarto, bound in marbled paper, with black leather over the hinges. No external label suggested its ownership or uses, but through one corner, blackened and formidable in its contrast to the peaceful purposes of the volume, a hole had been bored. The agency of perforation was obvious. A bullet had made it.

"Seen something of life, I reckon," said Trendon, as the captain turned the volume about slowly in his hands.

"And of death," returned Captain Parkinson solemnly. "Do you know, Trendon, I almost dread to open this."

"Pshaw!" returned the other. "What is it to us?"

He threw the cover back. Neatly lettered on the inside, in the fine and slightly angular writing characteristic of the Teutonic scholar, was the legend:

Karl Augustus Schermerhorn, 1409-1/2 Spruce Street, Philadelphia, Pa.

With a strangled cry the sailor cast the shirt from him

The opposite page was blank. Captain Parkinson turned half a dozen leaves.

"German!" he cried, in a note of disappointment, "Can you read German script?"

"After a fashion," replied the other. "Let's see. Es wonnte sechs--und-- dreissig unterjacke," he read. "Why, blast it, was the man running a haberdashery? What have three dozen undershirts to do with this?"

"A memorandum for outfitting, probably," suggested the captain. "Try here."

"Chemical formulae," said Trendon. "Pages of 'em. The devil! Can't make a thing of it."

"Well, here's something in English."

"Good," said the other. "By combining the hyper-sulphate of iridium with the fumes arising from oxide of copper heated to 1000 C. and combining with picric acid in the proportions described in formula x 18, a reaction, the nature of which I have not fully determined, follows. This must be performed with extreme care owing to the unstable nature of the benzene compounds."

"Picric acid? Benzene compounds? Those are high explosives," said Captain Parkinson. "We should have Barnett go over this."

"Here's a name under the formula. Dr. A. Mardenter, Ann Arbor, Mich. That explains its being in English. Probably copied from a letter."

"This must have been one of the experiments in the valley that Slade told us of," said the captain, thoughtfully. "Why, see here," he cried, with something like exultation. "That's what Dr. Schermerhorn was doing here. He has the clue to some explosive so terrific that he goes far out of the world to experiment with its manufacture. For companions he chooses a gang of cutthroats that the world would never miss in case anything went wrong. Possibly it was some trial of the finished product that started the eruption, even. Do you see?"

"Don't explain enough," grunted Trendon. "Deserted ship. Billy Edwards. Mysterious lights. Slade and his story. Any explosives in those? Good enough, far as it goes. Don't go far enough."

"It certainly leaves gaps," admitted the other.

He turned over a few more pages.

"Formulas, formulas, formulas. What's this? Here are some marginal annotations."

"Unbehasslich," read Trendon. "Let's see. That means 'highly unsatisfactory,' or words to that effect. Hi! Here's where the old man loses his temper. Listen: 'May the devil take Carroll and Crum for careless'--h'm--well, 'pig-dogs.' Now, where do Carroll and Crum come in?"

"They're a firm of analytical chemists in Washington," said the captain. "When I was on the ordnance board I used to get their circulars."

"Fits in. What? More English? Worse than the German, this is."

The writing, beginning evenly enough at the top of a page, ran along for a line or two, then fell, sprawling in huge, ragged characters the full length. Trendon stumbled among them, indignantly.

"June 1, 1904," he read. "It is done. Triumph. (German word.) Eureka. Es ist gefillt. From the (can't make out that word) of the inspiration--god-like power--solution of the world-problems. Why, the old fool is crazy! And his writing is crazier. Can't make head or tail of it."

The captain turned several more pages. They were blank. "At any rate, it seems to be the end," he said.

"I should hope so," returned the other, disgustedly.

He took the book on his knees, fluttering the leaves between thumb and finger. Suddenly he checked, cast back, and threw the book wide open.

"Here beginneth a new chapter," said he, quietly.

No imaginable chirography could have struck the eye with more of contrast to the professor's small and nervous hand. Large, rounded, and rambling, it filled the page with few and careless words.

June 2, 1904. On this date I find myself sole occupant and absolute monarch of this valuable island. This morning I was a member of a community, interesting if not precisely peaceful. To-night I am the last leaf. 'All his lovely companions are faded and gone,' the sprightly Solomon, the psychic Nigger, the amiable Thrackles, the cheerful Perdosa, the genial Pulz, and the high-minded Eagen. Undoubtedly the social atmosphere has cleared; moreover, I am for the first time in my life a landed proprietor. Item: several square miles of grass land; item: several dozen head of sheep; item: a cove full of fish; item: a handsomely decorated cave; item: a sportive though somewhat unruly volcano. At times, it may be, I shall feel the lack of company. The seagulls alone are not distrustful of me. Undoubtedly the seagull is an estimable creature, but he leaves something to be desired in the way of companionship. Hence this diary, the inevitable refuge of the empty-minded. Materially, I shall do well enough, though I face one tragic circumstance. My cigarette material, I find, is short. Upon counting up--"

"Damn his cigarettes!" cried the surgeon. "This must be Darrow. Finicky beast! Let's see if it's signed."

He whirled the leaves over to the last sheet, glanced at it, and sprang to his feet. There, sprawled in tremulous characters, as by a hand shaken with agony or terror, was written:

Look for me in the cave. Percy Darrow.

The bullet hole in the corner furnished a sinister period to the signature.

Trendon handed the ledger back to the captain, who took one quick look, closed it, and handed it to Congdon.

"Wrap that up and carry it carefully," he said.

"Aye, aye, sir," said the coxswain, swathing it in his jacket and tucking it under his arm.

"Now to find that cave," said Captain Parkinson to the surgeon.

"The cave in the cliff, of course," said Trendon. "Noticed it coming in, you know."

"Where?"

"On the north shore, about a mile to the east of here."

"Then we'll cut directly across."

"Beg your pardon, sir," put in Congdon, "but I don't think we can make it from this side, sir."

"Why not?"

"No beach, sir, and the cliff's like the side of a ship. Looks to be deep water right into the cave's mouth."

"Back to the boat, then. Bring that flag along."

The descent was swift, at times reckless, but the party embarked without accident. Soon they were forging through the water at racing speed, the boat leaping to the impulsion of the sailorman's strongest motives, curiosity and the hope of saving a life.

IV THE TWIN SLABS

Within half an hour the gig had reached the mouth of the cave. As the coxswain had predicted, the seas ran into the lofty entrance. Elsewhere the surf fell whitely, but through the arch the waves rolled unbroken into a heavy stillness. Only as the boat hovered for a moment at the face of the cliff could the exploring party hear, far within, the hollow boom that told of breakers on a distant, subterranean beach.

"Run her in easy," came the captain's order. "Keep a sharp lookout for hidden rocks."

To the whispering plash of the oars they moved from sunlight into twilight, from twilight into darkness. Of a sudden the oars jerked convulsively. A great roar had broken upon the ears of the sailors; the invisible roof above them, the water heaving beneath them, the walls that hemmed them in, called, with a multiplication of resonance, upon the name of Darrow. The boat quivered with the start of its occupants. Then one or two laughed weakly as they realised that what they had heard was no supernatural voice. It was the captain hailing for the marooned man.

No vocal answer came. But
