With his free arm Everett swept aside the vines, and, Monica following, they entered the tunnel. It was a pa.s.sageway cleanly cut through the solid rock and sufficiently wide to permit of their moving freely. At the farther end, at a distance of a hundred yards, it opened into a great vault, also hollowed from the rock and, as they saw to their surprise, brilliantly lighted.
For an instant, in black silhouette, the figure of Peabody blocked the entrance to this vault, and then, turning to the right, again vanished.
Monica felt an untimely desire to laugh. Now that they were on the track of Peabody she no longer feared the outcome of the adventure. In the presence of the American minister and of herself there would be no violence; and as they trailed the archaeologist through the tunnel she was reminded of Alice and her pursuit of the white rabbit. This thought, and her sense of relief that the danger was over, caused her to laugh aloud.
They had gained the farther end of the tunnel and the entrance to the vault, when at once her amus.e.m.e.nt turned to wonder. For the vault showed every evidence of use and of recent occupation. In brackets, and burning brightly, were lamps of modern make; on the stone floor stood a canvas cot, saddle-bags, camp-chairs, and in the centre of the vault a collapsible table. On this were bottles filled with chemicals, trays, and presses such as are used in developing photographs, and apparently hung there to dry, swinging from strings, the proofs of many negatives.
Loyal to her brother, Monica exclaimed indignantly. At the proofs she pointed an accusing finger.
"Look!" she whispered. "This is Peabody"s darkroom, where he develops the flash-lights he takes of the hieroglyphs! Chester has a right to be furious!"
Impulsively she would have pushed past Everett; but with an exclamation he sprang in front of her.
"No!" he commanded, "come away!"
He had fallen into a sudden panic. His tone spoke of some catastrophe, imminent and overwhelming. Monica followed the direction of his eyes.
They were staring in fear at the proofs.
The girl leaned forward; and now saw them clearly.
Each was a United States Treasury note for five hundred dollars.
Around the turn of the tunnel, approaching the vault apparently from another pa.s.sage, they heard hurrying footsteps; and then, close to them from the vault itself, the voice of Professor Peabody.
It was harsh, sharp, peremptory.
"Hands up!" it commanded. "Drop that gun!"
As though halted by a precipice, the footsteps fell into instant silence. There was a pause, and then the ring of steel upon the stone floor. There was another pause, and Monica heard the voice of her brother. Broken, as though with running, it still retained its level accent, its note of insolence.
"So," it said, "I have caught you?"
Monica struggled toward the lighted vault, but around her Everett threw his arm.
"Come away!" he begged.
Monica fought against the terror of something unknown. She could not understand. They had come only to prevent a meeting between her brother and Peabody; and now that they had met, Everett was endeavoring to escape.
It was incomprehensible.
And the money in the vault, the yellow bills hanging from a cobweb of strings; why should they terrify her; what did they threaten? Dully, and from a distance, Monica heard the voice of Peabody.
"No," he answered; "I have caught you! And I"ve had a h.e.l.l of a time doing it!"
Monica tried to call out, to a.s.sure her brother of her presence. But, as though in a nightmare, she could make no sound. Fingers of fear gripped at her throat. To struggle was no longer possible.
The voice of Peabody continued:
"Six months ago we traced these bills to New Orleans. So we guessed the plant was in Central America. We knew only one man who could make them. When I found you were in Amapala and they said you had struck "buried treasure"--the rest was easy."
Monica heard the voice of her brother answer with a laugh.
"Easy?" he mocked. "There"s no extradition. You can"t touch me.
You"re lucky if you get out of here alive. I"ve only to raise my voice--"
"And, I"ll kill you!"
This was danger Monica could understand.
Freed from the nightmare of doubt, with a cry she ran forward. She saw Peabody, his back against a wall, a levelled automatic in his hand; her brother at the entrance to a tunnel like the one from which she had just appeared. His arms were raised above his head. At his feet lay a revolver. For an instant, with disbelief, he stared at Monica, and then, as though a.s.sured that it was she, his eyes dilated. In them were fear and horror. So genuine was the agony in the face of the counterfeiter that Everett, who had followed, turned his own away. But the eyes of the brother and sister remained fixed upon each other, hers, appealingly; his, with despair. He tried to speak, but the words did not come. When he did break the silence his tone was singularly wistful, most tenderly kind.
"Did you hear?" he asked.
Monica slowly bowed her head. With the same note of gentleness her brother persisted:
"Did you understand?"
Between them stretched the cobweb of strings hung with yellow certificates; each calling for five hundred dollars, payable in gold.
Stirred by the night air from the open tunnels, they fluttered and flaunted.
Against the sight of them, Monica closed her eyes. Heavily, as though with a great physical effort, again she bowed her head.
The eyes of her brother searched about him wildly. They rested on the mouth of the tunnel.
With his lowered arm he pointed.
"Who is that?" he cried.
Instinctively the others turned.
It was for an instant. The instant sufficed.
Monica saw her brother throw himself upon the floor, felt herself flung aside as Everett and the detective leaped upon him; saw her brother press his hands against his heart, the two men dragging at his arms.
The cavelike room was shaken with a report, an acrid smoke a.s.sailed her nostrils. The men ceased struggling. Her brother lay still.
Monica sprang toward the body, but a black wave rose and submerged her.
As she fainted, to save herself she threw out her arms, and as she fell she dragged down with her the buried treasure of Cobre.
Stretched upon the stone floor beside her brother, she lay motionless.
Beneath her, and wrapped about and covering her, as the leaves covered the babes in the wood, was a vast cobweb of yellow bills, each for five hundred dollars, payable in gold.
A month later the harbor of Porto Cortez in Honduras was shaken with the roar of cannon. In comparison, the roaring of all the cannon of all the revolutions that that distressful country ever had known, were like fire-crackers under a barrel.
Faithful to his itinerary, the Secretary of State of the United States was paying his formal visit to Honduras, and the President of that republic, waiting upon the Fruit Company"s wharf to greet him, was receiving the salute of the American battle-ships. Back of him, on the wharf, his own barefooted artillerymen in their turn were saluting, excitedly and spasmodically, the distinguished visitor. As an honor he had at last learned to accept without putting a finger in each ear, the Secretary of State smiled with gracious calm. Less calm was the President of Honduras. He knew something the Secretary did not know.
He knew that at any moment a gun of his saluting battery might turn turtle, or blow into the harbor himself, his cabinet, and the larger part of his standing army.
Made fast to the wharf on the side opposite to the one at which the Secretary had landed was one of the Fruit Company"s steamers. She was on her way north, and Porto Cortez was a port of call. That her pa.s.sengers might not intrude upon the ceremonies, her side of the wharf was roped off and guarded by the standing army. But from her decks and from behind the ropes the pa.s.sengers, with a battery of cameras, were perpetuating the historic scene.
