He silenced her questioning with a pa.s.sionate kiss. He carried her to a little nook and fumbled among the stores until he found a bottle of brandy. She drank some. Under its revivifying influence she was soon able to listen to the explanation he offered--after securing the ladder.

In a tall tree near the Valley of Death he had tightly fixed a loaded rifle which pointed at a loose stone in the rock overhanging the ledge held by the Dyaks. This stone rested against a number of percussion caps extracted from cartridges, and these were in direct communication with a train of powder leading to a blasting charge placed at the end of a twenty-four inch hole drilled with a crowbar. The impact of the bullet against the stone could not fail to explode some of the caps. He had used the contents of three hundred cartridges to secure a sufficiency of powder, and the bullets were all crammed into the orifice, being tamped with clay and wet sand. The rifle was fired by means of the string, the loose coils of which were secreted at the foot of the poon. By springing this novel mine he had effectually removed every Dyak from the ledge, over which its contents would spread like a fan. Further, it would probably deter the survivors from again venturing near that fatal spot.

Iris listened, only half comprehending. Her mind was filled with one thought to the exclusion of all others. Robert had left her, had done this thing without telling her. She forgave him, knowing he acted for the best, but he must never, never deceive her again in such a manner.

She could not bear it.

What better excuse could man desire for caressing her, yea, even squeezing her, until the sobs ceased and she protested with a weak little laugh----

"Robert, I haven't got much breath--after that excitement--but please--leave me--the remains!"

CHAPTER XIV

THE UNEXPECTED HAPPENS

"You are a dear unreasonable little girl," he said. "Have you breath enough to tell me why you came down the ladder?"

"When I discovered you were gone, I became wild with fright. Don't you see, I imagined you were wounded and had fallen from the ledge. What else could I do but follow, either to help you, or, if that were not possible--"

He found her hand and pressed it to his lips.

"I humbly crave your pardon," he said. "That explanation is more than ample. It was I who behaved unreasonably. Of course I should have warned you. Yet, sweetheart, I ran no risk. The real danger pa.s.sed a week ago."

"How can that be?"

"I might have been blown to pieces whilst adjusting the heavy stone in front of the caps. I a.s.sure you I was glad to leave the place that day with a whole skin. If the stone had wobbled, or slipped, well--it was a case of determined _felo-de-se_."

"May I ask how many more wild adventures you undertook without my knowledge?"

"One other, of great magnitude. I fell in love with you."

"Nonsense!" she retorted. "I knew that long before you admitted it to yourself."

"Date, please?"

"Well, to begin at the very beginning, you thought I was nice on board the _Sirdar_. Now, didn't you?"

And they were safely embarked on a conversation of no interest to any other person in the wide world, but which provided them with the most delightful topic imaginable.

Thus the time sped until the rising moon silhouetted the cliff on the white carpet of coral-strewn sand. The black shadow-line traveled slowly closer to the base of the cliff, and Jenks, guided also by the stars, told Iris that midnight was at hand.

They knelt on the parapet of the ledge, alert to catch any unusual sound, and watching for any indication of human movement. But Rainbow Island was now still as the grave. The wounded Dyaks had seemingly been removed from hut and beach; the dead lay where they had fallen. The sea sang a lullaby to the reef, and the fresh breeze whispered among the palm fronds--that was all.

"Perhaps they have gone!" murmured Iris.

The sailor put his arm round her neck and gently pressed her lips together. Anything would serve as an excuse for that sort of thing, but he really did want absolute silence at that moment. If the Mussulman kept his compact, the hour was at hand.

An unlooked-for intruder disturbed the quietude of the scene. Their old acquaintance, the singing beetle, chortled his loud way across the park. Iris was dying--as women say--to remind Jenks of their first meeting with that blatant insect, but further talk was impossible; there was too much at stake--water they must have.

Then the light hiss of a snake rose to them from the depths. That is a sound never forgotten when once heard. It is like unto no other.

Indeed, the term "hiss" is a misnomer for the quick sibilant expulsion of the breath by an alarmed or angered serpent.

Iris paid no heed to it, but Jenks, who knew there was not a reptile of the snake variety on the island, leaned over the ledge and emitted a tolerably good imitation. The native was beneath. Probably the flight of the beetle had helped his noiseless approach.

"Sahib!"

The girl started at the unexpected call from the depths.

"Yes," said Jenks quietly.

"A rope, sahib."

The sailor lowered a rope. Something was tied to it beneath. The Mahommedan apparently had little fear of being detected.

"Pull, sahib."

"Usually it is the sahib who says 'pull,' but circ.u.mstances alter cases," communed Jenks. He hauled steadily at a heavy weight--a goatskin filled with cold water. He emptied the hot and sour wine out of the tin cup, and was about to hand the thrice-welcome draught to Iris when a suspicious thought caused him to withhold it.

"Let me taste first," he said.

The Indian might have betrayed them to the Dyaks. More unlikely things had happened. What if the water were poisoned or drugged?

He placed the tin to his lips. The liquid was musty, having been in the skin nearly two days. Otherwise it seemed to be all right. With a sigh of profound relief he gave Iris the cup, and smiled at the most unladylike haste with which she emptied it.

"Drink yourself, and give me some more," she said.

"No more for you at present, madam. In a few minutes, yes."

"Oh, why not now?"

"Do not fret, dear one. You can have all you want in a little while.

But to drink much now would make you very ill."

Iris waited until he could speak again.

"Why did you----" she began.

But he bent over the parapet--

"_Koi hai_!"[Footnote: Equivalent to "h.e.l.lo, there!"]

"Sahib!"

"You have not been followed?"
