Rewa Gunga laughed, resting his silk turban against the wall hangings and clasping both hands about his knee. It was as a man might laugh who has been touched in a bout with foils.

"Oh!-Ismail!" he called, with a voice like a bell, that made King stare.

The Afridi seemed to come out of a deep sleep and looked bewildered, rubbing his eyes and feeling whether his turban was on straight. He combed his beard with nervous fingers as he gazed about him and caught Rewa Gunga's eye. Then he sprang to his feet.

"Come!" ordered Rewa Gunga.

The man obeyed.

"Did you see?" Rewa Gunga chuckled. "He rose from his place like a buffalo, rump first and then shoulder after shoulder! Such men are safe! Such men have no guile beyond what will help them to obey! Such men think too slowly to invent deceit for its own sake!"

The Afridi came and towered above them, standing with gnarled hands knotted into clubs.

"What is thy name?" King asked him.

"Ismail!" he boomed.

"Thou art to be my servant?"

"Aye! So said she. I am her man. I obey!"

"When did she say so?" King asked him blandly, asking unexpected questions being half the art of Secret Service, although the other half is harder to achieve.

The Hillman stroked his great beard and stood considering the question. One could almost imagine the click of slow machinery revolving in his mind, although King entertained a shrewd suspicion that he was not so stupid as he chose to seem. His eyes were too hawk-bright to be a stupid man's.

"Before she went away," he answered at last.

"When did she go away?"

He thought again, then "Yesterday," he said.

"Why did you wait before you answered?"

The Afridi's eyes furtively sought Rewa Gunga's and found no aid there. Watching the Rangar less furtively, but even less obviously, King was aware that his eyes were nearly closed, as if they were not interested. The fingers that clasped his knee drummed on it indifferently, seeing which King allowed himself to smile.

"Never mind," he told Ismail. "It is no matter. It is ever well to think twice before speaking once, for thus mistakes die stillborn. Only the monkey-folk thrive on quick answers-is it not so? Thou art a man of many inches-of thew and sinew-Hey, but thou art a man! If the heart within those great ribs of thine is true as thine arms are strong I shall be fortunate to have thee for a servant!"

"Aye!" said the Afridi. "But what are words? She has said I am thy servant, and to hear her is to obey!"

"Then from now thou art my servant?"

"Nay, but from yesterday when she gave the order!"

"Good!" said King.

"Aye, good for thee! May Allah do more to me if I fail!"

"Then, take me a telegram!" said King.

He began to write at once on a half-sheet of paper that he tore from a letter he had in his pocket, setting down a row of figures at the top and transposing into cypher as he went along.

"Yasmini has gone North. Is there any reason at your end why I should not follow her at once?"

He addressed it in plain English to his friend the general at Peshawur, taking great care lest the Rangar read it through those sleepy, half-closed eyes of his. Then he tore the cypher from the top, struck a match and burned the strip of paper and handed the code telegram to Ismail, directing him carefully to a government office where the cypher signature would be recognized and the telegram given precedence.

Ismail stalked off with it, striding like Moses down from Sinai-hook-nose-hawk-eye-flowing beard-dignity and all, and King settled down to guard himself against the next attempt on his sovereign self-command.

Now he chose to notice the knife on the ebony table as if he had not seen it before. He got up and reached for it and brought it back, turning it over and over in his hand.

"A strange knife," he said.

"Yes,-from Khinjan," said Rewa Gunga, and King eyed him as one wolf eyes another.

"What makes you say it is from Khinjan?"

"She brought it from Khinjan Caves herself! There is another knife that matches it, but that is not here. That bracelet you now wear, sahib, is from Khinjan Caves too! She has the secret of the Caves!"

"I have heard that the 'Heart of the Hills' is there," King answered. "Is the 'Heart of the Hills' a treasure house?"

Rewa Gunga laughed.

"Ask her, sahib! Perhaps she will tell you! Perhaps she will let you see! Who knows? She is a woman of resource and unexpectedness-Let her women dance for you a while."

King nodded. Then he got up and laid the knife back on the little table. A minute or so later he noticed that at a sign from Rewa Gunga a woman left the great window place and spirited the knife away.

"May I have a sheet of paper?" he asked, for he knew that another fight for his self-command was due.

Rewa Gunga gave an order, and a maid brought him scented paper on a silver tray. He drew out his own fountain pen then and made ready.

In spite of the great silken punkah that swung rhythmically across the full breadth of the room the beat was so great that the pen slipped round and round between his fingers. Yet he contrived to write, and since his one object was to give his brain employment, he wrote down a list of the names he had memorized in the train on the journey from Peshawur, not thinking of a use for the list until he had finished. Then, though, a real use occurred to him.

While he began to write more than a dozen dancing women swept into the room from behind the silk hangings in a concerted movement that was all lithe slumberous grace. Wood-wind music called to them from the great deep window as snakes are summoned from their holes, and as cobras answer the charmer's call the women glided to the center and stood poised beneath the punkah.

There they began to chant, still dreamily, and with the chant the dance began, in and out, round and round, lazily, ever so lazily, wreathed in buoyant gossamer that was scarcely more solid than the sandalwood smoke they wafted into rings.

King watched them and listened to their chant until he began to recognize the strain on the eye-muscles that precedes the mesmeric spell. Then he wrote and read what he had written and wrote again. And after that, for the sake of mental exercise, he switched his thoughts into another channel altogether. He reverted to Delhi railway station.

"The Turks can spy as well as anybody.-They know those men are going to Kerachi to be ready for them.-Therefore, having cut his eye-teeth B.C. several hundred, the Unspeakable Turk will take care not to misbehave UNTIL he's ready. And I suppose our government, being ours and we being us, will let him do it! All of which will take time.-And that again means no trouble in the Hills-probably-until the Turks really do feel ready to begin. They'll preach a holy war just ahead of the date. The tribes will keep quiet because an army at Kerachi might be meant for their benefit. Oh, yes, I'm quite sure they were entraining for Kerachi in readiness to move on Basra.

"Trucks ready for camels-and camel drivers-and food for camels-and Eresby, who's just come from taking a special camel course. Not a doubt of it!-And then, Corrigan-Elwright-Doby-Gould-all on the platform in a bunch, and all down on the Army List as Turkish interpreters! Not a doubt left!"

"What have you written?" asked a quiet voice at his ear; and he turned to look straight in the eyes of Rewa Gunga, who had leaned forward to read over his shoulder. Just for one second he hovered on the brink of quick defeat. Having escaped the Scylla of the dancing women, Charybdis waited for him in the shape of eyes that were pools of hot mystery. It was the sound of his own voice that brought him back to the world again and saved his will for him unbound.

"Read it, won't you?" he laughed. "If you know, take this pen and mark the names of whichever of those men are still in Delhi."

Rewa Gunga took pen and paper and set a mark against some thirty of the names, for King had a manner that disarmed refusal.

"Where are the others?" he asked him, after a glance at it.
