At intervals throughout the day Yasmini sent him food by silent messengers; so he ate, for "the thing to do," says Cocker, "is the first that comes to hand, and the thing not to do is worry." It is not easy to worry and eat heartily at one and the same time. Having eaten, he rolled up his sleeves and native-made cotton trousers and proceeded to clean the cave. After that he overhauled his stock of drugs and instruments, repacking them and making ready against opportunity.

"As I told that heathen with a gun out there, there's an end to everything!" he reflected. "May this come soon!"

When they changed the guard that afternoon he had grown weary of his own company and of fruitless speculation and was pacing up and down. The second guard proved even less communicative than the first, up to the point when, to lessen his ennui, King began to whistle. Because a Secret Service man must be consistent, the tune was not English, but a weird minor one to which the "Hills" have set their favorite love song (that is, all about hate in the concrete!).

The echo of the waterfall within the cave was like the roaring in a shell held to the ear, but each time he came near the entrance the new guard could catch a few bars of the tune. After a little while the hook-nosed ruffian began to sing the words to it, in a voice like a forgotten dog's.

So he stopped at the entrance and changed the tune. And the guard sang the words of the new tune, too. After that he came out into the light of day (direct sunlight was cut off by the huge height of the cliffs all around) and leaned in the entrance, smiling.

"Allah preserve thee, brother!" he remarked. "Thine is a voice like a warrior's—bold and big! Thou art a true son of the Prophet!"

"Aye!" said the fellow, "that I am! Allah preserve thee, for thou hast more need of it than I, although I guard thee just at present. Whistle me another one!"

So King whistled the refrain of a song that boasts of an Afghan invasion of India, and of the loot that came of it, and the prisoners, and the women—particularly the women, mentioning more than a few of them by name, and their charms in detail. It was a song to warm the very cockles of a Hillman's heart. Nothing could have been better chosen for that setting, of a cave mouth half-way down the side of a gash in earth's wildest mountains, with the blue sky resting on a jagged rim a mile above.

"Good!" said the bearded jailer. "Now begin again and I will sing!"
