Denvil flushed hotly through his tan.

"I should be rather a poor sort of chap if I didn't manage to do pretty well—under you," he said, with awkward bluntness, looking straight between his charger's ears.

Desmond laughed. "Very neatly turned off, old chap. Now, I'm bound to call a halt till the Sikhs come up with us. Hope to goodness they'll be quick about it. Confounded nuisance having to wait."

Both men reined in their horses, and their consuming impatience. The squadron followed suit; and in an amazingly short time the Sikhs came into view, toiling lustily up the incline at their utmost speed.

Desmond turned in his saddle and raked the hillsides with his field-glasses.

"Looks empty enough, in all conscience," he remarked.

The words were hardly spoken when a single shot startled the echoes of the rocks, and instant alertness passed like an electric current through the squadron. The advance guard, which had already entered the defile, consisted of three promising young Pathans from Denvil's troop; and anxiety for the fate of his favourites pricked the Boy to keener impatience.

"I say, Desmond," he urged, "can't I take twenty men and push on to find out what's up. They'll be taking pot-shots at my men, unless I put a stop to it. For God's sake, let me go."

Desmond could not repress an approving smile at an impetuosity that matched his own. He glanced down the valley at the advancing Sikhs, and saw that he would not be long delayed in following on. Moreover, he shared the Boy's anxiety for his three picked men; and a shot fired, being tantamount to a declaration of hostilities, justified immediate advance to the scene of action.
