I started up once more.

And then I heard it--a shrill blast of sound in an octave of urgency; a

whistle, sure, but a warning one.

I stopped in my tracks from the shock of it. Yes, I knew from whom it

had come, all right. But I didn't know why.

And then the whistle broke off short. One instant it was in the air,

shrieking with a message. The next it was gone. But it left tailings,

like the echo of a death cry slowly floating back over the dead body of

the creature that uttered it.

I dropped behind a fragment of the rag-cliff. A shot barked out

angrily. Splinters of the rock crazed the morning air.

The little boy screamed. Just once.

I waited. There was a long silence after that. Then, finally, I took

off my hat and threw it out into the valley. The gun roared once more.

This time I placed it a little to the left below me. I took careful

sighting on the hand that held that gun--and I didn't miss it.

It was Harry Smythe, of course. When I reached him, he had the injured

hand tucked tightly in the pit of his other arm. There was a grim look

in his eyes and he nodded as I approached him.

"Good shooting, mate. Should be a promotion in it for you. Shooting

like that, I mean."

"That's nice to think about," I said. "Where's the boy? I owe him a

little something. If he hadn't whistled a warning, you could have

picked me off neat."

"I would." He nodded calmly.

"Where is he?"

"Behind the rock there. In that little alcove, sort of." He indicated

with his chin.
