So, Phil had his way, and we set up a tiny blind in the upper valley to the west of the one I had made the sighting in. We spent several nights up in an oak tree, and saw a lot of Himalayan spotted deer, and some monkeys at dawn. Phil should have been pleased, but he only got sullen. It occurred to me from some of his mutterings that he had hoped all along to find the yeti; he had come craving that big discovery.

And one night it happened. The moon was gibbous, and thin clouds let most of its light through. About two hours before dawn I was in a doze, and Adrakian elbowed me. Wordlessly he pointed at the far side of a small pool in the stream.

Shadows in shadows, shifting. A streak of moonlight on the water—then, silhouetted above it, an upright figure. For a moment I saw its head clearly, a tall, oddly shaped, furry skull. It looked almost human.

I wanted to shout a warning; instead I shifted my weight on the platform. It creaked very slightly, and instantly the figure was gone.

“Idiot!” Phil whispered. In the moonlight he looked murderous. “I’m going after him!” He jumped out of the tree and pulled what I assumed was a tranquilizer pistol from his down jacket.

“You can’t find anything out there at night!” I whispered, but he was gone. I climbed down and took off after him—with what purpose I wasn’t sure.

Well, you know the forest at night. Not a chance of seeing animals, or of getting around very easily, either. I have to give it to Adrakian—he was fast, and quiet. I lost him immediately, and after that only heard an occasional snapped branch in the distance. More than an hour passed, and I was only wandering through the trees. The moon had set and the sky was about halfway to dawn light when I returned to the stream.

I rounded a big boulder that stood on the bank and almost ran straight into a yeti coming the other way, as if we were on a busy sidewalk and had veered the same direction to avoid each other.
