Then I remembered Clatclit's manner of instruction to that hay-bale beast, what seemed like ages ago, out on the craggy Martian hillside. I put hooked thumb and forefinger into my mouth, and let off a piercing whistle.
Ahead of me in the darkness there was a glimmering of visibility, and then a feeble pink taillight waggled slowly up and down, far back beyond the other end of the bridge. Clatclit wasn't chancing moving as close to the death-dealing spray as before.
However, though a more powerful beam had been necessary to see by when I'd been moving into darkness, the pale glow was sufficient for the return trip. All I needed was a beacon, something to sight upon, so I wouldn't go astray in my slow crawl across that slippery curve of rock. Yes, crawl. This trip, I negotiated the arch on hands and knees.
And then I was across and hurrying down the corridor to the bend around which Clatclit shivered and waited. He stood up from his slouch against the wall, from which weary stance he'd been waving me onward with his taillight.
"Wow!" I said, catching dim sight of him in the weak glow of his water-pitted trylon. The sharp ruby glint was missing from his erstwhile pyramidic facets; now they looked dull crimson, and ropy, like taffy that has congealed after boiling over and dribbling down the side of the saucepan. "Does it hurt?" I asked, feeling partially responsible.
Side-to-side motion.
"It bothers you in some way, though, is that it?"
Nod.
"How?" I asked, unable to think of a yes-no question.
Clatclit pointed to my wrist, shook his head, pointed to my wrist again, and gestured upward, then nodded.
