We started back down. The steps seemed particularly slippery now, even though it might have been our jitters, and we walked slowly, using the blank slate of the right wall to keep our balance. The tower was silent, holding its breath, its heartbeat suddenly slow and far more distant than before, or perhaps I could only hear the blood rushing through my head.
Turning the corner, I saw the figure and shone my helmet light on it. If I’d hesitated a second longer, I never would have had the nerve. It was the body of the anthropologist, slumped against the left-hand wall, her hands in her lap, her head down as if in prayer, something green spilling out from her mouth. Her clothing seemed oddly fuzzy, indistinct. A faint golden glow arose from her body, almost imperceptible; I imagined the surveyor could not see it at all. In no scenario could I imagine the anthropologist alive. All I could think was, The psychologist lied to us, and suddenly the pressure of her presence far above, guarding the entrance, was pressing down on me in an intolerable way.
I put out a palm to the surveyor, indicating that she should stay where she was, behind me, and I stepped forward, light pointed down into the darkness. I walked past the body far enough to confirm the stairs below were empty, then hurried back up.
“Keep watch while I take a look at the body,” I said. I didn’t tell her I had sensed a faint, echoing suggestion of something much farther below, moving slowly.
“It is a body?” the surveyor said. Perhaps she had expected something far stranger. Perhaps she thought the figure was just sleeping.
“It’s the anthropologist,” I said, and saw that information register in the tensing of her shoulders. Without another word, she brushed past me to take up a position just beyond the body, assault rifle aimed into the darkness.
Gently, I knelt beside the anthropologist. There wasn’t much left of her face, and odd burn marks were all over the remaining skin. Spilling out from her broken jaw, which looked as though someone had wrenched it open in a single act of brutality, was a torrent of green ash that sat on her chest in a mound. Her hands, palms up in her lap, had no skin left on them, only a kind of gauzy filament and more burn marks. Her legs seemed fused together and half-melted, one boot missing and one flung against the wall. Strewn around the anthropologist were some of the same sample tubes I had brought with me. Her black box, crushed, lay several feet from her body.
“What happened to her?” the surveyor whispered. She kept taking quick, nervous glances back at me as she stood guard, almost as if whatever had happened wasn’t over. As if she expected the anthropologist to come back to horrifying life.
I didn’t answer her. All I could have said was I don’t know, a sentence that was becoming a kind of witness to our own ignorance or incompetence. Or both.
I shone my light on the wall above the anthropologist. For several feet, the script on the wall became erratic, leaping up and dipping down, before regaining its equilibrium.
… the shadows of the abyss are like the petals of a monstrous flower that shall blossom within the skull and expand the mind beyond what any man can bear …
“I think she interrupted the creator of the script on the wall,” I said.
“And it did that to her?” She was pleading with me to find some other explanation.
I didn’t have one, so I didn’t reply, just went back to observing as she stood there, watching me.
A biologist is not a detective, but I began to think like a detective. I surveyed the ground to all sides, identifying first my own boot prints on the steps and then the surveyor’s. We had obscured the original tracks, but you could still see traces. First of all, the thing—and no matter what the surveyor might hope, I could not think of it as human—had clearly turned in a frenzy. Instead of the smooth sliding tracks, the slime residue formed a kind of clockwise swirl, the marks of the “feet,” as I thought of them, elongated and narrowed by the sudden change. But on top of this swirl, I could also see boot prints. I retrieved the one boot, being careful to walk around the edges of the evidence of the encounter. The boot prints in the middle of the swirl were indeed from the anthropologist—and I could follow partial imprints back up the right-hand side of the wall, as if she had been hugging it.
An image began to form in my mind, of the anthropologist creeping down in the dark to observe the creator of the script. The glittering glass tubes strewn around her body made me think that she had hoped to take a sample. But how insane or oblivious! Such a risk, and the anthropologist had never struck me as impulsive or brave. I stood there for a moment, and then backtracked even farther up the stairs as I motioned to the surveyor, much to her distress, to hold her position. Perhaps if there had been something to shoot she would have been calmer, but we were left with only what lingered in our imaginations.
Another dozen steps up, right where you could still have a slit of a view of the dead anthropologist, I found two sets of boot prints, facing each other. One set belonged to the anthropologist. The other was neither mine nor the surveyor’s.
Something clicked into place, and I could see it all in my head. In the middle of the night, the psychologist had woken the anthropologist, put her under hypnosis, and together they had come to the tower and climbed down this far. At this point, the psychologist had given the anthropologist an order, under hypnosis, one that she probably knew was suicidal, and the anthropologist had walked right up to the thing that was writing the words on the wall and tried to take a sample—and died trying, probably in agony. The psychologist had then fled; certainly, as I walked back down I could find no trace of her boot prints below that point.
Was it pity or empathy that I felt for the anthropologist? Weak, trapped, with no choice.
The surveyor waited for me, anxious. “What did you find?”
“Another person was here with the anthropologist.” I told the surveyor my theory.
“But why would the psychologist do that?” she asked me. “We were going to all come down here in the morning anyway.”
I felt as if I were observing the surveyor from a thousand miles away.
“I have no idea,” I said, “but she has been hypnotizing all of us, and not just to give us peace of mind. Perhaps this expedition had a different purpose than what we were told.”
“Hypnotism.” She said the word like it was meaningless. “How do you know that? How could you possibly know that?” The surveyor seemed resentful—of me or of the theory, I couldn’t tell which. But I could understand why.
