Were they not afraid of me because I should be afraid of them? The question crossed my mind. But the answer—that they were harmless—was immediately apparent. To get close to a pond, around which they were densely packed, I had to nudge them away with my feet so as not to step on one. They took to my barging without any offence, making room for me like a good-natured crowd. I felt warm, furry bodies against my ankles as I looked into a pond.

All the ponds had the same round shape and were about the same size-roughly forty feet in diameter. I expected shallowness. I saw nothing but deep, clear water. The ponds seemed bottomless, in fact. And as far down as I could see, their sides consisted of green algae. Evidently the layer atop the island was very substantial.

I could see nothing that accounted for the meerkats’ fixed curiosity, and I might have given up on solving the mystery had squeaking and barking not erupted at a pond nearby. Meerkats were jumping up and down in a state of great ferment. Suddenly, by the hundreds, they began diving into the pond. There was much pushing and shoving as the meerkats behind vied to reach the pond’s edge. The frenzy was collective; even tiny meerkittens were making for the water, barely being held back by mothers and guardians. I stared in disbelief. These were not standard Kalahari Desert meerkats. Standard Kalahari Desert meerkats do not behave like frogs. These meerkats were most definitely a subspecies that had specialized in a fascinating and surprising way.

I made for the pond, bringing my feet down gingerly, in time to see meerkats swimming—actually swimming—and bringing to shore fish by the dozens, and not small fish either. Some were dorados that would have been unqualified feasts on the lifeboat. They dwarfed the meerkats. It was incomprehensible to me how meerkats could catch such fish.

It was as the meerkats were hauling the fish out of the pond, displaying real feats of teamwork, that I noticed something curious: every fish, without exception, was already dead. Freshly dead. The meerkats were bringing ashore dead fish they had not killed.

I kneeled by the pond, pushing aside several excited, wet meerkats. I touched the water. It was cooler than I’d expected. There was a current that was bringing colder water from below. I cupped a little water in my hand and brought it to my mouth. I took a sip.

It was fresh water. This explained how the fish had died—for, of course, place a saltwater fish in fresh water and it will quickly become bloated and die. But what were seafaring fish doing in a freshwater pond? How had they got there?

I went to another pond, making my way through the meerkats. It too was fresh. Another pond; the same. And again with a fourth pond.

They were all freshwater ponds. Where had such quantities of fresh water come from, I asked myself. The answer was obvious: from the algae. The algae naturally and continuously desalinated sea water, which was why its core was salty while its outer surface was wet with fresh water: it was oozing the fresh water out. I did not ask myself why the algae did this, or how, or where the salt went. My mind stopped asking such questions. I simply laughed and jumped into a pond. I found it hard to stay at the surface of the water; I was still very weak, and I had little fat on me to help me float. I held on to the edge of the pond. The effect of bathing in pure, clean, salt-free water was more than I can put into words. After such a long time at sea, my skin was like a hide and my hair was long, matted and as silky as a fly-catching strip. I felt even my soul had been corroded by salt. So, under the gaze of a thousand meerkats, I soaked, allowing fresh water to dissolve every salt crystal that had tainted me.

The meerkats looked away. They did it like one man, all of them turning in the same direction at exactly the same time. I pulled myself out to see what it was. It was Richard Parker. He confirmed what I had suspected, that these meerkats had gone for so many generations without predators that any notion of flight distance, of flight, of plain fear, had been genetically weeded out of them. He was moving through them, blazing a trail of murder and mayhem, devouring one meerkat after another, blood dripping from his mouth, and they, cheek to jowl with a tiger, were jumping up and down on the spot, as if crying, “My turn! My turn! My turn!” I would see this scene time and again. Nothing distracted the meerkats from their little lives of pond staring and algae nibbling. Whether Richard Parker skulked up in masterly tiger fashion before landing upon them in a thunder of roaring, or slouched by indifferently, it was all the same to them. They were not to be ruffled. Meekness ruled.

He killed beyond his need. He killed meerkats that he did not eat. In animals, the urge to kill is separate from the urge to eat. To go for so long without prey and suddenly to have so many—his pent-up hunting instinct was lashing out with a vengeance.

He was far away. There was no danger to me. At least for the moment.

The next morning, after he had gone, I cleaned the lifeboat. It needed it badly. I won’t describe what the accumulation of human and animal skeletons, mixed in with innumerable fish and turtle remains, looked like. The whole foul, disgusting mess went overboard. I didn’t dare step onto the floor of the boat for fear of leaving a tangible trace of my presence to Richard Parker, so the job had to be done with the gaff from the tarpaulin or from the side of the boat, standing in the water. What I could not clean up with the gaff—the smells and the smears—I rinsed with buckets of water.

That night he entered his new, clean den without comment. In his jaws were a number of dead meerkats, which he ate during the night.

I spent the following days eating and drinking and bathing and observing the meerkats and walking and running and resting and growing stronger. My running became smooth and unselfconscious, a source of euphoria. My skin healed. My pains and aches left me. Put simply, I returned to life.

I explored the island. I tried to walk around it but gave up. I estimate that it was about six or seven miles in diameter, which means a circumference of about twenty miles. What I saw seemed to indicate that the shore was unvarying in its features. The same blinding greenness throughout, the same ridge, the same incline from ridge to water, the same break in the monotony: a scraggly tree here and there. Exploring the shore revealed one extraordinary thing: the algae, and therefore the island itself, varied in height and density depending on the weather. On very hot days, the algae’s weave became tight and dense, and the island increased in height; the climb to the ridge became steeper and the ridge higher. It was not a quick process. Only a hot spell lasting several days triggered it. But it was unmistakable. I believe it had to do with water conservation, with exposing less of the algae’s surface to the sun’s rays.

The converse phenomenon—the loosening of the island—was faster, more dramatic, and the reasons for it more evident. At such times the ridge came down, and the continental shelf, so to speak, stretched out, and the algae along the shore became so slack that I tended to catch my feet in it. This loosening was brought on by overcast weather and, faster still, by heavy seas.

I lived through a major storm while on the island, and after the experience, I would have trusted staying on it during the worst hurricane. It was an awe-inspiring spectacle to sit in a tree and see giant waves charging the island, seemingly preparing to ride up the ridge and unleash bedlam and chaos—only to see each one melt away as if it had come upon quicksand. In this respect, the island was Gandhian: it resisted by not resisting. Every wave vanished into the island without a clash, with only a little frothing and foaming. A tremor shaking the ground and ripples wrinkling the surface of the ponds were the only indications that some great force was passing through. And pass through it did: in the lee of the island, considerably diminished, waves emerged and went on their way. It was the strangest sight, that, to see waves leaving a shoreline. The storm, and the resulting minor earthquakes, did not perturb the meerkats in the least. They went about their business as if the elements did not exist.
