Self-Help
Once I’d started, I kept throwing up for several minutes. Every time my stomach contracted I couldn’t help doubling up and I’d vomit with my head underwater, then have to straighten up quickly to snatch a breath before the next heave. The vomiting finally stopped, although it took three dry retches before my stomach would concede it was empty. Then I was left, floating in blackness and amino acids, wondering what the fuck I should do next.
My first thought was that I should continue down the passage – I was assuming that I’d surfaced too soon, tricked by an air pocket left open by an extra-low tide. But that was easier said than done. While I’d been throwing up I’d twisted and turned twenty times, and was now completely disorientated. That led me to my second thought: I should work out the dimensions of the air pocket. This, at least, was something I could accomplish. Steeling myself, I reached up again and pushed my hand into the seaweed. I flinched, but this time I didn’t pull my hand back, and through the slimy growth I felt rock, an arm’s length above my head.
Several fumbling minutes later I’d created a good mental image of my surroundings. The pocket was about two metres wide and three metres long. On one side there was a narrow shelf, big enough to sit on, and everywhere else the walls curved straight down from the ceiling and ran into the water. There, the mental image began to fall apart. By groping around with my hands and feet, I seemed to find four passages leading into the rock, but it was hard to judge underwater. There could even have been more.
It was a grim discovery. If there’d been only two passages, then whichever direction I chose to swim, I’d either come up in the lagoon or the ocean. But these other passages could lead to nowhere. I could find myself swimming into a maze.
‘Two out of four,’ I heard myself muttering. ‘One in two. Fifty fifty.’ But it didn’t matter how I put it. The odds sounded bad.
The alternative was to stay put and hope Jed came to find me, but it wasn’t very appealing. I felt like I’d lose the plot if I waited in the pitch blackness, swimming around in my own sick, and I hadn’t the faintest idea how long it would be before I’d start breathing carbon dioxide. This was’ an idea I found particularly frightening. I could see myself huddled up on the small rock-shelf, gradually succumbing to a sinister sleepiness.
For a minute I stayed relatively still, treading water and going over my options. Then I started to panic. I splashed around wildly, bumping into the walls, choking, whimpering. I snatched at the seaweed above my head and pulled it down in great clumps. I lashed out, smashed my elbow on the rock-shelf, felt my skin tear and hot blood run over my arm. I shouted, ‘Help.’
‘Help.’
My voice sounded pathetic, like I was crying. It was a shocking noise and it jolted me into a second of silence. A second later, my fear was swamped by a sudden tidal wave of disgust. Ignoring the foul taste, I took a huge gulp of air and ducked underwater. I didn’t count the strokes this time, or worry about feeling my way. I took whichever of the four passages I found first and swam as hard as I could.
