In that instant I became a caretaker. I tended my clutch with single-minded devotion. I ﬂew endlessly around my eggs, fanning them with my dorsal ﬁns to enhance the ﬂow of nutrients. I chased off sundry predators, my fears now utterly subjugated to the hormonal imperatives of my caretaker role . . I was happy. Then – tragedy struck. I still cannot understand it.

And that was my undoing. My conﬁdence, I thought, was secure; somewhere in the distant heights was the rocky roof of the universe, and I would accept no lesser goal.
