When I stepped onto the deck of the pool, it was just in time to see the splash, a bright plume reflected, along with a pair of sago palms, in the sliding glass doors of the clubhouse. It hung there for a moment, slowly released a handful of pearls, and then suddenly collapsed with a spatter against the water’s taut surface. An underwater ripple, a corrugated figure, slithered quickly away. When he hauled himself out of the water at the far end of the pool, he seemed to enlarge in the air like a bubble blown from a straw. Under a completely blank blue sky, not a thing beyond the immediate setting stirred. The pool shimmered; he stood toweling his hair. I had never seen him before.
