Lightning plays favorites, picking the one out of the many, singling certain people out of groups of hundreds, even thousands. Lightning plays pranks, and seems to enjoy them. Lightning reaches 50,000 degrees Fahrenheit, more than five times the heat of the sun. It can be a hundred miles long, as thin as a man’s pinkie. Its effects are puzzling and indiscriminate. There are trees that have been hit that show no effect and then, months later, suddenly wither. Doors are removed from their hinges; cars are set on fire, and afterward only the radio is found to be working, crooning a sad song. People safe in their houses, chatting on the phone, have had lightning come in through the wires, entering the earpiece to strike them deaf. In one case a dog that had been struck farted black sulfur for weeks. Hairpieces have been snatched off bald men’s heads, women have been stripped of their clothes, children have reported seeing flaming objects circling their rooms, only to be disbelieved until all the electricity goes out or the walls themselves catch fire.

Some people get up after a strike and finish their golf games, go about their business, have quite a story to tell. Others’ lives are forever ruined.

Is that magic? Does it make any sense? Most incidents of odd weather can be logically explained. Blood rains, once thought to be the wrath of the heavens, are actually made up of the mecondial fluids released by certain lepidoptera simultaneously emerging from their chrysalides. Black rains, those old wives’ tales, are in fact stones picked up in whirlwinds and released elsewhere. Frogs falling from the sky, same thing, no magic whatsoever; the poor creatures are simply swept up in one place by a windstorm, then deposited on the shores of another land. And what if these frogs open their mouths and pearls fall out? Even then logic prevails: the frogs have probably been air-lifted from the China Seas, home of pearls shining in a dozen different shades no one would never expect: red, scarlet, crimson. Pearls the color of a human heart.

At Orlon University, the team was working backward, trying to understand lightning by studying its effects on human physiology. Our group of survivors met in the cafeteria of the Science Center in the evenings. Summer school wasn’t yet in session; for now the campus was quiet. I didn’t believe in support groups; why should I go? Nothing could save me. All the same, my brother insisted the group was part of the study I had committed to. It was for the greater good, something I rarely considered. Ned called repeatedly to suggest that for once I finish something I’d started. He had a point, I suppose. But I had no desire to walk across the Orlon campus, however deserted it might be, with my hair falling out, still in need of a cane to steady my limp. I pronounced it imp, and it felt that way. An imp in my nervous system, pinching at this and that. Reminding me of who I was and who I’d never be.

I might have backed out at the last minute, unintentionally forgotten the time, the day, the location of the meeting, but Ned sent me a report he knew would intrigue me. It was a folder titled The Naked Man. How could I resist?

The Naked Man had been a roofer — a dangerous occupation, I knew from reading my safety tips. He was working after hours on his mother-in-law’s house on the occasion of his strike. He was forty-four years old, six foot two, 240 pounds. He was balding and wore a beard. He’d had two beers at the time of the incident, but he certainly wasn’t drunk. He worked alone. He’d never won the lottery, never owned a dog, never made a promise he hadn’t kept. Until recently.

That evening he was singing Johnny’s Cash’s “Ring of Fire.” Later, he realized this particular song was on his mind because he was having an affair with a woman who worked at the Smithfield Mall. Johnny Cash’s wife had written “Ring of Fire” when they fell in love and were married to other people. There was desire in that song, big-time. That was probably why the roofer was fixing his mother-in-law’s roof on such a dismal night. Guilt and desire, a bad combination. Storms were predicted, but he figured he had time. He figured a good deed might make up for his failings.

He was mistaken.

Halfway through his work, he heard a hissing sound, and he found himself thinking of hell and whether or not he might end up there, if such a place existed. His fingers started to tingle. And then he saw what he thought was the moon falling from the sky. But the moon had a tail, and that was surely a bad sign. It was ball lightning; it fell on the roof and rolled down toward him. It looked like a comet headed straight for him, a blue-black thing that was as solid and real as a truck or a boot or a living, breathing man. The roofer thought he might be face-to-face with the devil himself, that fallen angel. He thought about everything he hadn’t yet done in his life. All of a sudden owning a dog seemed like the most important thing in the world.
