Poderia ser "A Magia Menor"de Gregory Kusnick em análogo, Abril 1987. De acordo com "Revisão da fantasia"trata-se de um exame científico dos poderes de um psíquico.
Eles se apaixonam, se separam, anos depois se reencontram. Ela se tornou uma médium de sucesso, ele se tornou um desmascarador profissional.
Houston pivoted and strode upstage to his chair. "On my left is Thalia Sky, the well-known San Francisco psychic. On my right is Dr. Marc Bannard, writer, lecturer, Stanford University psychologist, and president of the California Society of Rationalists. Dr. Bannard, perhaps you could start by telling us just what your group stands for."

Marc flinched away from that gaze, still shocked at seeing her again. He'd heard of Thalia Sky, of course; what debunker hadn't? Yet until today he'd never met her, nor seen a picture of her—nor dreamt in his most fevered nightmares that sweet, shy Thea Welkin could grow up into such a creature.
Ele prova que ela não é psíquica ao descobrir que pode ver além do espectro visual e, assim, ler pistas que são invisíveis para todos os outros.
É o chefe de departamento de Marc, John Verrine, quem descobre isso.
"Aspergillus sudophilus," Verrine replied. "A species of skin fungus related, if I recall correctly, to the yeasts. It's quite widespread, though basically harmless; I suppose that's why it hasn't drawn a lot of attention. I had to search through quite a few journals to find a description of it."
[. . . .]
"It seems to be some kind of fluorescent effect," Verrine explained, "rather like a Day-Glo pigment. Lord knows what purpose it serves. Perhaps none, perhaps it's merely a side-effect of some routine biochemical activity. But apparently it's not at all uncommon for microbes of this general type to show some kind of fluorescence, at one wavelength or another. This one seems to absorb energy in the near ultraviolet, at about 3000 angstroms, and re-emit it rather broadly around 3500 angstroms—so close to the visible, in fact, that ordinary window glass is largely transparent to it. The exact spectrum—"

He gestured toward the incubator. "The temperature in the box right now is thirty-five degrees Celsius: typical human skin temperature. If I change the temperature—" He reached out and adjusted a knob; on the monitor the microbial glow became marginally greener. "—the spectrum of luminescence changes. We've also found it to be remarkably sensitive to changes in acidity, moisture, applied electric field, and a number of other factors. A kind of natural polygraph, if you will. The journal articles I found make no mention of that aspect of it. But then who'd think to look, eh?"
[. . . .]
Verrine turned to Marc, waved the folder in his face. "You see? Change just one DNA codon, one protein, one retinal pigment—and where we see blue, she sees ultraviolet. That portrait in your office was the key: all low-frequency colors, reds and greens and yellows. No blue in the picture at all, except for the facial aura—"
"Marc," Thea cut in. "Marc, what is it? What's he saying?"
"Just a minute!" Marc squeezed his eyes shut, pressed his hands to his temples. Ultraviolet vision? he thought wildly. Fluorescent skin fungi? It's crazy . . .
