Fool's Gold

Mexico City

Chapter One — Density

The scale was a German model, ten years old, accurate to one ten-thousandth of a gram, and it had never lied to Renata Solís in nine years of service. She had cleaned it that morning with a goat-hair brush. She had let it warm for an hour. She had calibrated it twice against the brass reference weights that lived in their felt-lined case like a clutch of dull eggs. The scale was not the problem. She wanted very badly for the scale to be the problem.

She set the trophy's removable upper element onto the pan — only the upper element, the figure, unscrewed from its base with the brass tool the Federation's own conservation office had supplied decades ago — and she read the number, and then she stood very still in the cold white light of the lab and read it again.

Outside, somewhere across the city, ninety thousand people were already drinking. Tomorrow night the final would fill the great bowl of the stadium in the south, and the thing on her scale would be carried out under lights to be kissed by whichever captain lifted it, and four billion people would watch the gold catch fire on their screens. That was why the trophy was here, in a sealed room in the basement of the national museum's conservation annex, three days early. The Federation wanted it perfect. They wanted the small scuffs of a hundred celebrations buffed away, the patina evened, the whole object certified sound and authentic by an independent specialist whose signature meant something. They had chosen her because her signature meant something.

The number on the scale meant something too.

It was wrong by eleven grams.

Eleven grams was nothing. Eleven grams was a coin, a folded note, a swallow of water. On most objects in her care, eleven grams would be a rounding error, a smear of old wax, a difference in humidity between one week and the next. But this object had a documented mass. It had been weighed and recorded at every official handover for as long as there had been official handovers, and the figure had not moved in forty years, because solid gold does not lose weight. It does not evaporate. It does not breathe. Eleven grams of gold did not simply leave a sealed trophy between one ceremony and the next.

Unless the eleven grams had never been there.

Renata wrote the number in her notebook in pencil, in her small upright hand, the way she had been taught to record everything before she allowed herself to think about it. *Recorded mass minus measured mass: −11.2 g.* She underlined it once. Then she capped the pencil, because she had noticed that her fingers wanted to keep writing, to fill the page with the noise of her own alarm, and a conservator who lets her hands run is a conservator who makes mistakes.

She picked up the figure again. She had handled it a dozen times in the last three days and it had felt exactly as a thing of that size in solid gold should feel — dense, sullen, reluctant to be lifted, with that particular dead heaviness that gold alone has, heavier than it looks, heavier than the eye is ever ready for. That was the first thing they taught you about gold. The hand knows before the instruments do. The hand had not warned her. The hand had been satisfied.

But the hand could be fooled by the right alloy under the right plating, and the scale could not.

She did the arithmetic she did not want to do. The figure displaced a known volume; she had the museum's old measurements, water-displacement to four places, taken when the object last came in for cleaning six years ago. Mass over volume. She ran it twice on paper before she let herself read the result, and when she read it the result was a density that belonged to no version of gold that had ever existed. It was the density of something cheaper wearing gold's coat.

Renata sat down on the lab stool. The room was very quiet. The compressor of the climate unit cycled on with a soft thud and she heard her own pulse over it, which annoyed her, because she was a person who did not as a rule hear her own pulse.

The simplest explanation was that the museum's six-year-old volume figure was wrong. People made errors. Water-displacement of an irregular object was finicky; a bubble clinging to a fold of the cast could throw it off. She would do it again herself, tonight, properly, and the density would resolve into something honest and she would feel foolish and relieved in equal measure and she would go home and sleep.

That was the simplest explanation. She held onto it the way you hold a railing.

She looked at the figure in her gloved hands, the gold warm now from her skin, the surface throwing the lab's lights back at her in long soft streaks. It was beautiful. It had always been beautiful. A nation's children had grown up with its silhouette on bedroom walls and lottery tickets and the sides of buses. It was, in the most literal sense, priceless — not because of its gold, which would have bought a modest apartment, but because of what the gold had been made to mean.

If she was right, it was worth a great deal less than an apartment. It was worth whatever a clever forger had spent on base metal and a plating tank.

*Do the displacement again,* she told herself. *Stop building the cathedral before you've laid the stone.*

She filled the measuring vessel. She steadied her breath. She lowered the figure into the water and watched the meniscus climb, and she read it, and the water gave her exactly the same impossible answer the scale had given her, twice, with the patience of a thing that has nothing to hide.

The figure was not gold all the way through. The figure was barely gold at all.

She lifted it out and dried it with a soft cloth, automatically, tenderly, the way she dried everything, and she noticed that her hands had gone steady again, which was worse than the shaking would have been. Her hands had decided to believe her before the rest of her was ready.

Tomorrow night a captain would lift this into the air and weep, and the whole watching world would weep with him, and Renata Solís would be the only person on the planet who knew that what he was kissing was a lie.

She turned off the scale. She did not write anything else in the notebook. She sat in the cold white light and listened to the compressor cycle, on and off, on and off, and understood that her quiet, careful, unremarkable life had just ended, and that she did not yet know how.
