The next morning, Mrs. Sterling appeared at Elena’s small apartment. She held a single, gritty, imperfect pearl—one of the few she’d recovered.

That night, at the gala for the city’s most prestigious historical society, Elena wore them. She was surrounded by women wearing "investment pieces"—South Sea pearls that glowed with a deep, internal luster and felt heavy against their silk gowns.

The cheap beads bounced loudly on the marble, their light weight making a distinct, hollow clack that the heavy, organic real pearls couldn't mimic. In the dark, the guests used the sound of the bouncing fakes as a trail to find their way toward the emergency exits.

Later that evening, the lights flickered and died. A transformer had blown three blocks away, plunging the marble hall into pitch blackness. In the scramble for phone flashlights, a frantic cry went up. Mrs. Sterling had tripped, and the silk thread of her $20,000 heirloom had snagged on a stray nail.

"Those are lovely, Elena," purred Mrs. Sterling, whose own necklace likely cost more than Elena’s car. Mrs. Sterling reached out, her eyes narrowing as she inspected the "luster." "They’re so... uniform."

A dozen "real" pearls—heavy, irregular, and priceless—clattered across the floor, vanishing into the shadows.

"Don't move!" Elena called out. She began tossing her fake pearls toward the sound of Mrs. Sterling’s gasping. "Follow the sound of the plastic!"
