The Obsession

The coffee had gone cold again.

Ada Morrison stared at the cup on her desk—her fourth of the night, barely touched—and couldn’t remember when she’d poured it. An hour ago? Two? Time had that elastic quality when she was deep in research, stretching and compressing until the numbers on her computer screen mattered more than the clock on the wall.

2:47 AM.

She should go home. Everett would be asleep by now, sprawled across their bed in that way he did when she wasn’t there to complain about it. He’d texted her around midnight—just a heart, because after seven years he knew better than to ask when she’d be home. He understood the signs. The obsessive focus. The way she’d come straight from teaching to this office without stopping for dinner. The way her hand would drift to the pendant at her throat while she stared at nothing, thinking.

Her hand was there now. She hadn’t noticed it move.

The heirloom. Her grandmother’s, carved from some stone Ada had never been able to name despite sending shavings to half a dozen laboratories. She’d worn it since she was twelve—Nan had fastened it around her neck herself one ordinary afternoon, the clasp cold in the old woman’s fingers, the stone already warm against Ada’s skin. It had been warm ever since. Always warm, even when logic insisted it should be cool metal and inert crystal.

The symbols cut into its face caught the lamplight. She’d traced them ten thousand times, knew every curve and angle, had run them against every writing system she could find—Polynesian petroglyphs, Easter Island rongorongo, scripts dead three thousand years. Nothing matched. Nothing came close.

“What are you?” she murmured, turning it between her fingers.
