Zero Percent
The marquee lights on the Keswick lawn made Briar's champagne glass look like it was full of gold. Her eighteenth birthday. Three hundred guests. A string quartet murdering a pop song into something her mother could dance to.
She'd almost forgotten about the DNA kit. Ninth-grade genetics teacher had assigned it two weeks ago — "compare your results with a parent, present hereditary traits Monday" — and she'd swabbed her cheek in the school bathroom like it was nothing.
The email landed at 9:47 p.m., right between the toast and the cake.
She opened it under the table, glass in one hand, phone in the other.
ANCESTRY MATCH: Anders Keswick — 0% shared DNA.
ANCESTRY MATCH: Rosalind Keswick — 0% shared DNA.
She read it four times. Lab error, she told herself. Contaminated sample. She'd redo it Monday.
"You look like you've seen a ghost," said a voice behind her, dry as a page turning.
Perpetua Vantree stood there in her usual gray silk, the woman who'd rocked Briar to sleep before Briar could walk, who still came for Sunday dinner though she hadn't worked for the family in a decade. Briar had never once thought to ask why an ex-nanny still had a standing invitation to Christmas.
"Just tired," Briar said, thumb sliding to lock the screen.
Perpetua's eyes dropped to the phone anyway — too fast, too precise, like she already knew exactly what was glowing on it.
"Some tests lie, sweetheart," Perpetua said softly, and reached out to smooth a strand of hair off Briar's shoulder, the way she'd done since Briar was small. "Best not to trust every stranger with a lab coat."
Briar forced a smile. "It's probably nothing."
"Of course it is." Perpetua's hand lingered a second too long at the back of Briar's neck before she turned, unhurried, toward the bar. "Happy birthday, darling."
Briar watched her go, champagne suddenly sour in her throat.
How had Perpetua known there was a test at all?
