Old Money
Two Cribs, One Lie

Proof

Briar had taken a cup from the winter garden without thinking much about it — habit, muscle memory from cataloguing evidence for a week straight — the rim Perpetua had sipped tea from twice during their conversation, forgotten on the stone bench when Perpetua swept off toward the house.

She almost hadn't bothered sending it in. It felt insane, mailing an old woman's abandoned teacup to a lab like Briar was running her own private crime unit instead of finishing senior year. She did it anyway, the same paranoid instinct that had made her photograph both wristbands with her phone before Delphine's box vanished — every torn letter, every scratched-out word, backed up in a cloud folder Perpetua couldn't burn or steal.

The results came back on a Tuesday, while Briar was supposed to be in AP Statistics.

GRANDPARENT-GRANDCHILD RELATIONSHIP DETECTED. Probability: 99.6%.

She sat in the school parking lot and read it until the letters stopped making sense as words.

Perpetua Vantree was her grandmother.

Not a scheming nanny with a grudge. Not a stranger who'd wandered into a hospital hallway on a whim. Family — real, blood family, the only kind Briar had left once you subtracted the two people who'd raised her and the two people who'd raised Marlowe by mistake. Perpetua hadn't swapped Briar into the Keswick fortune out of simple cruelty toward Marlowe's parents. She'd done it to put her own bloodline, quietly, permanently, into a fortune she herself had been cut out of decades earlier.

Briar had spent eighteen years as the answer to Perpetua's oldest grievance, and never once known it.

She called Marlowe first, hands shaking too badly to type. She was still on the phone, still trying to explain the percentage through tears that had come out of nowhere, when Marlowe's uncle texted them both three words from his desk at the county clerk's office, where he'd been keeping half an eye on public filings all week the way only a man doing his niece a very large favor would.

VANTREE — EMERGENCY WILL MEETING — TODAY, 4 PM.

Perpetua wasn't waiting to be caught. She was already moving to make sure that when the truth came out, it wouldn't cost her anything at all.
