Marlowe agreed faster than Briar expected — "For a genetics project," Briar had said, which by now felt like the lie she reached for out of habit — and let Briar swipe the inside of her cheek with a fresh swab in the back room of the flower shop, surrounded by buckets of chrysanthemums.

Briar had already sent in strands from her father's comb and three hairs from her mother's pillow, lifted at 2 a.m. while both parents slept down the hall.

The results came back nine days later, and Briar read them twice before she called Marlowe.

On the other end, Marlowe exhaled hard enough that it hissed through the phone speaker. "That's not a mix-up," she said slowly. "Mix-ups happen with two babies. This took somebody planning three."

Neither of them said Perpetua's name yet. But Briar's mind had already gone there, unbidden, to gray silk and a hand that had known exactly what was glowing on a phone screen before anyone told her.
