Sally Mayberry

Sally Mayberry moves through the tense, moneyed world of The Undoing as one of the figures orbiting the central scandal—watchful, composed, and never quite giving away how much she knows. She speaks carefully, reads rooms instantly, and seems to understand the story's undercurrents before anyone says them aloud.

Janel Moloney brings the same coiled attentiveness she's known for to a role built on restraint, letting small shifts in expression carry more than dialogue does. In a series obsessed with what people conceal, she's convincing as someone who has learned to give nothing away for free.
