I think this might be the scene after Anne Boleyn’s coronation, when Cromwell visits pregnant Anne in her bedchamber. The fragment from “Wolf Hall“:
“The bedcurtains are drawn close. He pulls them back. Anne is lying in her shift. She looks flat as a ghost, except for the shocking mound of her six-month child. In her ceremonial robes, her condition had hardly showed, and only that sacred instant, as she lay belly-down to stone, had connected him to her body, which now lies stretched out like a sacrifice: her breasts puffy beneath the linen, her swollen feet bare.”
One of my favourite scenes in the book. The dynamics between Anne & Cromwell is amazing.
