Nancy Tench

Nancy Tench is Bill's wife, holding down a quiet suburban household while her husband's work pulls him deeper into the minds of killers. She is warm, practical, and devoted to their marriage and their young son, wanting nothing more exotic than a stable, ordinary family life.

Stacey Roca plays the show's anchor to normalcy, the domestic counterweight to all that interview-room darkness, and she does it without ever seeming naive. As small cracks appear in her household, her steadiness becomes quietly unsettling rather than comforting — you watch her sensing something is wrong long before the plot confirms it.
