There are great shows. Then there are lightning-in-a-bottle moments. For eight weeks in 2014, HBO’s True Detective Season 1 wasn’t just must-watch TV—it was a cultural possession.

Monaghan had the challenging role of the "detective’s wife," a trope often relegated to the background. However, she brought agency and fire to Maggie.
