There were times, a year ago, in Iceland, on a glacier, in the dark, in temperatures well below freezing, when Issa López thought to herself: “Who wrote this? What is wrong with this person?” López, the showrunner and director of Season 4 of the HBO anthology series “True Detective,” had only herself to blame.

This shivery “True Detective,” subtitled “Night Country,” premieres on Jan. 14. Set in Ennis, a fictional town in northwest Alaska, it stars Jodie Foster as the chief of police and Kali Reis as an intimidating state trooper. Opening just as the area descends into months of unrelieved darkness, the six-episode season has an icy milieu and a female gaze forcefully distinct from the show’s past outings.

Created by Nic Pizzolatto, “True Detective” debuted nearly a decade ago as a bayou noir starring Matthew McConaughey and Woody Harrelson. Sultry, macho and spanning two timelines set 17 years apart, it entwined a familiar serial killer investigation with sweaty philosophy and intimations of the supernatural. Though that first season had its critics, it made for essential, much debated viewing. The second season, set in an unglamorous Southern California exurb and starring Colin Farrell, Taylor Kitsch, Rachel McAdams and Vince Vaughn, made a smaller, grimmer splash, as did the third season, which starred Mahershala Ali and Stephen Dorff and relocated the action to the Ozarks.

That third season, which premiered in January 2019, attracted significantly fewer viewers. That might have meant the end of “True Detective.” But HBO believed the franchise could continue. The network began to search for a new showrunner for Season 4, preferably a woman of color. (Earlier seasons skewed overwhelmingly male and largely white, in front of the camera and behind it.) Among the potential candidates was López, a Mexican filmmaker who had written and directed a roster of Spanish-language features, including “Tigers Are Not Afraid,” a movie about missing and murdered women and children that mingled crime, fantasy and horror.

That film impressed Francesca Orsi, HBO’s head of drama. The essence of “True Detective,” Orsi said by phone in a recent interview, “is the way in which the horror genre is encapsulated within the detective noir narrative.” Confident that López could accomplish this, Orsi invited her to pitch a new season.
