Shows about hunting diabolical killers and serial killers is not a new concept, but what makes A&E’s chilling drama THOSE WHO KILL stand out is the fact that its two leads seem close to becoming killers as much the criminals they pursue. THOSE WHO KILL stars Chloe Sevigny and James D’Arcy, who portray a homicide detective and a forensic psychologist respectively, and the real dance of the show is between Detective Catherine Jensen and Dr. Thomas Schaeffer, who seamlessly slip in to the minds of various killers. Such an ability foreshadows that they may pose their own danger to others, as well as each other. Just how far will they go to close a case, catch a killer, or even to get inside a killer’s mind? Rather than be repulsed by the crimes they become involved with, both seem entranced — like they are seeing another piece to a puzzle that only they can see.
Coming from damaged, dark pasts of their own, Catherine and Thomas present a unique crime-fighting pair. They are relentless and uncontrollably drawn to the killers they track.
At last week’s special premiere event for THOSE THAT KILL, stars Chloe Segivny and James D’Arcy along with their co-stars Kerry O’Malley, Bruce Davison, and Ryan O’Nan took a few minutes to talk about their characters:
As Chloe mentioned, what she appreciate mosts about her character Detective Catherine Jensen is how bold she is and the choices she makes. Catherine does not take any nonsense from anyone and she’s outside the box. In addition, she is driven. Like how she singled out Thomas Schaeffer. Catherine knows that if she is going to catch her diabolical stepfather, she is going to need someone like Schaeffer; and she must avenge her brother or she will never find peace in her own life — so she will use any means necessary to bring him to justice. Addressing the tenuous, distrustful level of their relationship, Chloe admits that Catherine and Schaeffer are both a bit damaged and they flirt with danger in ways they shouldn’t.
From his own perspective, co-star James D’Arcy admitted that the Catherine and Schaeffer relationship is tenuous because they cannot really trust each other. There is manipulation on both sides. Incongruously, Thomas simultaneously feels protective of Catherine and yet because Thomas studies people who are damaged, Thomas considers Catherine to be a live case to study. She is just so compelling that he is unable to stay away from her. But it is not all about just studying Catherine, as Thomas has a few secrets of his own and everything slowly starts to unravel for both of them as the season goes on. Secrets and personal agendas are not healthy and will lead to more problems.
Also providing a few insights was co-star Christopher Michael Holley, who portrays Lt. Mike Dunn, Catherine’s boss, who admitted that it is tricky for Dunn to be Catherine’s boss. She has a mind of her own and does not necessarily respect authority. Yet Dunn has respect for Catherine’s talent on the job. He also appreciates her tenacity.
Likewise, co-star Kerry OMalley who portrays forensic pathologist Mia Vogel and Catherine’s best friend, said that Mia senses that Catherine is in crisis and in a lot of pain. Mia does her best to support her and keep Catherine on the right path, since she knows how easy it is to succumb to a darker path in their profession. 
To find out if Catherine and Thomas can successfully keep their own demons at bay long enough to catch the killers circling their worlds, be sure to tune in for the premiere of THOSE THAT KILL on Monday, March 3rd at 10:00 p.m. on A&E.
