Still the eighties, still the investigation. Though we do get to see David Strathairn and Peter Sarsgaard facing off after the murder. Sarsgaard is very whispery with Strathairn, who’s telling him to investigate Kyle Gallner’s friend, third-billed but rarely onscreen for very long Kodi Smit-McPhee.
This episode—eventually—has Sarsgaard interviewing Smit-McPhee in order to rule him out as a suspect. Unfortunately for Sarsgaard, Smit-McPhee seems really guilty. He lies about visiting Joanna Going—wow, she really gets the crap work in the flashbacks, time and again—and then there’s a goofy knife fight as Smit-McPhee self-aggrandizes in his interview with Sarsgaaard.
Is it an interrogation? Not really. But it seems like there’d be interview tapes or a transcript to dramatize. For a while it seems like Sarsgaard might actually be giving a better performance when his shady cop is actually doing his job—Frank Whaley’s back, playing the voice of reason and good cop here—but it doesn’t last long with Sarsgaard.
He’s bad again before he gets home and the show reveals why he doesn’t pursue valid second suspect Smit-McPhee. See, Smit-McPhee was in another state so good family man Sarsgaard had to abandon pregnant wife Ellen Humphreys to go interview him. In the other state—New Mexico, I think; doesn’t matter—there’s a female detective, which has some unspoken subtext, played by Roberta Colindrez. Colindrez lets Sarsgaard know pretty early on if he wants to play it dirty on this case, she’ll help him. He gets indignant about her suggestion he’s not going to do his job well.
So why does Sarsgaard let Smit-McPhee go after lying and go all in on Gallner—who spends the episode a juvenile in county jail, in the “Snitch Tank,” where Sarsgaard sends him to try to gin up a jail house witness—Sarsgaard goes all in on Gallner because Humphreys has a miscarriage and she’s really needy about it and so he’s not going to neglect her just to get the right killer.
Kind of a wow reveal, kind of an icky, passively misogynistic reveal—see, Sarsgaard would never have been a bad cop if it weren’t for his needy wife and her female problems—but, hey, on par for “Interrogation.”
Given the kid gloves the show usually takes with Sarsgaard’s dirty cop, it’s a bit of a surprise to see them go all in on the miscarriage explanation.
