“Grantchester” toes an interesting line with religion and religiosity. It avoids it. Yes, the show’s full of religious imagery, complete with beautifully lighted sequences where Tom Brittney gives a lovely sermon and it’s never about being shitty; it’s always about how God’s actually all for the gays and so forth. Because, besides Brittney and Al Weaver, all of the characters on the show are functionally atheists. Even the extremely religious Tessa Peake-Jones. She doesn’t believe the way Brittney and Weaver believe.

It comes out this episode big time with Brittney. Turns out he lied to Charlotte Ritchie last episode, and he’s not okay; he’s not getting better—even worse, we find out God doesn’t talk to him anymore. Now, no spoilers, but we will find out some things about how God speaks to Brittney. Good tortured expression acting from Brittney; if writer Helen Black wasn’t trying to make a certain point, however… well, it’s concerning. Or is it just going to be about the de-faithing of England. Or it’s just a story arc and not a big deal.

God abandoning Brittney is a story arc because they need to get Brittney moping. “Grantchester” was infamously about a mopey vicar who got drunk, listened to jazz, and bedded many, many women while mooning over some shallow girl. Brittney isn’t that mopey vicar. He doesn’t have the mope down, not as an actor, not as a character. When Brittney mopes, it feels like he’s overstepping—“Grantchester”’s supposed to be an ensemble now, and his moping is getting in the way. Also, he’s not being self-destructive; he’s just moping.

He’s not even listening to jazz.

Good mystery this episode. One of Weaver’s halfway house residents turns up dead. Santo Tripodi plays the victim. Halfway house troublemaker Narinder Samra is a too-obvious suspect. “Grantchester” has been letting Samra simmer nicely in the background for a couple episodes, and it really pays off here–Samra’s phenomenal. See, even though the town wants the halfway house gone, when Brittney and Robson Green start investigating, they learn these men mostly just lost their way after a war. So it’s a very personal case.

And let’s not forget Peake-Jones’s husband, Nick Brimble, is paying for the halfway house, which Weaver started after deciding he didn’t want to run his cafe (which Brimble also paid for), leaving boyfriend Oliver Dimsdale to run the cafe and be a photographer. Weaver’s got a tough arc this episode. They leave it open, too, so hopefully, we’ll get some more material for Weaver and Dimsdale before the season’s done.

There are only two more episodes, so if it’s not a subplot by now, it won’t be a subplot.

It also seems like Ritchie won’t figure in prominently, which is too bad. Especially since Brittney’s just moping instead.

Anyway.

Good supporting performances from all the suspects—David Rubin as the guy with a locked room alibi, George Brockbanks as an old collar of Green’s, Jessie Bedrossian as the one female resident in the house, who might be causing love triangles. It’s a really good mystery–definitely the best of the season, with a great finale.

And Simone Lahbib’s still around. She joined last episode as Weaver’s maid, who now gets into competitions with Peake-Jones, which is hilarious. It gives Brimble a little more to do than usual. He’s still mostly an accessory, but he gets to keep pace with an amped-up Peake-Jones.

Outside the ending, which just foretells more sad Brittney… it’s a stellar episode. Director Rob Evans and writer Anita Vettesse cook up a model “Grantchester.”
