THERE’S something deliciously wrong-footing about hearing Jon Hamm’s voice coming out of a cartoon cop who can’t even make it through a homecoming without landing in the kind of trouble that ruins dinner. But that’s exactly the premise of Grimsburg, the offbeat adult animation that’s now settling into UK viewing.

According to a new report, the series quietly debuted in the UK last week, and tonight it gets a proper chunk of airtime with a triple bill at 10.15pm on Sky One. If you like your comedy with a side of chaos, it’s arriving with intent.

Hamm voices police detective Marvin Flute, a maverick in both temperament and taste for weird cases. Marvin has moved back to his home town with two aims that don’t naturally sit together: reconnect with his family and keep doing what he does best—solving bizarre crimes.

This time, the show leans into the sort of set-up that instantly tells you what flavour you’re in for. Marvin finds himself accused of murdering a judge and has to clear his own name, a plot engine that gives the cartoon licence to ricochet between suspicion, stupidity and swagger.

It’s an appealing fit for Hamm: the straight-faced gravitas, the comic timing, the sense that the voice is taking the absurdity seriously enough to make it funnier. And while the series is clearly pitching itself as “adult” animation, it’s not just about being louder or ruder—there’s a built-in emotional hook in that decision to go back home and try to rejoin a family life that’s presumably moved on without him.

Grimsburg’s UK landing also comes on a night where crime is otherwise going down a far more grounded route, with the finale of Scottish drama Granite Harbour also on the menu. One is a cartoon whodunnit with easy laughs; the other is a straight-faced goodbye.

Either way, the headline takeaway is simple: Hamm has brought a new kind of detective to town—one who’s chasing family peace at the same time as he’s chasing a way out of a murder accusation. It’s messy, it’s strange, and that’s the point.
