Return to Paradise

8pm, BBC One
In the second season of this Aussie spin-off from the hugely popular Death in Paradise series, Detective Mackenzie Clarke (Anna Samson) returns to her home town, Dolphin Cove, and there’s a new murder: a scientist who works in a shark research lab is found dead on his boat. Plus, there’s the whole will-they-won’t-they drama with Mackenzie’s forensic pathologist ex-fiance Glenn (Tai Hara). Hollie Richardson

Unreported World

7.30pm, Channel 4
Latin America correspondent Guillermo Galdos sends this timely report from Colombia, where conflict has surged this year between the government and guerrilla groups, and among the groups themselves. Nine years on from a 2016 peace deal, he examines why and how vicious narco violence persists. Hannah J Davies

Borderline

9pm, ITV1
A final two-part story means one more case contrived to unite two detectives from Ireland and Northern Ireland: a hurling player gets a stick to the head, having crossed the border for the match. More dramatically, nervy Northern Irish cop DCI Boyd (Eoin Macken) finally confronts the man he believes shot his father. But what if it’s the wrong bloke? Jack Seale

The Walking Dead: Daryl Dixon

9pm, Sky Max
The second episode of the Walking Dead spin-off and Daryl (Norman Reedus) and Carol (Melissa McBride) have washed up on the Costa da Morte in Spain, not quite making it back home to America. They spot a young couple who take them back to their community, but although Daryl and Carol get a place to stay for a while, it’s not as safe as it seems – and not just because of zombies. HR

How Are You? It’s Alan (Partridge)

9.30pm, BBC One

Alan (Steve Coogan) and Lynn (Felicity Montagu)

Steve Coogan and co triumph again with this exploration of mental health where the wobbliest person on screen is also our guide. Ahead of next week’s finale, freshly single Alan dips a toe into online dating (aided, of course, by Lynn) and religion to help him out of the rut that he swears he isn’t in. HJD

The Graham Norton Show

10.40pm, BBC One
Keira Knightley, now doing her ever so slightly glamorised Guardian reporter impression in silly Netflix thriller The Woman in Cabin 10, is on Graham’s sofa. They’re joined by Malala Yousafzai, Aimee Lou Wood and Chris McCausland. Music comes from Mumford & Sons with Hozier. HR

Film choice

Companion (Drew Hancock, 2025), 8.10am and 8pm, Sky Cinema Premiere

Sophie Thatcher as Iris and Jack Quaid as Josh in Companion

Jack Quaid has become remarkably good at making nasty indie movies in his downtime from The Boys. After the riotously gory Novocaine comes Companion, which is either a violent sci-fi or an extremely accurate representation of what life will be like 30 years from now. Quaid plays Josh, a “nice guy” who starts to have trouble when his sexbot jailbreaks itself. On one hand, Companion is a film about the consequences of coercive control; on the other, it’s a chilling warning about what will happen when the AI we use realises we aren’t very polite to it.

Crawl (Alexandre Aja, 2019), 1.25am, Channel 4
Viewers aren’t exactly wanting for horror movies this Halloween, but if you’re looking for something under the radar that delivers actual scares, Crawl is the movie for you. Ingeniously, Alexandre Aja’s film largely takes place in the crawlspace under a home. Upsettingly for those stuck in it, it is absolutely brimming with alligators. It’s a delicate balance, wringing maximum jeopardy out of the premise without becoming preposterous, but Crawl hits it confidently. Happily, a sequel is on the way … though how they up the ante from this is anyone’s guess. SH
