TV tonight: the true horror of the Salisbury Poisonings laid bare

The Salisbury Poisonings: A Spy Next Door

9pm, Sky Documentaries
“I said to myself: ‘Don’t worry, nothing happens in Salisbury,’” remembers journalist Emma Volney of her first week in local radio in 2018. “You don’t expect to see two people on a bench foaming at the mouth.” This documentary uses first-hand testimony to walk through the events of the poisoning of former Russian spy Sergei Skripal and his daughter Yulia. The former prime minister Theresa May, intelligence officials and counterterrorism leaders also speak about the incident. Hollie Richardson

Best Medicine

8pm, Sky One
This cosy series about a cranky small-town medic is a faithful remake of Doc Martin – albeit with added American schmaltz. This week sees Maine’s Dr Martin (Josh Charles) deal with an elderly patient displaying a recent pattern of strange behaviour, and primary schooler Peter’s apparent hypochondria. Hannah J Davies

Survivor Australia

9pm, BBC Three
Racing through a mud pit with inevitable injuries is nothing compared with the campfire showdown in the 10th season of the reality hit, billed as heroes v villains. The tribes play beautifully to type, with conservationists and activists working as a team and the self-confessed selfish camp going all-out on the conniving. Hannah Verdier

9pm, U&Gold
Comedian mates Joe Wilkinson and David Earl have a hard time describing their new show in a nutshell. All you need to know is they celebrate one of their favourite sitcoms in each episode, visiting the locations and speaking with its creators and stars. First up, one of Joe’s top picks: Porridge. HR

The outrageous musical vampire romp continues to thrill. Jennifer Ehle guest stars as the fabulous mother of glam rocker Lestat (Sam Reid) and we learn how they both became vampires in 18th-century France. Sure, there’s a bit of incest going on, but the pair together on screen are electric. HR

It Happened to Me: I Was Jailed in Japan for Ketamine

10.15pm, BBC Two
Izabel Rose was a high-functioning ketamine user. Enchanted by Japan, she believed that leaving London would make her go straight. But, as she admits, “addiction doesn’t understand geography”. After phoning a contact about a fix, she was detained in Osaka by the police. So in this documentary, why does she say that was the best day of her life? Priya Elan

“I never had any friends later like the ones I had when I was 12.” With that closing line, this 1986 adaptation of a Stephen King novella cemented its status as the ultimate coming-of-age movie. Its 1950s-set story concerns four boys (including an memorable performance from the late River Phoenix) who set out on a macabre journey to find the body of a missing classmate. Stand By Me was always a classic, but subsequent events – including the tragic death of much beloved director Rob Reiner – have invested rewatches with added poignancy. Ellen E Jones
