Four Lives
9pm, BBC One
After a recent inquest found infuriatingly major police failings in the case, here is the first episode in a three-part drama about the four victims of the rapist and murderer Stephen Port. Sheridan Smith plays Sarah Sak, who wrote a book about the circumstances around her son’s death, while Stephen Merchant sheds his funny bone to step into an uncomfortably sinister role. Although the programme is bleak in subject, the makers spoke with the families of the victims to make sure their stories were told correctly. Hollie Richardson

The Cabins
9pm, ITV2
Series two of a dating show that did well last year, perhaps because it basically puts the would-be couples in lockdown. They co-habit in log cabins and have an epic 24 hours to decide if they want to prolong the courtship. The twist is that the cabins are now adjacent, allowing gossip with other couples. Jack Seale
