Emily Watson and Dominic West star in Appropriate Adult, Love Island pops up in Australia, and there's a documentary about Jackie O and her lesser-known sister . . .
Pick of the day
Appropriate Adult, 9.00pm, TV3
If you didn't see it when it was originally shown on ITV, don't miss this two-part drama that offers a riveting-if-terrifying glimpse into the lives of English serial killer Fred West and his wife Rosemary West.
It stars the unrelated Dominic West - who is scarily impressive as Fred West - Janet Leach as Rosemary West, and Emily Watson as the 'appropriate adult' present during the questioning of Fred West.
After West confesses to killing his daughter, it becomes increasingly obvious to the investigators that the West residence has been the scene of several unspeakable acts, an horrendous house of horrors.
West and Watson both won BAFTAs for their performances.

Sharp Objects, 10.00pm, Sky Atlantic
This is definitely a grower. After a so-so opener, the Amy Adams-starring drama is starting to grip, even though the overused flashback approach to storytelling has become rather clichéd at this juncture.
In this week's episode, the third of eight, Adams' alcoholic, self-abusing journalist Camille relives a recent tragedy as she struggles to piece together the murders in Wind Gap.
Elsewhere, Richard grows frustrated with Chief Vickery’s assumptions regarding potential suspects, and a defiant Amma shows off her wild side to Camille. Meanwhile, their mother Adora continues to admonish Camille for meddling in the investigation and unsettling a town in mourning.
