One to Watch: A Confession, ITV, STV and UTV at 9pm

A Confession, from acclaimed screenwriter, Jeff Pope, starring Martin Freeman, Imelda Staunton, Siobhan Finneran and Joe Absolom tells the story of how Detective Superintendent Steve Fulcher, (Freeman) deliberately breached police procedure and protocol to catch a killer, a decision that ultimately cost him his career and reputation.

In tonight’s final episode in the series Benghazi, Libya provides a welcome change of scenery for former Wiltshire Police Detective Superintendent Steve Fulcher, having resigned from his job in Wiltshire to take on a role as a ‘security consultant’ in November 2014. It is now over three years since he led the investigation that found murdered girls Sian O’Callaghan and Rebecca Godden-Edwards, and Fulcher is happy to be away from Gablecross Police Station.

Things have moved on for Elaine Pickford (Finneran) too, as she continues trying to carry on with her life by making plans to marry her partner Pete (Derek Riddell). The hope that the wedding would provide everyone with some much-needed relief from Sian’s death doesn’t’ however, go to plan as Elaine fears that she might have made a mistake. 

Meanwhile Karen Edwards refuses to give up the fight for justice for her daughter Becky, and continues to embarrass Wiltshire Police at every opportunity over their failure to re-investigate. The pressure forces Wiltshire Police to begin a new investigation into Becky’s murder, but a meeting with the CPS merely confirms to Detective Superintendent Sean Memory (Owain Arthur) that any case against Halliwell would need to be able to use the confession that Christopher Halliwell (Absolom) made to Fulcher.

But there is enough evidence to arrest and charge him, which might smoke out a mistake. The key is for Halliwell to deny murdering Becky (first time around it never got that far) and then the team could ask a new judge to revisit the original ruling that disallowed the confession…

Your Room or Mine?, Channel 4 at 5.30pm

The first episode this afternoon of a series airing each weekday for the next month that sees who has a real flare for interior creation.

Four pairs compete across the week to see who has the best taste in interior design, by making over each other’s homes. In episode one, three interior design loving pairs tackle homeowner Iain’s jaded, old-fashioned living room.

With £250 prize money up for grabs, the design pairs must reimagine Iain’s lounge in purpose-built replica rooms, and restyle it from top to bottom: paint, wallpaper, furniture, window dressing, the works. Sisters in law Lisa and Sam get off to a great start with their deep blue approach but find their look may have been copied by rivals Rachel and Daniel.

Meanwhile children’s entertainer Kelly is left to do most of the work herself, while her husband Mark goes Awol. After five hours of hard graft it’s left to Iain and his brother Pete to choose the winning design, which will be installed for real, in Iain’s home.
