It's the last-ever episode of gritty Victorian crime drama Ripper Street, while there's a new documentary on RTÉ One about the Sophie Toscan Du Plantier murder

Pick of the day

Ripper Street, 9.00pm, BBC Two

It's amazing that this show – too dark for the Sunday night period drama slot where it started, but not quite cool enough for the cognoscenti – has lasted five seasons, but tonight's is the last-ever episode. It's been a blast.

Reid has finally captured Nathaniel and rid Whitechapel of its most feared monster since Jack the Ripper, but he still has one final enemy to defeat: Assistant Commissioner Augustus Dove.

Even if Reid - who's been superbly played by Matthew Macfayden - is able to bring Dove to justice, can he ever live in peace in Whitechapel, a place that haunts his dreams and nightmares?

New tonight

The Du Plantier Case, 9.35pm, RTÉ One

A late additional to the schedule, this brand new documentary is about the murder of French tourist Sophie Toscan du Plantier, whose killer remains at large more than twenty years after she was beaten to death at her holiday home in county Cork.

Her death remains unsolved, while journalist Ian Bailey was arrested twice in relation to the murder. Bailey wasn't prosecuted for the crime and has always protested his innocence.

Here, du Plantier's son talks about the impact of her death on him and his family. Pierre-Louis was 14 when the French film producer was found brutally murdered.

"It was my last day of being a child," he recalls. "She was everything for me."

Also starting today: 999, What's Your Emergency, 9.00pm, Channel 4;  Who Do You Think You Are USA? 4.45pm, RTÉ One; The Five, Pick

Uncle, Netflix

Originally screened on BBC Three, so it's pretty certain you haven't seen this before. It stars comedian and musician Nick Helm as Andy, a musician who is on the verge of committing suicide when he finds himself looking after his quirky and weird 12-year-old nephew, Errol.

Season two picks up a year after the debut run, Andy and Errol are sneaking around in order to spend time with each other. Andy struggles with writer's block, so Errol tries to get him to detox his mind and body.

Ending tonight

Love Island: The Live Final, 9.00pm, 3e & ITV2

Who watches this rubbish anyway? Plenty of people obviously do as this year's run is longer and tonight's final is on for a mind-boggling 90 minutes!

The £50k prize money will be given to the winning couple, as voted for by the UK public. There's a catch though. If one of the winning pair opts to not share the cash, they get to keep it for themselves, leaving the other with nothing.

Last year Cara De La Hoyde and Nathan Massey won and shared the money between them, but their romance ended earlier this year - which is a lot longer than their celebrity status lasted.
