It's a night of endings as several shows complete their runs – ranging from Goodbye House to The Great British Bake Off and cult Canadian drama Mary Kills People . . .

Pick of the Day

The Great British Bake Off, 8.00pm, Channel 4

It's the final episode of the current GBBO, so for the remaining bakers the stakes couldn't be higher - as Paul Hollywood and Prue Leith set three challenges that will test every aspect of their skills.

In a classic Signature the bakers have the chance to show if their chocolate cake is worthy of winning. The bakers' efforts with a soufflé are under the microscope in the Technical.

Finally, as their families gather outside, in the Showstopper they must create a stunning visual illusion using only cake, sweet bread and biscuits.

May the best baker win!

Love and Hate Crime, 11.35pm, BBC One

The second season of this eye-opening documentary series opens with the story of teenager Abel Cedeno.

After complaining for years of homophobic bullying, he took a knife to his New York school 'for protection'.

Within hours one of his classmates was dead and another seriously wounded. With Abel claiming self-defence, the story caused a sensation in the press and divided New York city, pitting the black community against the gay community.

Filmed with access to the accused and the victim's family in the run-up to the trial, this fascinating murder mystery challenges prejudices and asks: when is a killer the victim, and how does the victim become a villain?

Ar Son Na Poblachta, 7.00pm, RTÉ One

Here's the extraordinary story of George Duff Chalmers.

A windswept bog guarded the secret of the disappearance of George Chalmers for 97 years. Born in Edinburgh, both of his parents died of TB within a few months of each other and he was an orphan at 8 years of age.

He joined the Royal Scots regiment before his sixteenth birthday. He was sent to Ireland and very quickly got caught up in the War of Independence in West Clare.

In June 1921 George was seen in British Army uniform walking alone along a country road. He was captured by an IRA unit. Suspected of being a spy, he was executed and buried in a remote bog.

For nearly 100 years he remained an unknown soldier, but through the dedicated work of a local historian and the power of social media his identity was uncovered.
