Two teenage girls. One murdered classmate.

And a modern-day witch trial that will divide the nation.

When 18-year-old Christian Shaw is found dead in an Edinburgh park, the city reels - and the shock only deepens when police charge her best friends, Eliza Lawson and Isobel Smyth, with her murder.

As social media explodes and headlines scream for justice, rumours of bullying spiral into something whispers of rituals, obsession, and a teenage pact gone wrong.

Matthew Phillips, a respected heart surgeon, is reluctantly called for jury duty on the case. But as the trial unfolds - and the girls reveal a chilling defence no one saw coming - he begins to question the motives, the evidence, even his own judgement.

Who's telling the truth? Who can be trusted?
And what really happened to Christian Shaw?

Let the Witch Trial begin . . .
