It's still available to watch for free.

Since airing at the start of January, Channel 4's new drama Kiri has really gripped the British public and that's reflected by the viewing figures that Channel 4 have just revealed. In case you missed it, Kiri follows social worker Miriam Grayson (Sarah Lancashire) whose life gets thrown into disarray after a nine-year-old child in her care - Kiri - goes missing. Throughout the four-part series, Jack Thorne (Harry Potter and the Cursed Child) kept the viewers on their toes because he expertly toyed with the idea that everyone's a suspect. If you haven't seen ti then we're not going to spoil it for you but it has proven to be a massive success. Channel 4 released their consolidated viewing figures today and they've revealed that the show was watched by an average of nearly five million viewers – the largest for a Channel 4 drama since modern records began. The four-part drama starring Sarah Lancashire was watched by an average of 4.9m viewers an audience share of 18.7% (timeshifted viewing) – up 2.1m on the average number of viewers who watched Kiri go out live. And it is the biggest ever drama series on All 4 achieving more than half a million views per episode. Channel 4’s Head of Drama, Beth Willis, said: “Dramas like Kiri - British, topical, complex and illuminating - are exactly the kind of dramas we want to make at Channel 4 and we are thrilled that they’re able to find such a huge and engaged audience. We are honoured that the brilliant Jack Thorne, The Forge, and the astonishing cast felt that Channel 4 was the right home for this thoughtful and gripping drama.“ If you missed out on it during its first run on TV, you can watch it here on All 4. https://www.youtube.com/watch?v=muUgi7KxmaY
