Good evening. Toby Moses, Guardian TV editor here. For those who haven’t heard, we had some terribly sad news this week when our friend, colleague and Line of Duty recapper, Sarah Hughes, died of cancer. The Line of Duty recaps won’t be the same without her – and for the rest of this series we will have an open thread for you to remember Sarah, while rooting out bent coppers and theorising over the identity of H. It’s what she would have wanted.

But first, here’s a tribute to Sarah from her friend and former TV editor Vicky Frost:

Tonight we remember Sarah Hughes who died from cancer, and send our thoughts to her family.

Sarah’s brilliant episode-by-episode recaps have accompanied Line of Duty since its first episode in 2012, filling in the gaps and providing a welcome home for fans to gather to discuss every plot twist and turn. She knew she wanted to write about the show from the very beginning, phoning me to share her excitement about Jed Mercurio’s new police corruption drama.

At the time, I was the Guardian’s TV editor and Sarah and I talked a lot – all the warmth, generosity and energy that infuse her writing also made her fantastic to work and spend time with – and I always looked forward to our conversations. She had a brilliant eye for a hit show, and the previous year had persuaded me that a fantasy epic was going to be the biggest thing on telly, even while I was raising my eyebrows at the idea of mainstream dragons. Of course, Game of Thrones proved to be unmissable, as did Sarah’s writing about it.

But this time, her attention was focused not on a massive HBO number, but a weeknight BBC Two drama. Line of Duty was going to be must-watch television, she promised – the kind of gripping tale that needed to be obsessed over with other viewers.

Sarah, as so often, called it exactly right. Her Line of Duty recaps and the conversations they prompted proved as compelling as the drama itself (sometimes more so). We have all loved reading the theories and debates, celebrating Ted Hastings’ splendid turn of phrase, and discovering the things we had missed in the episode.

So many of us found her clever, funny, insightful recaps to be the perfect companion to the series. Earlier this week, Jed Mercurio paid tribute to Sarah, saying: “Her writing stood out as being inspired by a love of TV, stimulating others to feel the same and adding to her readers’ enjoyment of their favourite programmes. We send our deepest sympathies to her family, friends and colleagues.”

For the remaining episodes we’ll be posting an open thread after the show where we can all share our thoughts and theories. So, how did this interrogation stack up against the best from past series? Why is Davidson embroiled with the OCG? And are we set for a more morose series than expected?
