<p>The countdown to Line of Duty series 7 has officially begun! The BBC has confirmed Robert Carlyle as the first guest star of the series, playing Detective Constable Shaun Massie. Here, we discuss what we know about Shaun's character, other new and returning characters and what we know about the storyline so far. We also do some detective work to try and figure out who else could be joining the cast, and when we could see new Line of Duty on our TV screens. We are currently re-watching every episode of Line of Duty ever, and recapping them one by one. If you fancy a refresher, you can join the fun on patreon.com/shrinepod and click on 'Rewind of Duty'. We are keeping each episode free of spoilers from future episodes, for those who are watching for the first time!</p><p>Support this show <a target="_blank" rel="payment" href="http://supporter.acast.com/shrineofduty">http://supporter.acast.com/shrineofduty</a>.</p><hr><p style='color:grey; font-size:0.75em;'> Hosted on Acast.
