Verdict

Deep Water was an excellent start to the Knightfall fourth and final series of UNIT's Brave New World! This has been a really good and underrated spinoff series that I do think has gone under the radar a little. I mean, a download only format for the last two series will certainly contribute to that but it appears that this is the route for a lot of the more niche spinoffs we're getting from Big Finish now. It's certainly better than not getting them at all and this one in particular was a stunning start. It dove straight into where Shatterpoint left off with Ancelyn arriving and I loved the scene that was painted. It was just full of action and conflict that put Bambera in quite a difficult predicament. I liked that Rix and Savarin had knowledge of her past and the way everything tied back to Battlefield was really good. I must say I can't really picture Bambera and Ancelyn getting married but their reunion here was terrific. It did feel like old times of the Seventh Doctor era which was fantastic. There's clearly some things that need sorting out between the pair but they were most glad to find each other once more. The harking back to the silks that Bambera had given Ancelyn as a reminder of his love was really touching and a very powerful moment. Ancelyn coming in the hope of catching the assassins of Queen Guinevere early before Morgaine and Mordred were murdered. Unfortunately, they didn't get to the prison in time and finding out that they had both drowned was certainly not the expected cause of death! I really liked how Ancelyn was able to draw the assassins hired down to the Ladies of the Lake and that really is a tremendous little title. It fit with the other dimensional theme really well and just fitted the mythical realm of Albion magnificently. I continue to be a huge fan of Rix as UNIT's scientific advisor at this point in the timeline and her pairing up with Ancelyn here was really good. He knew how much she was valued by Bambera and that meant he would be protecting her also, even if he was in a pretty dire condition. I am fascinated by the toll taken on him due to crossing dimensions and I wonder if there will be anything reverse heading into the next episode with Bambera and UNIT set to make the opposite journey to Albion. That's a very exciting prospect! I thought hearing Guinevere in action was good and the reveal of Richfield and Ann actually being Ladies of the Lake was good even if it wasn't wholly surprising. It didn't need to be. Their disagreement on the words of Guinevere and having differing opinions on keeping the traitor Ancelyn alive was intriguing to listen to. I thought they were still really strong characters. I do think it's a little bit of a shame that the title reveals how Morgaine and Mordred were killed in their cells as that's the last thing I would think of but it's a cruel method that's for sure! The action here was great and really sparked Bambera into action with her husband back in the fold adding to the dynamic. I get the feeling we're only just getting started when it comes to a cross-dimensional war and that's awfully exciting. Bambera taking the fight to them before they can come to confront UNIT first was great and sets things up for a hugely exciting next episode! I can't wait to explore the world of Albion. But for now, this was an explosive series opener! A brilliant listen.
