Blood and Steel is hands down the best box set of the New Adventures of Bernice Summerfield, while technically told over four different episodes, the fact they all revolve around the same setting and the Cybermen basically makes this a single story. Willkommen opens the set with the Doctor and Benny in 1930s Berlin investigating an anomaly, obviously this is the last place either of them wish to spend time in considering what is on the rise, but something else is exploiting this philosophy and the foreknowledge of events to come in order to build the perfect army. The first half of the story deals more with the grim and ugly setting that was 1930s Berlin and the awful reality of those of less fortunate status which ties in beautifully with how the Cybermen see this as the perfect opportunity to swell their numbers. There's some brutally horrifying moments where the Cybermen process whole groups of people through their conversion machines and how Benny is almost turned into a Cybermen until literally the last second. David Warner gets another highlight moment as the Doctor where he practically terrifies a Cyberman into letting him rescue Benny. Something that does take me out of it through no fault of anyone and not the story itself, this was the first posthumous release following David Warner's death and you'll notice very quickly that his voice has drastically changed since the previous box set, there's even a few moments where I wouldn't even know it was David Warner's voice if I heard them in isolation. I remember hearing the trailer for Once and Future's Time Lord Immemorial and I'd have sworn it was a completely different actor. It's by no means a knock on the story but hearing that gravelly voice and knowing this was so close to the end for him just makes this already difficult story even harder to listen to. But in honour of the man, this like the rest of the episodes in this set is well worth the listen, it's a fantastic opener.
