Thicker Than Water was the seventy-third story in Big Finish's monthly range. It was written by Paul Sutton and featured Colin Baker as the Sixth Doctor, Bonnie Langford as Melanie Bush and Maggie Stables as Evelyn Smythe, Gabriel Woolf as Rossiter and Sylvester McCoy as the Seventh Doctor.
A sequel to Arrangements for War, this story is set following Evelyn's first departure from travelling with the Doctor, which is presented in flashbacks in this episode and was previously briefly alluded to in The Juggernauts.
Now elected Principal Triumvir, head of a tripartite government, Rossiter is working to secure a peaceful future for the planet by researching the technology the Killorans left behind. But he has to contend with opposition from his daughter, Sofia, who heads a public campaign demanding the destruction of all alien artefacts.
Politics has caused a rift between father and daughter, and as if that weren't enough, Sofia doesn't approve of her new stepmother either. Emotions soon boil over into violence — violence that seems to have gripped the entire city.
Friendships bind people close, but they say that blood is...
