As we prepare for the final encounter between the Earth Reptiles and humanity in The War Between the Land and the Sea, we're heading back to Big Finish territory.
We take a look at the making of Bloodtide, the 22nd Big Finish Doctor Who release, which pitted the Sixth Doctor and Evelyn Smythe against the Silurians - and a Myrka.
Joining us to discuss it are writer Jonathan Morris, producer/director Gary Russell, actors Miles Richardson and Helen Goldwyn, plus musician and sound designer Alistair Lock.
