Bloodtide was the twenty-second story in Big Finish's monthly range. It was written by Jonathan Morris and featured Colin Baker as the Sixth Doctor and Maggie Stables as Evelyn Smythe.

A pseudo-historical story, it dramatised a portion of the studies made by Charles Darwin on the Galápagos Islands. It also marked the first appearance of the Silurians on audio.

Publisher's summary[]

The prehistoric Earth is dying. Thunderclouds roll across the skies, cloaking the land in darkness. The seas crash and boil as the rain turns to acid. The remnants of the Silurian race place themselves in suspended animation, deep below the surface.

One day they will awaken and reclaim their world...

The TARDIS has landed on the Galápagos Islands, a desolate outcrop of rocks shrouded in mist and fear.

In the settlement of Baquerizo Moreno, there are rumours that prisoners have been mysteriously disappearing from the gaolhouse. A fisherman has been driven insane by something he saw in the caves. And the Sixth Doctor and Eveyln are not the only new arrivals; there is also a young natural philosopher by the name of Charles Darwin...
