The Alchemists (audio story)

The Alchemists was the seventieth release in the Companion Chronicles audio range. It was the second story of season 8. It was written by Ian Potter and featured Susan. Chronologically, the events of the story happen before An Unearthly Child. However, the narration by Susan dates at least after the events of Marco Polo.

Some of the greatest scientific minds are gathering here: Einstein, Heisenberg, Planck, Schrödinger, Wigner. The people who will build the future of planet Earth.

But the Doctor and Susan have brought something with them. Something apparently harmless, something quite common. Yet something that could threaten the course of history...
