The Tenth Doctor meets the constantly curious Charles Darwin in the second of three brand-new novellas starring inspiring characters from history.

Some discoveries should never be made…

When Charles Darwin takes a break from a long sea voyage to look for shells on the Galapagos Islands, he finds two things that really shouldn’t be there. The first is a sunbathing Doctor. The second is a fresh Silurian skull . . .

When more Silurians are discovered by Darwin’s crew – alive, this time – there is pandemonium. And when the island’s volcano starts erupting, years ahead of schedule, it looks like all-out war.

The Doctor has his hands full. Can he keep Charles – and his evolutionary theory – alive?

The history of science is at stake.
