Lawson (Bloodtide)

Lawson was the governor of the Galapagos Islands when Charles Darwin visited them. Everyone he sent to be executed in the gaol house were in fact sent to the Silurian base under the islands. As he was in league with Tulok, he knew of events happening on the island when he shouldn't, such as knowing that the Doctor hadn't returned to the Beagle. (BFA:Bloodtide)
