George Cranleigh

George Cranleigh was an explorer and botanist in the early 20th century. A scion of an aristocratic Oxfordshire family, he was the son of Lady Cranleigh and the elder brother of Charles Cranleigh. He was engaged to Ann Talbot.

Returning from a trip to the Amazon searching for the black orchid in 1924, he was deranged and disfigured. He had been captured, tortured, mutilated and had his tongue cut out by the Kojabe tribe, who considered the black orchid sacred. A friendly tribe led by Latoni returned him home, where his engagement was cancelled.

Lady Cranleigh locked him in a secret section of the house for two years to keep him safe from the outside world with the help of Latoni and one of their servants, Digby.

George was still in love with Ann. In June 1925, he stalked her round the house and murdered Digby and another servant named James. He captured the Fifth Doctor's companion Nyssa, mistaking her for Ann, and took her to the roof. The Doctor and Charles followed him up there. He soon realised that it was not Ann and returned Nyssa to the Doctor, but then fell from the roof to his death. He was the author of the book Black Orchid. (TV: Black Orchid)
