Book excerpt: Over the past half-century Doctor Who has defined science fiction television. The women in the series--from orphans and heroic mothers to seductresses and clever teachers--flourish in their roles yet rarely surmount them. Some companions rescue the Doctor and charm viewers with their technical brilliance, while others only scream for rescue. The villainesses dazzle with their cruelty, from the Rani to Cassandra and Missy. Covering all of the series--classic and new--along with Class, K9, Torchwood, The Sarah Jane Adventures, novels, comics and Big Finish Audio adventures, this book examines the women archetypes in Doctor Who.
