Asylum is a BBC Books original novel written by Peter Darvill-Evans and based on the long-running British science fiction television series Doctor Who. It features the Fourth Doctor and Nyssa (resulting in a slight temporal paradox as the Nyssa featured here comes from a time some time after she stopped travelling with the Fifth Doctor).
