Still weak and confused after his fourth regeneration, the Doctor retreats to Castrovalva to recuperate. But Castrovalva is not the haven of peace and tranquility the Doctor and his companions are seeking. Far from being able to rest quietly, the unsuspecting time-travellers are caught up once again in the evil machinations of the Master. Only an act of supreme self-sacrifice will enable them to escape the maniacal lunacy of the renegade Time Lord. Peter Davison reads Christopher H. Bidmead's complete and unabridged novelisation, first published by Target Books in 1983. 'BBC Audiobooks has chosen well with its books and has taken the right approach with its readers... they benefit from new music and sound effects' - Doctor Who Magazine.
