Castrovalva

1983 edition (Released 2019 as part of The Master Collection on Audible)

Still weak and confused after his fourth regeneration, the Fifth 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.
