Logopolis
After he takes complete measurements of a British Police Box, the inspiration for the exterior appearance of the TARDIS, the Doctor plans to visit Logopolis to seek the help of the mathematical geniuses there, whose near-mystic incantations of intricate mathematical formulas actually keep the universe from dying a premature death. Thanks to the interference of the Master, the Doctor becomes trapped, and an Australian stewardess named Tegan wanders into the TARDIS, assuming it to be a real Police Box. The Doctor also receives a distress call from Nyssa, whose father has gone missing on Traken. A mysterious ghostly figure appears and disappears, but the Doctor remains silent as to its identity, and the Master finally emerges from the shadows on Logopolis, poised to destroy the universe by eliminating its guardians. All the while, the TARDIS cloister bell counts down last remaining hours of the Doctor’s fourth life.
