Tegan stared in broad-minded Australian disbelief at the police box that had materialized in front of her eyes...
For as long as anyone can remember the chameleon circuit of the TARDIS has been broken — a minor inconvenience which the Doctor now finally gets around to correcting.
But fixing the mechanism involves a visit to Earth and to the planet Logopolis — a quiet little place that keeps itself to itself.
But on this occasion the meddling presence of the Doctor's arch enemy, the Master, ensures the disruption of normality. And even the Master is horrified by the threat of total chaos he unintentionally precipitates.
Logopolis was the final story to feature the fourth Doctor, as played by Tom Baker.
This is a novelization by Christopher H. Bidmead of his own original script.
