Publisher's summary
Two more four-part adventures for the Fourth Doctor and Leela:

10.3 The Tribulations of Thadeus Nook by Andrew Smith

It's time for the trip of a lifetime! Come along on one of Thadeus Nook's Time Tours. See history as it really was. Get to witness wars and assassinations! See barbarian warlords right up close!

The Doctor and Leela encounter a most enterprising young gentleman – using time travel for his own financial gain. The Doctor is horrified at the irresponsibility – but it's just the tip of the iceberg.

Because Thadeus Nook is about to learn that history is often best left in the past.

10.4 The Primeval Design by Helen Goldwyn

Dorset, 1830. The Doctor has taken Leela to meet Mary Anning, the noted palaeontologist, but the duo immediately stumble into trouble.

A body has been found in unusual circumstances. Attacked by an animal... but one of a size unknown in the area.

It turns out some things might be better off staying buried.
