Travels in Time & Space — David Whitaker

"Doctor Who and the Crusaders"
Back on Earth again, the TARDIS lands Doctor Who and his friends in the midst of the harsh, cruel world of the twelfth-century Crusades. Soon the adventurers are embroiled in the conflict between Richard the Lionheart and the Sultan Saladin, ruler of the warlike Saracens.

Doctor Who's first exciting adventure with the Daleks
Ian Chesterton and Barbara Wright travel with the mysterious Doctor Who and his granddaughter, Susan, to the planet of Skaro in the space-time machine, the TARDIS. There they strive to save the peace-loving Thals from the evil intentions of the hideous Daleks. Can they succeed? And, more importantly, will they ever see their native Earth again?

"Doctor Who and the Zarbi"
Doctor Who lands his space-time machine TARDIS on the cold, craggy planet of Vortis. The Doctor and his companions, Ian and Vicki, are soon captured by the Zarbi, huge ant-like creatures with metallic bodies and pincer claws. Meanwhile, Barbara falls into the hands of the friendly Menoptera, who have come to rid Vortis of the power of the Zarbi.
