11.1 Blood of the Time Lords by Timothy X Atack

The book known as The Dischord Grimoire is an incredibly powerful tome, believed capable of altering the true passage of time itself. And the Doctor has it in the TARDIS.

Wanting to look into this mysterious opus further, he decides to take it to an old friend in The Recusary – a monastery-like retreat on a moon of Gallifrey.

But he’s chosen an inauspicious time to arrive. Something else is visiting the Recusary. And this something hasn’t brought a book with it... but death.

11.2 The Ravencliff Witch by David Llewellyn

The TARDIS lands in Ravencliff, a small town on the English coast that stands in the shade of a newly built power station. And that just happens to be haunted.

Every now and then a spectral figure is glimpsed on the beach - the Ravencliff witch. And every time she appears, it’s the prelude to disaster.

The Doctor has to solve the mystery of her appearances if he wants to prevent a catastrophe. But he won’t have to do it alone – as he has the help of Margaret Hopwood, a renowned sculptor destined to play a big part in his life.
