Opening scene of third episode (The Forest of Fear):

1. CAVE OF SKULLS (NIGHT).

THE DOCTOR: Oh, I’m sorry. I’m sorry, it’s all my fault. I’m desperately sorry.

SUSAN: Oh, don’t blame yourself, Grandfather.

THE DOCTOR: Look at those. Look at them.

(He is looking at a pile of skulls.)

IAN: Yes. They’re all the same. They’ve been split wide open.

This was the first in a series of ten scripts of Doctor Who TV stories published by Titan Books between 1988 and 1994, and I guess it’s more interesting now as a case of what you could and couldn’t write then about what was already a decades-old Doctor Who story. There are thirteen pages of introduction (in three chunks) about the concept of the script books, the concept of Doctor Who and the writing of the story, all now well-trodden ground, but I guess less available in 1988. To be honest, I think that even completists could skip this in good conscience. But you can get The Tribe of Gum here.

(Brilliant cover by Dave McKean, though.)
