Doctor Who and Image of the Fendahl — Terrance Dicks

'The Fendahl is death,' said the doctor. 'How do you kill death itself?'

The ultra-modern technology of the Time Scanner combines with the ancient evil of Fetch Wood, and brings to life a terror that has lain hidden for twelve million years.

The Doctor and Leela fight to destroy the Fendahl, a recreated menace that threatened to devour all life in the galaxy.
