Cover blurb:
The expedition to Zeta Minor began with eight men. Seven were murdered. One survived — but he was not the murderer. DOCTOR WHO lands on the planet at the same time as the expedition’s rescue team, and is immediately taken prisoner — the suspected murderer. But even stranger things soon begin to happen... What terrible creature inhabits this wild, desolate planet, killing mercilessly, lurking in the murky depths of the Black Pool? Will anyone ever be allowed to leave — alive? Terrance Dicks was born in 1935 and educated at East Ham Grammar School and Downing College, Cambridge. After a spell in advertising the author became a full-time scriptwriter, first for radio, then television where for five years he was Script Editor of the ‘Doctor Who’ series. He is now a free-lance author and writes many of the highly successful ‘Doctor Who’ books, as well as an adventure series for boys and girls about the Canadian Mounted Police Force. Terrance Dicks lives in Hampstead, London, is married and has three children. He is an obsessive reader and likes ‘messing about in boats’. |
