The supplement is divided into two books: a 64-page gamemaster's booklet with accurate background information about The Master, including history, background, and activities, as well as notes on how to give The Master an authentic feel, and statistics for some other opponents of The Doctor, including Daemons, The Nestene Consciousness, Axos and Ogrons; and a 24-page booklet with information for players titled "The Master – CIA File Extracts", supposedly written by the Celestial Intervention Agency.
"[1] Although these two booklets were originally sold together, they are usually found separately on the used book market.
[2] In the May 1986 edition of White Dwarf (Issue #77), Barry Bailey reviewed both The Master and The Daleks, which had been released simultaneously, and said of The Master that it "unaccountably has inferior production to earlier FASA Doctor Who products.
Bailey noted that the statistics given for The Doctor's opponents in this supplement differed in format from those given in The Daleks, commenting, "it would appear that the Dr Who RPG is very poorly co-ordinated as a project."
He also disagreed with some reworking of the Doctor Who canon, calling it an "irritating rewriting of the Dr Who mythos."
