Secrets of the Daleks was the title of a series of three one-page comic series in The Doctor Who Fun Book giving odd insights into the Daleks' various features.
Like Tim Quinn and Dicky Howett's earlier Doctor Who? (and like several other independent comics in the Fun Book), it was a parody of the imagery of the regular Doctor Who universe, although it was visibly not continuity with Doctor Who? as such (as the DWM 81 Doctor Who? strip addressed the same topic as the third Secrets entry with a completely different answer).
