It was published in two parts that appeared in the same volume — the very first Doctor Who Yearbook.
- Seventh Doctor
- Fourth Doctor
- Third Doctor
- Jo Grant
- Sea Devils
- Captain Quenell
- Mr. Hardy
to be added
- Despite being blonde in the television series, Jo is depicted as being brunette.
- Jo would briefly see the face of the Fourth Doctor when the Third Doctor temporarily regenerated during his struggle with the Nurazh, describing him as "all teeth and curls", (PROSE: The Touch of the Nurazh) which the Third Doctor would recount when he met an older Sarah Jane Smith who had seen his complete regeneration. (TV: The Five Doctors)
