Novelisation
The character of Commissioner Simmonds was killed off by E.C. Tubb in the first Space: 1999 novel Breakaway. As author Brian Ball was unable to rework the story without the scheming politician, ‘Earthbound’ was withdrawn from its intended place in the third Year One Space: 1999 novel The Space Guardians. Ball incorporated certain elements into his adaptation of ‘Missing Link’: Raan's illusory Victor Bergman was given the avaricious intention of seizing an alien ship to travel home.
In 2003, the story was novelised by Tubb and released in Space: 1999 - Earthbound. Minor additions to the story include: (1) As to not violate the novels' continuity, it is stated that Simmonds was left for dead in the confusion of the breakaway, but was resuscitated by Bob Mathias. His broken neck and fractured skull were repaired and the weeks spent recovering in Medical explained his absence; (2) The Kaldorians were found to emit pheromones that make people like them, explaining the instant acceptance of the aliens by Koenig and his boarding party.
