During the events of the audio drama "The Secret History", the Monk, distraught over the death of Tamsin Drew, hijacks the Doctor's timeline in an attempt to prevent her death from coming to pass. Using a time-sensitive called Sophia, the Monk attempts to disrupt the Doctor's timeline by causing the Seventh and Sixth Doctors to switch places with the Third and Second Doctors respectively, hoping that the new Doctors will make mistakes and disrupt history. However, Jo Grant and Zoe Heriot are able to help the new Doctors work out what their predecessors would have done and act to preserve history. Eventually the Monk's plan succeeds when he switches the Fifth Doctor with the First, forcing the Fifth to let history be changed by escalating an outbreak of disease in Constantinople in the fifth century to the point where the he must allow an advanced alien race to take action, prompting the Time Lords to take the Doctor out of time and allowing the Monk to insert himself into the Doctor's timeline. Sophia's abilities to see the future prompts her to restore the Fifth Doctor as she sees that the Monk's actions are making history worse in the absence of the Doctor. This allows the Fifth Doctor to arrange for the Monk to be faced with capture by a group of Antoene warriors so that he will be forced to restore the Doctor's timeline to escape this threat. The Monk escapes and vows to return to continue his vendetta against the Doctor.
