#1 – Where an Audio Story references a TV Adventure, locate the former as close as possible to the latter.
#2 – If Story A is released before Story B, then A happens before B, unless something in-story says otherwise.
#3 – If a story has the Doctor travelling alone, locate it in the most recently identified Story Gap.
This takes place immediately after CASTROVALVA.
The original novel located itself 3 days after CASTROVALVA, meaning it has to take place after PSYCHODROME.
THE DARKENING EYE
Given the on-screen continuity that exists between BLACK ORCHID and EARTHSHOCK, I’ve placed this after THE VISITATION.
SMOKE AND MIRRORS
The sonic screwdriver has been destroyed, which puts this adventure after THE VISITATION.
ITERATIONS OF I
The Doctor is in the library reading George Cranleigh’s ‘Black Orchid’ book so this takes place after that story.
LAND OF THE DEAD
Nyssa mentions leaving Tegan at Heathrow, so this and any other audios for Five and Nyssa can only go in the Story Gap between TIME-FLIGHT and ARC OF INFINITY.
THE WATERS OF AMSTERDAM
At the end of this adventure the Doctor leaves for his first Solo Side Trip, an errand for the Time Lords…
THE BURNING PRINCE
Having arrived back in Amsterdam, the Doctor decides to let Nyssa & Tegan have some time to themselves, arranging to meet them a few days later by their reckoning. So although this was released after EXCELIS DAWNS it happens before it.
Although this was released before THE BURNING PRINCE, that story reveals Five only made his side-trip in OMEGA before returning to Nyssa and Tegan. So this, and any other Five Solo stories, musat take place afterwards.
THE DIARY OF RIVER SONG SERIES 3:
The Lady In The Lake, A Requiem For The Doctor, My Dinner With Andrew, The Furies.
River mentions that the Doctor is still on his way back to Amsterdam, putting these adventures prior to THE ELITE.
This audio opens with Nyssa thanking the Doctor for letting her and Tegan have some time together, locating the three Lost Stories audios before the later releases in this Story Gap…
Turlough says this story starts just after ENLIGHTENMENT.
This is clearly set soon after ENLIGHTENMENT so I’ve put it after the earlier release FREAKSHOW.
THE FIVE COMPANIONS
For the Fifth Doctor, this adventure takes place halfway through THE FIVE DOCTORS when he uses the Master’s transmat device to escape the Cybermen.
Turlough mentions The Death Zone, putting this after THE FIVE DOCTORS.
AND YOU WILL OBEY ME
The Doctor says the TARDIS was in Little Hodcombe prior to this adventure, putting this after the events of THE AWAKENING.
THE SIRENS OF TIME
The only guide to placement is the fact that the Doctor mentions Tegan & Turlough, putting this somewhere after TERMINUS.
TIME IN OFFICE
The Doctor is on his way back to Frontios, having dropped off the Gravis, when this adventure takes place.
The first release to feature Five and Turlough after Tegan’s departure, this and any other releases where only Turlough is the companion can only go in the gap before Turlough leaves in PLANET OF FIRE.
The first release to feature Five and Peri, this and any other stories where she is the companion can only go in the gap before THE CAVES OF ANDROZANI.
THE VEILED LEOPARD
Erimem mentions her father, referring to THE ROOF OF THE WORLD, putting this adventure after that one.
The Doctor is travelling alone and mentions leaving his companions in Monte Carlo, a direct reference to THE VEILED LEOPARD.
This story is the first to feature just Five and Peri since Erimem’s arrival in THE EYE OF THE SCORPION, but was released before her final story, THE BRIDE OF PELADON, so I’ve put it just after she leaves.
MISSION OF THE VIYRANS
This Five & Peri story was released with THE MIND’S EYE, which is a Five, Peri & Erimem story. As such I’ve located it after EXOTRON.
THE JUDGEMENT OF ISSKAR
The Doctor is heading back to the TARDIS and is calling for Peri when the story begins so I’ve put the ‘Key 2 Time’ trio of adventures after Erimem has left them.
