#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.
THE POWER OF THE DALEKS
Since the next TV Story, THE HIGHLANDERS, is the one where Jamie joins the TARDIS, any audio adventures that feature Ben & Polly can only go in the gap between this story and that one. Stories such as..
TERROR IN TIBET
An Untold Adventure, and prequel to THE ABOMINABLE SNOWMEN, telling how the Doctor, Ben & Polly arrived at Det-Sen Monastery in 1630 and were entrusted with the safekeeping of their holy ghanta…
Given the way the early Second Doctor stories all run into one another, this adventure, and any others with Ben, Polly & Jamie, can only go in the gap between THE MACRA TERROR and THE FACELESS ONES.
THE THREE COMPANIONS
Since this release came out in August 2011, it has to go after THE FORBIDDEN TIME [March 2011] and before THE SELACHIAN GAMBIT [February 2012].
THE GREAT SPACE ELEVATOR
Victoria remarks on Tara’s ‘scandalously immodest skirt’. Given that Telos gets mentioned, and that she is equally disapproving of the attire of the female Britannicus Base staff in THE ICE WARRIORS, I’ve placed this adventure before that one.
THE BLACK HOLE
Jamie mentions THE ICE WARRIORS, putting this story after that one. This story has the Monk sending the Doctor off to the events of THE TWO DOCTORS half way through part two, providing an alternative placement for that story to the infamous Season 6B Theory.
THE EMPEROR OF ETERNITY
Victoria mentions Tibet and the Yeti, putting this after THE ABOMINABLE SNOWMEN.
Since Victoria is studying graphology, as she was doing in THE BLACK HOLE, this story, like THE TWO DOCTORS, also happens before the Doctor and Jamie return to face The Monk.
THE ISOS NETWORK
This takes place immediately after THE INVASION.
FEAR OF THE DALEKS
Zoe says this adventure takes place after the Doctor has shown her the Daleks on the TARDIS scanner at the end of THE WHEEL IN SPACE, putting this adventure somewhere after that one.
SHADOW OF DEATH
Zoe has only recently joined the Doctor and Jamie, so this story has to go as early as possible.
THE GLORIOUS REVOLUTION
Jamie says they are on Earth and it’s still raining, suggesting this follows directly on from the end of THE SEEDS OF DEATH.
TALES FROM THE VAULT
The only indication of when the story Zoe relates in this release takes place is that it happens after THE INVASION.
PRISON IN SPACE
Jamie refers to this story in SECOND CHANCES, so this story has to go before that one.
THE MEMORY CHEATS
Zoe refers to the events of ECHOES OF GREY.
RETURN OF THE YETI
In SECOND CHANCES, Zoe mentions the Yeti, a monster she never met on television, alongside those she did. That suggests she did meet them so this Untold Adventure must happen before the story in which it gets mentioned.
THE UNCERTAINTY PRINCIPLE
Zoe mentions THE KROTONS, putting this story somewhere after that one.
LORDS OF THE RED PLANET
Zoe recognises the Ice Warriors, putting this after THE SEEDS OF DEATH.
THE DYING LIGHT
Stoyn mentions Zoe’s first four trips in the TARDIS, concluding with THE INVASION, meaning this story has to go somewhere after that one.
Zoe refers to both THE SEEDS OF DEATH and THE UNCERTAINTY PRINCIPLE putting this story somewhere after the letter.
Jamie refers to THE SPACE PIRATES, putting this story after that one.
