The Transit of Venus (audio story)

Publisher's summary
The year is 1770, and daring explorer Captain James Cook and his crew on the Endeavour are navigating the Pacific Ocean.

Into their midst come strangers: the Doctor and Ian Chesterton, who are believed to have come from Venus. But the TARDIS is lost to them - along with both Susan and Barbara - and Ian makes an enemy of the ship's chief scientist, Joseph Banks.

Why is Banks acting strangely? Could it be that the travellers are not the only visitors from the stars?

Timeline
Though the Big Finish website claims that this adventure comes between The Sensorites and The Reign of Terror, they are in error. All of the regulars are wearing exactly the same clothes at the end of The Sensorites that they are wearing at the beginning of Reign. And the narrative point of the beginning scene of Reign is clearly the same as the last scene of Sensorites. At the end of Sensorites, the Doctor dematerializes the TARDIS with the aim of putting Barbara and Ian off the ship at the very next stop. At the beginning of Reign, the Doctor rematerializes, still intent on getting rid of Ian and Barbara. Transit makes no mention of the spat between the Doctor and his human companions.

Moreover, Transit itself posits the notion that the TARDIS crew have just come from a trip to Venus — something never depicted or hinted at on television.

Thus, this story should be put where all non-televised stories with Barbara, Ian and Susan go: between The Reign of Terror and Planet of Giants.
