To mark the recent release of Doctor Who - Doom Coalition Series 3, we travel back through the Eighth Doctor's timestream to 2005, and the main range story Doctor Who: Other Lives, starring Paul McGann, India Fisher and Ron Moody:

London, 1851. Scene of the Great Exhibition of the Works of Industry of All Nations.

Scene also of a plot to un-seat the government, de-throne the monarch and start a republic. If the Duke of Wellington himself is to be believed...

While the Doctor and Charley are drawn into the murky world of nineteenth-century politics, C'rizz struggles to maintain his dignity against growing odds. What begins as an attempt to prevent murder quickly becomes a desperate race to avert revolution. Separated from the TARDIS, the travellers are left to wonder if they'll get their own lives back or be forever entangled with the lives of others.

And who is Mrs Georgina Marlow?

What need does she feel the Doctor can satisfy?

As the Listeners title, Doctor Who - Other Lives is available at £2.99 on Download for the whole of October.

For subscribers to the Big Finish newsletter, this month rather than there being an exclusive first-episode access, watch your inbox for how to access three free Dorian Gray stories: This World Our Hell, The Prime of Deacon Brodie and Murder on 81st Street, all in celebration (or possibly mourning) for this month's The Confessions of Dorian Gray - Series 5. Though do please note these stories contain material which makes them unsuitable for younger listeners.

Vortex magazine will be released slightly later in the month that usual - do bear with us!
