'The Four Doctors' by Peter Anghelides

The Fifth incarnation of the Doctor has been allowed access to the Vault of Stellar Curios, where the biomechanoid Jariden are at least prepared to consider his warnings about dangerous temporal leakage.

Suddenly, out of nowhere the Daleks attack, unleashing a temporal maelstrom that will not only threaten the Jariden races, but will have dire consequences for the history of the Doctor himself.

Peter Davison (The Fifth Doctor), Colin Baker (The Sixth Doctor), Sylvester McCoy (The Seventh Doctor), Paul McGann (The Eighth Doctor), Ellie Burrow (Professor Kalinda / Lady Cowen), David Bamber (Colonel Ulrik / Whitmore), Nigel Lambert (Michael Faraday / Magran), Nicholas Briggs (Voice of the Daleks), Alex Mallinson (Roboman / Jaridan Device)

Notes:
*Featuring Featuring the Fifth, Sixth, Seventh and Eighth Doctors

*A Big Finish Audio Production

*Working title: 'Reverse Engineering'

*This special release was available free to subscribers whose subscription included the December release 'Demons of Red Lodge and Other Stories'

*Time-placing: all these incarnations of the Doctor are travelling alone, so I have chosen to place them during other periods of solo travel: for the Fifth Doctor, just after 'The Sirens of Time'; the Sixth, just prior to 'The Marian Conspiracy'; the Seventh, towards the end of his travels; the Eighth, between 'The Dying Days' and the start of the audio adventures
