Special offer releases featuring the Sixth Doctor from the Doctor Who Main Range are available for a week at just £6 on CD or £5 on download each.

In four adventures with Peri (Nicola Bryant), the Sixth Doctor encounters old adversaries including the Rani as well as new, plus the Daleks in a tale where he must be careful not to alter his own history… tune in to the trailer for Masters of Earth here.

Or why not travel with Constance Clarke (first introduced to listeners in The Last Adventure) in three releases on special offer, starting with Criss Cross.

And you can also travel with companion Flip Jackson for three adventures which include the return of Sil (first seen in the Sixth Doctor TV series arc, Trial of a Time Lord).

If you can’t decide between the companions, why not grab an adventure with a whole mix of them? The Last Adventure is a special story which provides a heroic exit for Colin Baker's much-loved Time Lord. Four hour-long episodes are connected by the presence of the Valeyard, the entity that exists between the Doctor's twelfth and final incarnations.

You can pick up The Last Adventure at £25 on CD or £20 on download.
