Echoes of Extinction

By Alfie Shaw
Big Finish Productions

Trapped, a haunted monster waits to consume new victims. It needs help. It needs a doctor. Unfortunately, it also needs to kill whoever it meets. Thrust into immediate danger, and on the back-foot, it will take all of the Doctor’s ingenuity to triumph. Two interlinked adventures. Two Doctors. One foe. A double A-side story. Choose which side to play first!

"Oh Doctor, you're going to be so, so terribly alone."
