No sooner than he says this than the device is turned on and he and Liz are sucked through a time corridor. However, the window cannot be moved, so it will only show what happens in the room. The Doctor declares the device won’t work for travel, but it will open a time window for observing the past or the future. Liz is both unsure if such a device will work as intended to allow time travel, and worried about the dangers. Then she tells the story of herself and the Third Doctor going to Cambridge to check on Liz’s mentor, who has developed a time dilation device.
Liz explains that she both was and wasn’t involved and that there are no records at UNIT about New Dawn. Liz Shaw is interviewed by a new UNIT soldier about “her involvement” in New Dawn. The story is told by Caroline John and Duncan Wisbey (as Richard) and features the Third Doctor as played by Jon Pertwee on the British television show. The Sentinels of the New Dawn is a story in the Big Finish Companion Chronicles line. Elizabeth (Liz) Shaw, Richard Beauregard, Third Doctor
