"The Crowmarsh Experiment stands as one of the very finest Fourth Doctor Adventures and deserves to be heard again and again."  Doctor Who Vews

"Both Jameson & Baker here take great relish at playing somewhat of a dual role." Indie Mac User

"It’s not often that Big Finish breaks the mould and offers an off-balance character story like this, but the steady script from David Llewellyn and direction from Nicholas Briggs result in each performance amplifying Leela’s conflict to maximum effect as her initial disorientation reaches its inevitable and known end." Doctor Who Reviews 

"This is an outstanding story – our perceptions are played with, the nature of reality is explored and some pretty deep questions are posed about what we perceive to be real. I can just imagine this on TV at the tail end of the Hinchcliffe era getting Mrs Whitehouse up on her high horse about warping children minds – yes its that good." - Planet Mondas

"There’s the Doctor, the TARDIS, the companion, a mystery to be solved, but The Crowmarsh Experiment is so much more than that. If you’re looking for an existential rollercoaster ride, this is the release for you." - Gallifrey Archive

(Note that this release is one of four collected together in Doctor Who - The Fourth Doctor Adventures Series 7A)

This title was released in January 2018. It is currently exclusive as a download to the BF website

When attacked on an alien world, Leela falls unconscious… only to wake in another time, another place.

She is in the Crowmarsh Institute on Earth, in London, in 1978, and everyone is calling her Doctor Marshall. They tell her the world she has known is but a fantasy, a delusion, and that this place is the one that is real.

Surrounded by familiar faces on unfamiliar people, Leela knows what is true and what is false. But how long can she believe when everyone around her says it’s a dream? What’s really happening here?
