“At The Mountains of Madness” tells the first person tale of geologist William Dyer, a professor from Miskatonic University in the USA. He writes to disclose hitherto unknown and closely kept secrets in the hope that he can deter a planned and much publicized scientific expedition to Antarctica. For he has been there and seen the unimaginable horrors that lay beyond the mountains. Originally broadcast on BBC Radio 4Xtra in 2010.
