Borak and Karissa must find a bubble of air buried in the mud, somewhere beneath Hampstead Heath, to end their relationship. On their descent into London's Underworld they are followed by a film crew and its odious Director, documenting their quest as they scour 24 types of mud for an ending. As they chance upon bones, bricks and talking moles, they must restrain themselves from throttling each other, and falling in love all over again. Chris McCabe's macabre version of Orpheus and Eurydice brings its themes into the present day. Second instalment of an exciting body of work. McCabe's Dedalus shortlisted by Republic Of Consciousness Prize 2019, LRB Bookshop Book of the Week, and praised in Literary Review.
