Sarai Walker's debut novel Dietland was smash hit and made into an AMC TV series, and now she returns with The Cherry Robbers, a twisted, dark gothic novel. Sarai tells us how the novel was inspired by real people and history and how she loves writing fiction that is subversive but "wrapped in a pretty package". And the Two Marks discuss Mr Stay's book launch and his unboxing videos, and how to haggle the best deal from a publisher. Please note: there's no video of the Two Marks on Youtube this week due to broadband issues, but there is video with Sarai's interview.
