This week is a conversation with chemist and author Kathryn Harkup about her book 'Making the Monster, The Science behind Mary Shelley's Frankenstein'. Kathryn completed a doctorate on her favorite chemicals, phosphines, and went on to further postdoctoral research before realizing that talking, writing and demonstrating science appealed a bit more that hours slaving over a hot fume-hood. She currently writes a monthly poison blog for the Guardian and gives regular public talks on the disgusting and dangerous side of science. Kathryn's first book was the international best-seller 'A is for Arsenic', which was shortlisted for a Mystery Readers International Macavity Award and a BMA Book Award.
