Thriller writer Susanna is fascinated by human relationships. She can be found people-watching wherever she goes, finding material for her writing. Despite the writer's life, she has an adventurous streak and has swum with whale sharks in Australia, fallen down a crevasse in the French Alps and walked through the sewers of Brighton - not in that order. Her passions include animals — particularly her dogs — walking in the countryside and tennis, which clears her brain of pretty much everything.
