After discovering that the average person spends thirty-three years of their life asleep, MATTHEW BLAKE felt the pull of a story. He began extensive research into sleep-related crimes and into the mystery illness known as resignation syndrome, research that sparked a thrilling question: if someone commits murder while sleepwalking, are they innocent or guilty? And so his novel Anna O was born.Before writing fiction, Matthew worked as a researcher and speechwriter at the Palace of Westminster. He studied English at Durham University and Merton College, Oxford.
