In this episode, Adam Biles is joined by writer Dan Richards to talk about his new book Overnight, a deep dive into the world of the night and the people who live and work while the rest of us sleep. From ferry captains and bakers to ICU nurses, researchers, and racing drivers, Richards explores the unseen rhythms and quiet heroism of nocturnal life. The conversation touches on the origins of the book—an unexpected night stranded on a mountain with his father—and how a life-threatening experience during the pandemic reshaped his understanding of vulnerability, care, and community. With warmth, wit, and poetic insight, Richards discusses circadian myths, the industrialisation of sleep, bats, and the benevolence of those who keep the world turning in the dark. Overnight is a tribute to those who inhabit the night, and this conversation shines a light on their often-unseen contributions.
