Richard Osman is contorting his 6ft 7in body into what resembles a vertical velvet coffin. It looks uncomfortable, but he is gamely following orders. Photoshoots aren’t his favorite part of the job.

“I would say it’s far enough outside my comfort zone that I can’t even get my comfort zone’s wi-fi,” he says, free of the coffin after the shoot has finished. Posing for photos, international tours, sore hands from marathon-level signings: all this is part and parcel of being one of Britain’s bestselling novelists.
