Most nights, before bed, before it all went wrong, Dominic Van Allen whiled away the last of the evening hours in a pub called The Garden Gate. It was easy to fit in and feel smart there, chatting and drinking with a crowd who passed through in varied states of dishevelment. Dog-walkers brought in sodden dogs. Exhausted junior doctors shambled in after shifts with their sleeves pushed up. There were scarved and suited older men, frail as antique hatstands, and casually dressed professionals with jobs in finance or entertainment who owned expensive homes nearby. “And it’s you rich buggers,” Van Allen marvelled, genially enough, as he eyed the state of their trainers, “who can afford to look the scruffiest.” He wore durable boots, khaki trousers and a leather motorcycle jacket, and could have been mistaken for a bike courier, a builder, maybe a maintenance guy at the hospital next door, where he was known in the staff canteen as someone who would wander in at dawn to buy a discount coffee.
