Adults called it the nursery. Willy had the larger half, with a double bed, a good-sized basin, a cupboard with mirrored doors, a beautiful window looking down on the courtyard, the fountain, the bronze statue of a roe deer buck. My half of the room was far smaller, less luxurious. I never asked why. I didn’t care. But I also didn’t need to ask. Two years older than me, Willy was the Heir, whereas I was the Spare.
