It's a beautifully evocative article, isn't it? The editors were hoping to get this article published a bit earlier, to coincide with the anniversary of the Princess's death. Unfortunately the new articles software kept throwing things into black holes, and it's taken a bit of time to get everything working. Also, Avalon was making heroic attempts to get copyright permission to publish photos of the Kelly relatives but unfortunately was unsuccessful.
