Snow crunched under the feet of three cloaked figures – a queen, her lady, and a gravedigger – as they hurried along a moonlit path in Windsor Castle's lower ward. The gravedigger pushed a cart that held a slab of marble, his pick and shovel, and some straw. When the trio reached the steps of St. George's Chapel, Queen Mary stopped. She turned her head, pushing aside the fur of her hood, and a gust of wind needled her with crystallized snow. She looked back at her attendants. Was she wrong to trust them with this night's work?
