The morning room at Oakridge sat in a perpetual slate-colored twilight, even as noon approached. It was a room designed for retreat, low-ceilinged and heavy with the scent of damp wool and bees-wax. The single window looked out upon a stunted orchard where the gnarled apple branches, encased in a brittle sleeve of glaze ice, clicked against one another in the north wind like dry bones. Inside, the fire in the small hearth did not so much burn as smolder, choking on green wood that hissed and wept thick, resinous tears onto the hearthstone. Beside it sat Julian, his fingers pressed against the cold brass of his pocket watch, listening to the sluggish ticks that seemed to align with the slow drip of melting sleet from the eaves.
