The slope begins almost without warning and then keeps rising, and Mara feels it first in the calves before she sees it clearly in the street ahead, and Leith Walk tilts gently upward beneath the lamps and the pavement carries her along its long slow incline while the buildings grow older with every block and the shopfronts thin out into darker windows and narrow doorways set deep into the stone. The air feels colder here, and the wind moves differently between the taller tenements, slipping along the walls and brushing the damp pavement with a faint whispering sound, and she hears the distant murmur of traffic somewhere behind her and the occasional footstep echoing briefly against the closed shutters of late shops, and her own steps fall steady on the wet slabs of pavement—step, step, step—and the sound joins the quiet night rhythm of the city climbing slowly toward its darker center.

And the higher she walks the more the street seems to change character, and the warm spill of takeaway lights gives way to dimmer shop signs and small convenience stores with half-lit windows and narrow pubs where a low hum of voices seeps out through the door each time someone enters or leaves, and she passes a bus stop where the glass shelter reflects her shape for a moment before dissolving again into the reflections of the streetlights, and she keeps her gaze mostly forward because looking too long at reflections always produces the same small disorientation, as if the city were duplicating itself in the wet surfaces and offering her a second world running silently beneath the first.

And somewhere ahead the slope steepens slightly again and the outline of the Old Town begins to gather above the rooftops—dark stone rising against the night sky in uneven layers and narrow silhouettes—and she feels the subtle pull of it, the way Edinburgh seems always to draw its streets upward toward that ridge where the older city stands, and she keeps walking without hurry and without stopping, and the pavement glistens under the lamps like a slow river of reflected light and her steps continue their quiet rhythm along its edge while the wind threads through the buildings and the long climb carries her steadily closer to the darker stones waiting above the crest of the hill.
