In the silence of a midwinter dusk, the is far off in the deeps of it somewhere a sound so faint that for all you can tell it may be only the sound of the silence itself. You hold your breath to listen. You walk up the steps to the front door. The empty windows at either side of it tell you nothing, or almost nothing. For a second you catch a whiff in the air of some fragrance that reminds you of a place you’ve never been and a time you have no words for. The extraordinary thing that is about to happen is matched only by the extraordinary moment just before it happens. Advent is the name of that moment.
