She consulted her watch. Having allowed her usual margin of time for getting lost, she was a quarter of an hour early. The nondescript black-painted doorway of the office she sought stood to the left of the 12 Bar Café; the name of the occupant of the office was written on a scrappy piece of lined paper Sellotaped beside the buzzer for the second floor. On an ordinary day, without the brand-new ring glittering upon her finger, she might have found this off-putting; today, however, the dirty paper and the peeling paint on the door were, like the tramps from last night, mere picturesque details on the backdrop of her grand romance. She checked her watch again (the sapphire glittered and her heart leapt; she would watch that stone glitter all the rest of her life), then decided, in a burst of euphoria, to go up early and show herself keen for a job that did not matter in the slightest.

She had just reached for the bell when the black door flew open from the inside, and a woman burst out on to the street. For one strangely static second the two of them looked directly into each other’s eyes, as each braced to withstand a collision. Robin’s senses were unusually receptive on this enchanted morning; the split-second view of that white face made such an impression on her that she thought, moments later, when they had managed to dodge each other, missing contact by a centimetre, after the dark woman had hurried off down the street, around the corner and out of sight, that she could have drawn her perfectly from memory. It was not merely the extraordinary beauty of the face that had impressed itself on her memory, but the other’s expression: livid, yet strangely exhilarated.

Robin caught the door before it closed on the dingy stairwell. An old-fashioned metal staircase spiralled up around an equally antiquated birdcage lift. Concentrating on keeping her high heels from catching in the metalwork stairs, she proceeded to the first landing, passing a door carrying a laminated and framed poster saying Crowdy Graphics, and continued climbing.
