Shortly after midnight, her long-term boyfriend, Matthew, had proposed to her under the statue of Eros in the middle of Piccadilly Circus. In the giddy relief following her acceptance, he confessed that he had been planning to pop the question in the Thai restaurant where they just had eaten dinner, but that he had reckoned without the silent couple beside them, who had eavesdropped on their entire conversation. He had therefore suggested a walk through the darkening streets, in spite of Robin’s protests that they both needed to be up early, and finally inspiration had seized him, and he had led her, bewildered, to the steps of the statue. There, flinging discretion to the chilly wind (in a most un-Matthew-like way), he had proposed, on one knee, in front of three down-and-outs huddled on the steps, sharing what looked like a bottle of meths.

It had been, in Robin’s view, the most perfect proposal, ever, in the history of matrimony. He had even had a ring in his pocket, which she was now wearing; a sapphire with two diamonds, it fitted perfectly, and all the way into town she kept staring at it on her hand as it rested on her lap. She and Matthew had a story to tell now, a funny family story, the kind you told your children, in which his planning (she loved that he had planned it) went awry, and turned into something spontaneous. She loved the tramps, and the moon, and Matthew, panicky and flustered, on one knee; she loved Eros, and dirty old Piccadilly, and the black cab they had taken home to Clapham. She was, in fact, not far off loving the whole of London, which she had not so far warmed to, during the month she had lived there. Even the pale and pugnacious commuters squashed into the Tube carriage around her were gilded by the radiance of the ring, and as she emerged into the chilly March daylight at Tottenham Court Road underground station, she stroked the underside of the platinum band with her thumb, and experienced an explosion of happiness at the thought that she might buy some bridal magazines at lunchtime.
