IN LOWER MANHATTAN there is an improbable point where Waverly Place intersects Waverly Place. It was there I met Veronica, on a snowy, windy night.

She was looking for her keys on the sidewalk in front of a brownstone beside the Convent of St. Zita. She communicated this to me in pantomime turning an invisible key in a lock. She wore a black coat and a wide-brimmed hat from which long black hair streamed over her shoulders. The hat shadowed her eyes, like a mask. I found the keys- a large, odd assortment on an oval key ring. Thanking me with a nod, she put it into her handbag and glanced over her shoulder toward Christopher Street. Following her gaze, I saw nothing but the streetlight on the corner, snow slanting through its cone of light, burying the fire hydrant in a drift.

"Would you walk me to Sixth Avenue?" she asked in a low voice.

Again she glanced up the street, as if there should be someone there, but there was no one. In the silence you could hear the snowflakes brushing through the bare branches of the trees with a metallic rush.

She walked headlong, erect, into the flying snow, her hair blowing out. No one else had walked along that stretch of sidewalk, and we left deep footprints in the snow.

The cars on Sixth Avenue were moving slowly, far apart, their tires crunching the snow. For an instant, she turned her face up to me, and it was illuminated by a flashing sign. Then she flagged a taxi, and slipping an envelope into my hand, jumped in quickly. The taxi sped northward, skid ding around the other cars. The clock tower on the old courthouse for women read 1:15. Up to the right, the Empire State Building was lit up green and white.

The envelope contained an invitation to an opening the following week, at a gallery on Bond Street: Arctic Floes Oil Paintings by Remi Sing. Stuffing it into my pocket, I realized I had not said a single word to this woman. And I had never seen her eyes.
