The ghost glanced over his shoulder, and at that precise moment, a waitress saw my wave and lifted one finger, indicating she would be with me in a moment. I nodded, smiled and picked up my champagne glass as I turned back to the window. I didn’t look at the ghost again, but I felt his frigid presence a moment later as he glided past my table, still trailing the old couple.

I wondered why he had attached himself to that particular pair and if on some level they were aware of his presence. I wanted to warn them, but I couldn’t without giving myself away. And that was what he wanted. What he desperately craved. To be acknowledged by the living so that he could feel a part of our world again.

Hands steady, I paid my check and left the restaurant without looking back.

Once outside, I allowed myself to relax as I walked back along White Point Gardens, in no particular hurry to seek the sanctuary of my home. Whatever spirits had managed to slip through the veil at dusk were already among us and as long as I remained vigilant until the sun came up, I needn’t cower from the icy drafts and swirling gray forms.

The mist had thickened. The Civil War cannons and statues in the park were invisible from the walkway, the bandstand and live oaks nothing more than vague silhouettes. But I could smell the flowers, that luscious blend of what I had come to think of as the Charleston scent—magnolia, hyacinth and Confederate jasmine.

Somewhere in the darkness, a foghorn sounded and out in the harbor, a lighthouse flashed warnings to the cargo ships traversing the narrow channel between Sullivan’s Island and Fort Sumter. As I stopped to watch the light, an uneasy chill crept over me. Someone was behind me in the fog. I could hear the soft yet unmistakable clop of leather soles against the seawall.
