Rain glazed the empty pier while Detective Mara Voss counted footprints circling the body beneath the still broken carnival lights. The victim wore a velvet coat stitched with silver thread and a ticket for the midnight ferry no one saw. A bruised violin lay open beside him its strings wound tight around a key marked with only a borrowed name. Mara smelled salt gin and roses then noticed the tide retreating too fast as if alarmed by her lantern beam. Somewhere above the gulls stopped screaming and every shutter opened one black inch to watch her slowly lift the sheet.
