Midnight pressed its black thumb against the sleeping harbor town. Marla Venn found the kitchen door wide open and blue. Inside, the tall clock kept chewing minutes nobody would confess. A silver knife lay smiling beside the untouched pear tart. The cold rain rehearsed its alibi across every dark windowpane. Detective Iona Crow arrived carrying bitter coffee and old suspicions. She counted six chairs, five wet coats, four open letters. The dead man waited under white linen like a secret. Somewhere far upstairs, a drawer sighed shut without using hands. Iona smiled then because quiet murder had finally introduced itself.
