Rain bruised the harbor windows while Inspector Vale arrived late. Inside the charter office a brass clock pointed past midnight. The owner lay beneath his desk wearing someone else’s coat. No wound showed yet the carpet drank a dark stain. Three ledgers burned in the grate beside untouched green tea. A telephone kept ringing though the line had been cut. Vale pocketed a ticket stub smelling of salt and roses. Outside the night ferry whistled once then swallowed its echo. Across the glass a woman watched without lifting her veil. Vale smiled because dead men rarely misplace their own shoes.
