Rain hammered the glass while Inspector Mara Vale studied the body beneath the chandelier and counted every silent guest twice. The victim wore evening dress yet his pockets held sand a railway ticket and a key marked with blue ink. Nobody admitted hearing the shot although the orchestra had stopped precisely at midnight when the conservatory doors blew wide open. A crimson cufflink glinted near the roses while Mara's nephew the nervous magistrate lied badly about two missing brandy glasses. Outside thunder erased footprints across the terrace yet inside someone moved behind heavy curtains breathing faster than the old fire.
