The rain fell softly on the quiet street where the old mansion stood alone at the late dusk in darkness. A broken window glittered near the garden gate, and a cold wind carried the scent of roses through the night. Inspector Hale stepped over the scattered papers, his face grim, his coat heavy with rain and worry under dim lights. The body lay beneath the chandelier, one hand outstretched toward a door that had been locked for years in silence.
