Rain hammered the old rectory. Detective Mara arrived precisely midnight. The body lay beneath chandelier. Father Thomas refused to pray. Blood stained the marble altar. Someone had extinguished every candle. Yet one window remained open. Mara noticed muddy footprints inside. The choir hummed death's lullaby. Nobody admitted hearing the scream.
