A dark, moody mystery thriller book cover. A shadowy rain-slicked Bronx street at night under orange sodium streetlights, a lone silhouetted detective figure in a long coat seen from behind. Atmospheric fog and deep shadows between tenement buildings. Cinematic noir lighting, deep blacks, crimson red and gold accents. Title text at top in elegant serif capitals reading "SHADOWS OVER THE BRONX". Author name at bottom in smaller serif capitals reading "JIM COWIE". Professional published novel cover, high contrast, dramatic.
