K.C. Constantines Mario Balzic is one of those police chiefs so close to his people that nothing moves or even sits still in his town without his knowing how and why. His town is Rocksburg, a small coal mining town in western Pennsylvania where most of the coal has run out. Tomatoes curiously ripening out of season are the key. It begins at Muscottis Bar, Balzics refuge, when Jimmy Romanelli sells several baskets of tomatoes to Vinnie, Muscottis barkeep. It ends some weeks later after three deaths and a drained, disgusted Balzic, unable to take any satisfaction in his solution of Romanellis murder, the proximate cause for Jimmys twisted passion for growing tomatoes.
