V.I. Warshawsky, private detective, always acts out valiantly in the face of adversity. Her work is always on the behalf of those less fortunate. She usually ends up hip deep in trouble. She often is out to rid Chicago of bad people who mistreat the elderly. Her intelligence kicks in late through the series that develops caution for this impulsive detective.
