The year is 1928, and Prohibition is the law of the land. Caroline Case (The River Rat Murders, ISBN 9780983575443, 2019) is now a wealthy, full-fledged private detective in Chicago. With her partner Hannibal Jones, she visits upscale yet scandalous salons near Lakeshore Drive and prowls dangerous and dark underworld dens in sleazy, industrial neighborhoods. Booze, murders, kidnappings and daring rescues abound. Caroline and Hannibal employ the latest tools of forensic science to solve murders and bring the culprits to justice.
