Book excerpt: The year is 1928 and Prohibition is the law of the land. Caroline Case, who we first met in 2019's The River Rats Murders (9780983575443) 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, legal and otherwise. Although, fiction, Caroline?s story rings true to the fascinating history and colorful characters who lived, loved and died in the "murder capital of the world" during the heyday of Al Capone, speakeasies and Chicago-style jazz.
