Kerry Drake #3

Kerry Drake, the district attorney's ace sleuth, investigates the case of Francesca Cicero, sister of bootlegger Tony Cicero from the 1920s, who has taken over her brother's liquor racket under the alias "Frisco." After discovering clues at a pram factory and following a cold trail with Sandy and Barr Mallory, Drake pursues the criminal operation, which involves invisible ink stored in a warehouse and references to nitroglycerine. The investigation intensifies as Drake closes in on Frisco's criminal enterprise, uncovering details of her hidden operations and attempting to apprehend her and her accomplices.
