November, 1942. Betty Ahern is doing her part for the war, working at Bell Aircraft while her older brother and fiancé are fighting overseas, but she really wants to be a private detective like her movie idol Sam Spade. When sabotage comes to the plant, and a suspected co-worker hires her to clear her name, Betty sees it as her big chance. As her questions take her into Buffalo's German neighborhood, Kaisertown, Betty finds herself digging into a group that is trying to resurrect the German-American Bund, a pro-Nazi organization. Have they elevated their activities past pamphlets and party-crashing? When the investigation leads Betty and her two friends into a tangle of counterfeiting and murder, as well as the Bund, the trio must crack the case--before one or more of them ends up in the Buffalo River…wearing concrete overshoes.
