The Enemy We Don’t Know [EPUB ebook] 
A Homefront Mystery

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.
