In the Heller series, the lead character is frequently featured interacting with historical figures of the 1930s and 1940.
In Flying Blind, set in the mid-1930s, Heller is hired by book publisher and publicist George P. Putnam to act as a bodyguard for his wife, strong-willed celebrity aviator Amelia Earhart, and at the same time investigate who might be sending her threatening letters.
