This is a prequel novella that I picked up as a kindle freebie awhile back.
It was actually quite cute. The series is set in the early 1920's and features a woman named Ginger Gold and her friend Haley Higgins. Ginger is a 30 year old widow who lost her husband in the war. Haley was Ginger's late father's nurse, and the two struck up a friendship. Ginger also had some involvement in the war herself as an operative of some type.
This novella (183 pages, according to my kindle) finds Ginger and Haley on a ship their way to London. Ginger is going to settle her father's estate, and Haley to further her medical studies.
Along the way the ship's captain winds up dead, and Ginger, along with Haley, and the dashing Inspector Basil Reed sets out to discover the murderer.
Oh! And there's a doggie named Boss (short for Boston)!
Ginger does put me in the mind of Phryne Fisher, and according to the author, she was influenced by the Miss Fisher tv series, so I guess maybe she was supposed to.
