Entertaining - parallel stories of Maud West's life and career and the author's sleuthing through archives to discover more about her, interspersed with lurid penny-dreadful style stories written by Maud West about her adventures as a lady detective during the Golden Age of Crime.
The first half hooked me more than later when the author was focused on tracking her family tree rather than Maud's work, but I found it engaging and readable.
