Besides being a historical mystery "Murder by Degrees" was also a treatise on the history of social reform, women's rights, and the history of medical education. Set in 1875 Philadelphia, it acknowledged that city's manufacturing and industrial foundations, its multicultural heritage, and its pioneering in the field of medical study.
The protagonist, Dr. Lydia Weston, was a hard working and diligent physician during a time when female doctors were viewed with skepticism by the general public, and often misogyny and derision by male members of the medical profession. In addition, she taught prospective physicians at the Woman's Medical College. Lydia had very a very modest background herself, so was able to empathize with her working-class patients and students. When one of her patients, a chambermaid for a wealthy family, comes to her, they form a friendship when she realizes the girl's intelligence and thirst for knowledge. No wonder then, that Lydia is distraught when the girl's body is found in the Schuylkill River... The police request Lydia aid them in their investigation because of her relationship with the victim. Lydia herself performs the autopsy.
I did find that the medical procedures sometimes detracted from the pace of the mystery's narrative, yet it was interesting in and of itself.
The story was very atmospheric, set as it was in a time when streets were lit with gaslight and operations and autopsies were sometimes lit with oil lanterns.
The book encompassed themes of social injustice, the exploitation of vulnerable people, infidelity, and gender bias.
Part police procedural, part literary mystery, this book made a real impression upon me. The author herself is a physician, so it is written with expert medical knowledge.
In summation, this novel was an enjoyable foray into Philadelphia's rich history as well as a riveting mystery with an intriguing plot. This is a debut novel, and I look forward to reading more in what might become a series. Recommended!
