Murder and History in 1905 Indiana

Jeanne Dams' Murder in Burnt Orange is the last of the series featuring  Hilda Johansson, an immigrant housemaid who has become a lady by marriage.  Hilda is sweltering in a 1905 South Bend, Indiana heat wave.  She is very pregnant, miserable and making everyone around her miserable too.  The family suggests she look into some current local crimes hoping to take her mind off of her discomfort.  They didn't expect her to solve them or it to turn into murder involving family.  This is the last of the series built around actual historical events in the early 20th Century.
