The Murderess is a compelling true crime novel that fictionalizes one of the most famous female killers of the 20th century. 

Beginning in 1931, Winne Ruth Judd takes a train and with her two trunks. When the trunks are discovered to contain bodies, Judd is long gone. Set in such a different era, this is a fascinating story of how Judd got away with murders for so long. I thoroughly enjoyed this one. The perspective shifts contributed well to the character development and even pacing of the plot. 

I think this is a blend of historical, crime, and suspense fiction that will appeal to many readers.
