In Lincoln's Shadow

Obsession with Lincoln has followed me from Illinois. I have a twelve-volume set of all his collected sayings. My detective Steffen Blaine quotes Lincoln when his emotions need calming. His first wife committed suicide due to post-partum depression. The Lee family's pregnant mother of six closely resembles the symptoms Steffen's wife suffered. Called in to investigate the grandmother's death, Steffen invites Bernie Johnston, a social worker who wants to become a detective, to help him on the case. The youngest girl was one of the cases Bernie worked on. Bernie and Steffen immediately know their association is going to last past this suspicious death.
