Murder on Marble Row — Victoria Thompson

As a turn-of-the-century midwife in New York City's tenements, Sarah Brandt has seen more than her share of joy and sorrow, birth and death. Now, she's drawn into a politically charged case where her help is not wanted--but is very much needed...

When an explosion kills wealthy industrialist Gregory Van Dyke, Police Commissioner Teddy Roosevelt presumes that anarchists are responsible and personally asks Detective Sergeant Frank Malloy to track them down. Malloy is up to the challenge--but he faces a different kind of challenge when he encounters Sarah Brandt paying a condolence call on the Van Dykes. Faced with the impossibility of ever expressing his true feelings for Sarah, Frank had vowed never to see or work with her again...

For her part, Sarah is glad to be working with Malloy again--though they clash over his conviction that the murder was politically motivated. Frank would like to dismiss her concerns, but whether he likes it or not he needs Sarah's help, because she knows the marble facades of Fifth Avenue hide as many dark and twisted secrets as any tenement on the Lower East Side...
