I was wrong – in my review of Murder on Washington Square (Gaslight Mysteries #4) I said that Sara’s late husband was a police officer.  It appears that was in error –  he was a doctor according to Sarah in Gaslight Mysteries #6.  Read on.

#5 in Gaslight Mysteries 

Back in #4 Sarah met another widower, Richard Dennis, an old friend of her family, whom she dates very casually.  Dennis’ wife was killed 5 years prior by a disease passed on to her by the immigrants housed at the Mission where she volunteered. This thread picks right up again in book 5 where there are new problems at the Mission now a shelter for girls and young women in trouble of various kinds. One morning a young woman is found dead in a nearby park and Sarah and Mulvaney trace her home to the Mission. This twists into a nicely plotted historical thriller.
