A Murder at Rosamund's Gate by Susanna Calkins

Calkins, Susanna. A Murder at Rosamund's Gate. New York: Minotaur Books, 2013.

When the body of a servant girl in a magistrate's household turns up dead, suspicion falls to the brother of Lucy, a servant girl in the household. He had been dating the murdered servant. The magistrate's son Adam is also briefly suspected because of an accusation. It's one of a series of similar murders. Lucy decides she must try to prove her brother's innocence before he hangs. She finds an ally in Adam. The Black Death and London Fire occur during the course of the novel. While the author does take some liberties with the historical details, she does provide a note specifying those that she has taken. I found this to be well-plotted and highly engaging. The solution was not entirely obvious, but it was a logical one.  Some of the red herrings were rather convincing. This appears to be the first in the series, and I will definitely be looking for future installments. The review is based on an advance e-galley provided by the publisher through NetGalley.
