Mary Handley, a witty and daring detective from Brooklyn, returns to solve another murder that occurs during the consolidation of Brooklyn and New York City.

Mary's second case begins when she's hired by a young woman who is desperate to know whether her uncle, John Worsham, was murdered. As Mary investigates the curious circumstances surrounding his death, she soon finds herself involved in a dramatic family scandal, several interconnected murders, dangerous political corruption, and an unexpected romance with a very central figure of New York's elite. 

Featuring historic figures like Andrew Carnegie, John D. Rockefeller, and the Vanderbilt family, Brooklyn on Fire takes Mary on a wild journey across the city to uncover not only the truth of one man's death, but to unravel the mystery in several murders -- one linked very close to her own personal world.
