The careers of New York  City detective 
Simon Ziele and his former partner Captain Declan  Mulvaney went in remarkably different directions after the tragic death  of Ziele’s fiancée in the 1904 General Slocum ferry disaster. Although  both men were earmarked for much bigger things, Ziele moved to Dobson, a  small town north of the city, to escape the violence, and Mulvaney  buried himself even deeper, agreeing to head up the precinct in the most  crime-ridden area in the city.
Yet with all of the detectives  and resources at Mulvaney’s disposal, a particularly puzzling crime  compels him to look for someone he can trust absolutely.  When a chorus  girl is found dead on a Broadway stage dressed in the leading 
lady’s  costume, there are no signs of violence, no cuts, no bruises—no marks at  all. If pressed, the coroner would call it a suicide, but then that  would make her the second girl to turn up dead in such a manner in the  last few weeks.  And the news of a possible serial killer would be  potentially disastrous to the burgeoning theater world, not to mention  the citizens of New York.
Following on the heels of Stefanie Pintoff’s acclaimed and award-winning debut, 
A Curtain Falls  is a moody and evocative tale that follows Ziele and his partners as  they scour the dark streets of early-twentieth-century New York in  search of a true fiend.
