The ninth in the Edgar(r) Award-nominated series featuring midwife Sarah Brandt and Detective Sergeant Malloy in turn-of-the-century New York City.

Sarah Brandt has made her uneasy way to Chinatown to deliver a baby. There she meets a group of Irish women who, completely alone at Ellis Island, married Chinese men in the same predicament. But even as a new century dawns, New Yorkers still cling to their own kind, scorning children of mixed races.

When the new mother's half-Chinese, half-Irish niece goes missing, Sarah knows that alerting the police will accomplish nothing, and seeks the one person she can turn to-Detective Sergeant Malloy.

And when the missing girl is found dead in a Chinatown alley, Sarah and Malloy have ample suspects in her murder-from both sides of Canal Street.
