In 1889 New York City, Alyra Merriweather is not the typical type of young lady one would normally find. She is only twenty-five and has accomplished a great deal more than most men and women in society. She has an extraordinarily keen eye for noticing the unusual and intricate aspects of a situation.After witnessing an impossible encounter during her youth, Merriweather has used her unique talents of observation, wit, and medical expertise to aid the local precinct in many of their cases in hopes that she’ll find an explanation for what she saw that frigid November night. Had it been a man, had it been a beast, or had it been both? Now after fifteen years, the brutal murder of a young woman may be her key to finally discovering the truth.
