In this 12th Gaslight Mystery by national bestselling author Victoria Thompson, philosophical conflicts within the deaf community lead to murder most foul. After an influential supporter of deaf education is found dead, NYPD Detective Sergeant Frank Malloy quickly determines the slain man-an advocate of eugenics-was bludgeoned with a trophy. But when Malloy reaches an impasse, he asks his friend Sarah Brandt to help him ferret out the culprit.
