Blackwater Falls by Ausma Zehanat Khan (Minotaur Books) “Blackwater Falls,” by Ausma Zehanat Khan (Minotaur Books) When the body of a young Syrian girl is found hanging on the door of a mosque, crucifixion-style, a female Muslim detective is assigned to the case. Inaya Rahman is a member of an elite squad of the Denver Police Department’s Community Response Unit, and the sheriff of Blackwater Falls, where the body is found, is furious that he’s been taken off of the case. There’s good reason for that.
