Lt. Grace "Bullets" Billets

Lt. Grace "Bullets" Billets (Amy Aquino) is the commanding officer of Hollywood Homicide. She oversees the men and women whose slogan reads: "Our Day Begins When Your Day Ends." As seasoned law enforcement in her own right, Billets has a special bond with Bosch and well understands the countless rigors of the job. Like Harry, she's a mother of a teenage daughter, and she values the love and light parenting can bring to those whose days are spent staring into the very darkest of the human condition. But as certain lightning rod murder cases remain unsolved, pressures from within and without the bureau begin to mount, jeopardizing her relationship with Bosch and testing her own professional integrity.
