Blue Moon, Black Heart

A valuable vintage crossbow is the instrument of murder, but is it also the reason for murder? Kathleen and Andrea encounter greed, envy, and rage as possible motives when they help Sheriff Ward Sterling investigate the death of one of their relatives. When their prime suspect is shot, they must decide whether he was targeted because he killed their cousin or because he knew who did. When the sisters' lives are threatened, they know they're getting close to finding the killer and hoping they can succeed before they become targets.
