Dark Cases: The Blood Ruby is an adventure hidden object game. Your worst fears came true the night your father never arrived home. Someone killed him during his latest investigation. As you sort through his remaining possessions you discover his diary recording his last moments - and a strange amulet that sends you hurtling back through time to the day before his murder.
