Word of the Law: Death Mask is an exploratory horror visual novel with puzzle and adventure elements. You — a detective who investigates particularly serious crimes involving serial killers. Audrey Parker, a police officer, informs you that a serial killer is at work in the city: several corpses were recently found wrapped in plaster, and all of them were in the form of sculptures. The main suspect — Chad Hill, whose sculpture gallery was burned, and the truth about the arson is hidden because it has to do with local authorities and, of course, money. Now he wants revenge.
