Starr says his name is Williams and he came from Earth to investigate his sister's death from food poisoning. Makian sends him to the farm's agronomist Benson, who explains that the poisoned food came from several Martian farms and was exported through the domed Wingrad City. Meanwhile Makian and other farm owners have been pressured to sell their farms for ridiculously small sums. Benson also suggests that intelligent native Martians living below the planet's surface are poisoning the food to drive off the human colonists.
