Food shortages are the biggest worry, as millions around the globe starve, so Detective Thorn takes a case involving the murder of an influential and powerful man who was on the Board of Directors of Soylent Industries, the company that supplies its "Soylent" cakes of different colors to the masses. It's the only sustainable food item around, and people no longer eat fruit, vegetables, or animals to survive.
