Guaranteed—Forever!

"Guaranteed—Forever!" by Frank M. Robinson is a science fiction novel written in the early 1950s. The story revolves around a man named Manning, who has dedicated his career to exposing fraudulent mail-order schemes, only to encounter a particularly outrageous scam involving a carburetor that allegedly runs on water and promises extraordinary mileage. Set against the backdrop of post-war America, the book engages with themes of deception, technology, and the darker sides of human nature. In the narrative, Manning embarks on an investigation of the Forsythe Carburetor Company, which seems to be at the heart of a convoluted con scheme. As he digs deeper, he discovers that Forsythe is not just a common fraudster but may have connections to something far more enigmatic and potentially dangerous. The tension escalates when Manning narrowly avoids a violent confrontation with Forsythe’s associate, leading him to question the reality of the products being sold. Ultimately, the plot reveals a surprising twist regarding Forsythe's intentions and the potential existence of a time machine, weaving a complex tale that challenges perceptions of reality and hope in the face of dire circumstances, especially when Manning finds a vial labeled "Forsythe's Cancer Cure." This unexpected turn leaves readers contemplating the implications of the products and the disturbing possibility of their origins. (This is an automatically generated summary.)
