As the world faces an impending apocalyptic threat, a man named Peter encounters a bizarre entity known as the Anthropos-Spectre-Beast. Peter finds himself thrust into a series of surreal, cosmic excursions alongside a talking, investigative canine. The narrative operates through a dreamlike, non-linear framework that blurs the boundaries between reality and hallucination. These excursions serve as a vehicle for the protagonist to confront existential dread and the absurdity of human existence in the face of inevitable destruction.

Readers and critics often describe this work as a dense, hallucinatory exploration of the human condition. Discussion frequently centers on the author's use of absurdity to critique the political and social climate of the era. Many highlight the unconventional relationship between the protagonist and the investigator dog as a central anchor for the narrative's shifting tone. The pacing is noted for being deliberately disorienting, which aligns with the book's focus on the instability of reality. Readers who appreciate experimental prose and philosophical inquiry often find the text to be a significant contribution to mid-century European literature.
