The Zoo of Doctor Mengele

The novel "The Zoo of Doctor Mengele" (1989) is the first book in the series of novels about Mino, which has won the love of readers and received critical acclaim. Each book is read as a standalone work, and the... action of one of the books takes place in the near future.
"The Zoo of Doctor Mengele" is a story about the confrontation between the unique fragile world of the tropical forests of the Amazon and the cruel world of business, where there is no place for feelings and mercy; about the terrorist group "Mariposa," which has achieved astonishing results thanks to fearlessness, inventiveness, and caution.
"Mariposa" operates worldwide, leaving a business card at crime scenes — a photograph of a butterfly. The best agents of the world's intelligence services are dispatched to catch the terrorists. What is the secret of "Mariposa"'s invulnerability? What do its members commit their brutal crimes for?
