„The Devil-Tree of El Dorado” concerns the discovery of the legendary city of Manoa in British Guiana, high atop Mt. Roraima, at that date an incredibly remote part of the world. Most desirable, all the expected thrills of an Atlantean thriller plus some: flying damsels; immortals; a satisfying variety of monsters including the „frightful shape, with its maddening leer and its blood-curdling scream” that welcomes us to the book.
