Doc’s trip from London to Indochina mentions a stop in Abyssinia before heading across India. A few paragraphs later Afghanistan is mention. Undoubtedly the first reference should have also been Afghanistan.
A large part of the story takes place in Indochina. This is a region that today comprises Vietnam, Cambodia, and Laos. The entire region has many ruins, ancient cities, and areas of archeological interest. A short list would include The Plain of Jars, Temple of Preah Vihear, and Angkor Wat. Of particular interest to readers of The Thousand-Head Man is the Bayon temple in Angkor Thom which is covered with massive carving of heads.
The idea of the vaporized snake venom from spitting cobras is very much akin to that latter used in The Mystic Mullah (January 1935).
