Talbot Mundy 
The Nine Unknown The Red Flame of Erinpura [EPUB ebook] 

This is the first story in which Chulunder Gon takes a leading position, and previously acted only in the company of other Mundi heroes. The story is about a corrupt Indian ruler who is looking for hidden wealth on his land and has formed a background for the curtains of the gods of Manda. „The buried treasures” are in fact oil deposits. The inspirational author had his own interest in oil in Mexico and the presence of oil in Assam, one of the Indian provinces, which Talbot visited in his youth. Mundi describes the acquisition of wealth in the context of an adventure, about which he simultaneously wrote and tried to live in it.
