Jan in India by Otis Adelbert Kline (1974, Book, Illustrated)

Starring one of the best of the Tarzan imitators, this is an enjoyable sequel to the excellent "Jan of the Jungle", aka "Call of the Savage" (the title under which it was made into a movie serial starring a young Noah Beery Jr. who is now best known for playing the dad on "The Rockford Files").
In the original, redheaded Jan Trevor was kidnapped as a small boy & raised in the chimpanzee cage of a private zoo in Florida by a madman who wanted revenge on his mother, but he escaped to the vast rain forests of South America where he was taught English by the lovely Ramona Suarez, adopted daughter of a wealthy Spanish landowner who was also the missing princess of a lost valley colonized by ancient Egyptians.
The sequel is quite a fair bit more ordinary, beginning with Jan being shoved overboard from his family yacht during a trip to India as part of plot by an evil Maharajah to get his hands on Ramona as either his bride or as a human sacrifice to the goddess Kali in the form of a black tiger, & there is a lot of running about in jungles & riding elephants before everyone is reunited for a happy ending & the various villains get their just desserts.
While nowhere near as imaginative as the first volume, it is still a fun read.
The level of thirties racism is kept to a relative minimum, & the Indian background seems to be well researched, a nice touch being words such as "pug" & "mugger" having their Hindu meanings ("footprint" & "crocodile" respectively) although I had to look them up in my dictionary to find that out.
I do, however, have to object to the 'sacrifice to Kali' aspect of the plot. Despite her well-deserved bloodthirsty reputation, from what I understand the Black Goddess is actually seen in that part of the world as a protector of womankind, & the temples of Kali were actually the closest thing to women's shelters they had in India for centuries.
Still, it is a good book & also has the advantage of a nice wraparound cover & interior illustrations by comic book artist Steve Leialoha.
Recommended for Tarzan fans who've read their way through all the Edgar Rice Burroughs books & are still hungry for more.
