Edgar Rice Burroughs 
Return of Tarzan 

This follow-up to 'Tarzan of the Apes’ begins where the first novel ended, with Tarzan’s beloved Jane set to marry his cousin. Disappointed in love, Tarzan leaves for Europe, and after a bit of trouble, becomes a spy for the French government. Soon, he finds himself back in the same jungle, in which he grew up, and coincidentally, so does Jane. Duals, attempted murders, espionage, suicide, ancient treasure, a shipwreck, lion attacks and numerous escapes, 'The Return of Tarzan’ (1915) does not lack for anything, and for people left wanting more after the first novel, this is it.-
