Treasure of the Incas 
A Story of Adventure in Peru

British military officer Harry Prendergast is head over heels in love with the beautiful Hilda Fortescue. But there’s just one catch: Hilda’s family is extremely wealthy, and her father will only give his blessing to suitors who can provide Hilda with the luxurious lifestyle she’s used to. Crushed, Harry begins desperately concocting plans to secure a fortune — a quest that sends him into the mysterious ancient ruins of Peru.
