A tale of Aztec treasure--of American adventurers, who seek it--of Zoraida, who hides it. Jim Kendric first sees her in a low border saloon dressed as a man. She sits at play with him and wins his fortune and almost his heart. When she next appears he is her prisoner on her ranch in Mexico, where he has gone on a wild expedition in search of a reputed treasure of the Montezumas hidden in the mountains. Nor does he fail to find the treasure, although he comes to it in ways utterly unexpected and through a rapid series of adventures which reveal the fact that the Aztec race is not yet wholly extinct.
