Fred M. White - Mystery of the Four Fingers

A fabulously rich gold mine in Mexico is known by the picturesque and mysterious name of The Four Fingers. It originally belonged to an Aztec tribe, and its location is known to one surviving descendant. Surprises, strange and startling, are concealed in every chapter of this completely engrossing detective story. And through it runs the thread of a curious love story.
