Gringos is a 1991 book by Charles Portis and the author's fifth novel.
It follows Jimmy Burns, an expatriate American, who during his adventures in Mexico encounters a female stalker, tomb-robbing archaeologists, UFO hunters, and a group of hippies.
[1] Kirkus Reviews wrote: "The double-talk of the cultists is expertly filtered through Portis's lean and muscular prose, and the plot's as tight as a blood-swollen tick.
"[2] Robert Houston of The New York Times called it an "engine of pure delight" and wrote: "If Gringos stops to explore one slough too many from time to time, or to chase a folly farther afield than it really ought to, or to take one more elaborate stitch in the thin cloth of the plot than the fabric can stand, forgive it.
"[3] Philip Herter of the St. Petersburg Times called it a "primitive book in the worst ways" and wrote that it offers "no thrills, no ideas and barely enough style to get you out of the gate.
