"The Shadow Unmasks"

"You remember Kent Allard, the aviator, who was lost a dozen years ago? On that flight to South America? They've located Allard himself! He landed in the Guatemalan jungle, and became the white god of a tribe of Xinca Indians. A Xinca messenger has just shown up in Puerto Barrios, on the Caribbean, with word that Allard is on his way back to civilization. The Classic wants me to go to Guatemala and meet him." - Clyde Burke
