[Gutenberg 44061] • Crossed Trails in Mexico / Mexican Mystery Stories #3

Jo Ann's love of adventure involves her and two school chums in a series of thrilling events in mysterious Mexico.

In "Jitters," their rattly old car, Jo Ann and Peggy and Florence are driving through Mexico. With them are Carlitos and his aunt. The party happens on a band of smugglers who are terrorizing the natives and underpaying them for their workmanship.

The girls expose themselves to many risks and are trapped in a mine while attempting to capture the smugglers. Their anxiety is increased when the desperadoes threaten the life of a revenue officer who is trying to prevent the smugglers from taking their contraband goods across the border into Texas.
