Mystery on the Mississippi / Kathryn Kenny / 250 pages / St. Louis Challenge

Trixie Belden #15 This is the first Trixie Belden book I have ever read and I must say I was surprised at the affluence of her friends and the kids' freedom. The Bobwhite Club is invited to fly aboard a private jet to St. Louis where Mr. Wheeler is to meet with executives of McDonnel Douglas. The kids look forward to the Air & Space Museum, the St. Louis sights, and the riverboats. When papers are left in the wastebasket of the motel room they check into, Trixie believes they have found evidence of espionage.
