The mystery at the Calgary Stampede

"The Aldens are on a special vacation up north to see the Calgary Stampede, a cowboy celebration of Canada's frontier spirit! There's a parade through the streets of Calgary, a spectacular stage show, and plenty of fun things to do. But behind the scenes at the festival, an important piece of jewelry goes missing. Can the Boxcar Children find the thief before the big show is ruined?"--Publisher.
