While the Aldens are visiting a friend of Grandfather's at the beach, Benny finds a long-lost piece of a map to a legendary pirate treasure, a discovery that brings unwanted attention from fortune hunters.

While visiting a recent purchase of Grandfather's, a ghost town in the Rocky Mountains, the Aldens encounter a mystery involving a run-down motel and a woman who may be a ghost.

The Aldens discover there's nothing more fun than a drive-in movie. But pranks and other odd things are happening at the Diamond Drive-In, and late at night, a ghost is seen walking around the empty lot. Is the old theater really haunted?

"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?"--Jacket flap.

"The Aldens visit the shore in New Jersey and help out at an amusement pier that is rumored to be unsafe"--

"The Aldens are at Wildcat Crossing, a recreated frontier town full of cowboy fun. But when horses disappear and other pranks threaten to ruin the Wild West show, the Boxcar Children must find out who's the varmint causing all the trouble"--

When the Aldens visit a university campus, they must solve a mystery involving an old library whose stone gargoyles seem to move on their own.

The Alden children are thrilled when a famous orchestra comes to their town to perform, and when an original Mozart score turns up missing, they solve the mystery of its disappearance.

Taking a shortcut through the Greenfield Cemetery, the Aldens stumble across a local superstition which maintains that visitors are required to leave gifts or suffer the wrath of a malevolent ghost, a suspicious tradition that prompts the children to expose the truth.

The Aldens investigate when the arrival of several suspicious characters in Greenfield coincides with a mystery involving a popular boy actor.
