The Great Bicycle Race Mystery: The Aldens have joined a bicycle race! Three days of riding and camping should be fun for everyone. Even Grandfather has joined the race. But right from the word “Go!” things go wrong: misleading road signs by day and collapsing tents by night. Henry’s first flat tire could be bad luck, but three flat tires point to foul play. But who is playing foul — and why? The Boxcar Children are determined to solve the mystery before they cross the finish line. The Mystery of the Wild Ponies: The Aldens have promised Grandfather a vacation from mysteries during their island visit. But the promise proves hard to keep when things start to go missing. Then an old fisherman tells Benny of the island’s ghost horse, and late that very night Benny sees a mysterious stallion galloping down the beach. Could the ghost horse have something to do with the disappearances? The Mystery in the Computer Game: The Aldens are playing a test version of their favorite game: Ringmaster. But, the characters in the game are giving them strange clues! Is someone using the computer game to tell them something is wrong?
