Henry, Jessie, Violet, and Benny used to live alone in a boxcar. Now they have a home with their grandfather, and they're exploring a haunted house!

While on a cruise with their grandfather, the Alden children help discover who is behind the mysterious troubles of the ship--disconnected phone lines, engine trouble, a man overboard--and still have fun sightseeing, eating, and swimming.

The Alden family rents a houseboat to drift down the river, and encounters a mystery in the little towns along the river, involving a fast black car.

Henry, Jessie, Violet, and Benny are excited to learn more about raptors when they volunteer at a rehab center for wild birds. But not long after they arrive, a series of strange events makes it seem like someone might be trying to sabotage the center. Who could the culprit be, and why would they want to cause trouble for injured birds?

"Jessie and Benny are participating in the Great Greenfield Bake-Off, a local baking competition for kids. But ingredients get mixed up during the competition and then the power goes out. Is someone trying to put an end to the contest?" --

The Aldens try out a Halloween escape room. The puzzles are fun to solve. But when eerie events start scaring people away, the children find a much bigger case to crack.

People line up around the block to buy Mama Tova's cupcakes. But who could be trying to steal her secret recipe? The Boxcar Children follow clues to a cupcake contest, where they must use their mystery-solving skills to find a thief.

When the Alden children go camping on Blizzard Mountain, a place said to be inhabited by a ghost looking for buried treasure, they begin to think someone or something is trying to scare them off.

When the Aldens visit Peggy and Doc Firmin's farm, they're in for a treat: a behind-the-scenes look at a real teddy bear workshop! But a very rare and valuable bear has disappeared from the toy hospital. Now it's up to the children to track down the teddy thief!

When the Aldens help a friend of their grandfather's to build the world's largest yo-yo, they soon discover that more than one person is trying to prevent them from finishing the job--and for more than one reason.
