Boxcar fans can enjoy three adventures about the Aldens, their dog, Watch, and many other canine companions together in one book!

In The Mystery at the Dog Show, the children help take care of some amazing show dogs at Greenfield's first annual dog contest—but who's trying to ruin the day?

Then, in The Guide Dog Mystery, the Aldens spend time at a service dog school and discover that someone has broken into the kennels to get to one very special dog!

And in The Mystery of the Midnight Dog, the children visit a North Carolina town full of spooky legends, including one about a ghost dog who howls at midnight to warn of danger! Readers will have plenty of fun with the Boxcar Children and their four-legged friends in this new collection.
