The Camp-Out Mystery — Gertrude Chandler Warner

One warm night four children stood in front of a bakery. No one knew them. No one knew where they had come from.

Henry, Jessie, Violet, and Benny used to live alone in a boxcar. Now they live with their grandfather, and he is taking them on a camping trip.

The children enjoy the camp-out -- setting up the tent, hiking in the woods, and especially making delicious food over the campfire. But some strange things begin to happen. Loud music plays in the middle of the night. Their lantern disappears. And then they receive a frightening note. It looks like the Boxcar Children have another mystery to solve!
