It was a great square attic with a roof that sloped gradually to the floor from the cupola, which was like the lamp high above in a lighthouse. Like all proper attics it held old trunks, furniture, and all kinds of things. In the drawers of the bureaus and wardrobes were old suits and dresses, and in the trunks, other dresses and suits and old hangings. Andy and Hortense took them out and dressed in them—and played they were a lord and a lady, and pirates, and Indians. Then they sat down to eat the four apples which Hortense had thoughtfully brought with her.

"Where do you suppose the Cat hid the night I followed him and he disappeared?" Hortense asked.

"There are lots of corners to hide in," said Andy, but Hortense was sure that the Cat had some particular place; so Andy and she crawled all around the attic under the eaves, looking behind every trunk and into every corner. Yet they could find no place that seemed especially secret.

"There's no secret corner," said Andy, sitting down beside the big chimney and leaning his back against it.

But as he spoke he suddenly began to disappear through the floor and only by catching the edge of it did he save himself. He and Hortense were too surprised to speak for a moment. Then they knelt on the edge of the opening and peered down.

"It's a trapdoor," said Andy. "We must find out where it goes."

He pushed the door to one side and revealed a little staircase.

"Are you afraid to go down?" Andy asked.

"Of course not," said Hortense. "You go first."

Andy led the way and Hortense followed. A few steps brought them to a small room. It was dark, but the light from the trapdoor enabled them to see a little after a while. There was nothing in the room but a large chest.
