"My! I don't believe Uncle Toby has adopted any orphan children that he wants us to take," Mrs. Martin said. "I can't imagine what he really has, but we'll soon find out."

On and on they rode in the automobile, until, after a while, they reached the small city of Pocono and, a little later, they pulled up in front of Uncle Toby's house. It was a rambling, old mansion that once had looked very nice, but now it was rather shabby and needed painting.

"Here is where Uncle Toby lives," said Daddy Martin. "Do you children remember it?"

"A little," admitted Ted. Neither he nor Janet had been there in years, and Trouble had never visited Uncle Toby.

"I wonder if he's at home," went on Daddy Martin, as he alighted from the automobile.

"There's someone on the porch," said Mrs. Martin. "Oh, it's Mrs. Watson, the housekeeper," she added. "But something seems to be the matter! I wonder what can have happened?"

As Mother Martin spoke a queer little old lady came down off the porch and along the walk, hurrying out to meet the Curlytops, all of whom were now at the front gate.

"Wait! Don't go in! Don't go in!" cried the queer old lady, holding up her hand like a traffic policeman stopping a fast automobile. "Don't go in! They're having a terrible time! Oh, that Mr. Bardeen ever should have gone away and left me to look after 'em! Oh, the trouble I have had! Such trouble! Don't go in! Listen to 'em!"

As she spoke there came strange sounds from the grim old house where Uncle Toby lived! Very strange sounds!
