“Goodbye! Goodbye!”

And Peter’s car was off, bearing the last load of campers back to their home town.

Judy Bolton watched them out of sight. They were taking the familiar road, but she and Irene Lang would soon be traveling in the other direction. Pauline Faulkner had invited them for a visit, including Judy’s cat in the invitation, and they were going back with her to New York.

A long blue bus hove into view, and all three girls hailed it, at first expectantly, then frantically when they saw it was not stopping. It slowed down a few feet ahead of them, but when they attempted to board it the driver eyed Blackberry with disapproval.

“Can’t take the cat unless he’s in a crate.”

“He’s good,” Judy began. “He won’t be any trouble——”

“Can’t help it. Company’s rules.” And he was about to close the door when Judy’s quick idea saved the situation.

“All right, he’s in a crate,” she declared with vigor as she thrust the cat inside her own pretty hatbox. The hats she hastily removed and bundled under one arm.

The driver had to give in. He even grinned a bit sheepishly as the girls took their seats, Pauline and Irene together, “Because,” Judy insisted as she took the seat just behind them, “I have Blackberry.”

The other passengers on the bus were regarding the newcomers with amused interest. A ten-year-old boy brought forth a ball of twine and rolled it playfully in Blackberry’s direction. An old lady made purring noises through her lips. Everyone seemed to be nodding and smiling. Everyone except the serious young man across the aisle. He never turned his head.
