“He said he was happy, but he didn’t look that way to me,” Arden went on. “I thought he looked rather sad, and we don’t even know his name. If that should ever matter.”

“Arden Blake!” Sim exclaimed, “if you make another mystery out of this simple incident, after all we’ve just gone through, I’ll never forgive you! I’m pos-i-tive-ly off mysteries for life.”

“Terry’s right. We’ll probably never see him again. He would certainly know how to hide himself and his dog,” Arden said slowly, and then, stepping on the gas, she drove as fast as she dared in the direction of “Buckingham Palace.”

CHAPTER II
A Man, a Dog, and a Girl

With almost startling suddenness, the little house affectionately known as “Buckingham Palace” popped into view as the car swung round a turn in the road.

A white, two-story house, with brilliant orange awnings, that Terry’s father had bought when Oceanedge had promised to become a thriving seashore resort. But the “plans of men” had gone “agley,” and Oceanedge had never developed beyond Terry’s house, the beginnings of a boardwalk, and a bridge over the small inlet of Bottle Bay.

Arden kept her hand pressed down on the horn, and amid the noise of the horn and Terry’s shrill whistle with forefingers between her lips, announced their arrival.

“Yoo-hoo!” Terry called and once more gave her famous loud whistle.

It was a feat much admired by the other two, who, although they had practised faithfully under Terry’s instruction, were never able to produce as much as a single “toot” from carefully pursed lips.

Terry’s mother, a woman still young and pleasant enough to be Terry’s sister, appeared in the doorway and waved a hand. The girls jumped out and hurried toward her.
