"Wait a bit, dear," broke in Ruth. "Let us know a little more about the lost necklace. Why do they think the Gypsies took it?"

"I'll tell you," said The Fox. "You see, this aunt of Nettie's is very, very rich. She comes from California, and she was on to visit the Parsons last spring.

"There was a tribe of Gypsies camping near the Parsons estate. They all went over to have their fortunes told—just for a lark, you know. It was after dinner one evening, and there was company. Nettie's Aunt Rachel had dressed her best, and she wore the necklace to the Gypsy camp.

"That very night the Parsons' house was robbed. Not much was taken except the aunt's jewel-box and some money she had in her desk. The robbers were frightened away before they could go to any of the other suites.

"The next day the Gypsies had left their encampment, too. Of course, there was nothing to connect the robbery with the Gyps., save circumstantial evidence. The police didn't find either the Gypsies or the necklace. But Aunt Rachel offered five thousand dollars' reward for the return of the pearls."

"Just think of that!" gasped Helen. "Five thousand dollars. My, Ruthie! wouldn't you like to win that?"

"Indeed I would," returned her chum, with longing.

"But I guess the Gypsies we were mixed up with never owned a pearl necklace like that. They didn't look as though they had anything but the gaily colored rags they stood in—and their horses."

"What do you know about Gypsies?" asked The Fox.

"A whole lot," cried Helen. "Let me tell you," and she proceeded to repeat the story of their adventure with Queen Zelaya and her tribe. Ruth said nothing during the story; her mind was busy with the mystery of the missing necklace.
