"It's a doll!" he cried. "Flossie, did you leave your doll here?"
"Nope," answered the little twin.
"A doll!" cried Nan. "Oh, maybe it's Helen's talking doll! Let me see, Bert!"
But Bert had already pressed a spring and the doll began to call in a queer phonographic voice:
"Mamma! Papa!"
Flossie and Freddie looked at one another.
"That's the noise we heard when we fell into the cave," they said.
"Then the gypsies did take Helen's doll after all, and brought it with them to this island," said Mr. Bobbsey. "My, but they are great rascals! They took our dog, our cat, our bacon, and Helen's doll."
"But we've got everything back except the bacon," said Bert. "The doll seems to be all right, too, except she hasn't a dress."
"Oh, Helen found that the day she was here on the island," said Flossie. "She found it in an old stump, you know, and I guess maybe the gypsies hid it there, or dropped it."
