When Nancy joined Bess and George, they were worried about the turn of events.

"Do you suppose," Bess asked, "that somehow the people on Crocodile Island found out that we were coming, and that you're an amateur detective, Nancy?"

"That's possible," Nancy replied. "Anyway, since Dad wants us to go ahead, let's get our seat numbers."

The girls did, then went to the lounge and settled on three seats away from other waiting passengers to discuss what they would do when they reached Key Biscayne.

George said, "Perhaps we should disguise ourselves with wigs and quick-tanning lotions. Bess could become a brunette, I could be a blond, and Nancy a gray-haired old lady."

"Thanks." Nancy laughed. "It would be fun, but the suspects on Crocodile Island have never seen us before. What good would a disguise be?"

After a few moments' thought, Bess spoke up, "You're right, they haven't seen us. But they evidently know who we are. Do you think it would be safer if we changed our names? We could use pseudonyms when necessary."

"What names do you suggest?" George asked.

Nancy smiled. "Suppose I call myself Anne, and Bess can be Elizabeth, and George—"

Quickly George interrupted her. "Not Georgia!" she exclaimed.

Bess laughed. Georgia was her cousin's real name, but she would never allow anyone to call her by it.

"I'll be Jackie," George declared.

The girls discussed a last name and finally decided on Boonton, which was Mrs. Marvin's maiden name.

Nancy looked at her watch. "I'll have time to phone Dad and tell him our new names. He can inform Mr. Gonzales."

When she returned, George said, "Okay, Anne. Our section of seats has been called to board. Let's go!"

Bess grinned. "Oh, Jackie, dear," she said, "You have such brilliant ideas!"
