Nancy Drew #55. Mystery of Crocodile Island. Carolyn Keene

A guide asked the group to follow him, and told them about the crocodiles. “The youngest ones have a greenish cast with black markings,” he said. “The half-grown ones are olive green, and the senior citizens are all gray.”

They came to an enclosure with a fifteen-foot-long giant in it. “This old fellow has to stay by himself,” the guide said. “He doesn’t seem to get along with the others. Does anyone have any questions?”

Danny spoke up. “I’ve heard that crocodiles can drown. Is that true?”

“It sure is,” the guide replied. “Both alligators and crocodiles can stay under water until the oxygen in their lungs is used up—alligators longer than crocodiles. But finally they both have to surface.”

“How often do they have to come up?” George asked.

“Oh, I’d say the crocs come up about once every hour. It depends on the water temperature. The warmer the water, the more often they have to breathe. In cold water they can hibernate a lot longer.”

“Do they have to surface to eat?” a man inquired.

“Yes. They can seize their prey underwater, because they have valves in the backs of their throats that close when they open their mouths and the water can’t flow into their lungs. But they have to stick their heads out to swallow.”

The group walked on, and Nancy asked the guide, “What do you do with all these crocodiles?”

“The Ecology Company sells them to various zoos and parks and even to the government,” he replied.

“The government?” George repeated. “What would Uncle Sam do with a lot of crocodiles?”

The guide told her they were distributed to certain areas, “You have probably heard that the crocodile is a vanishing species. We are trying to do our part in seeing that American crocodiles do not become extinct.”

At this remark Bess heaved a great sigh, “Would America really be badly off if it didn’t have any?”

The guide looked at her with contempt in his eyes. “Young lady, if you knew anything about ecology, you would realize how useful they are!”

Bess had no chance to reply because a loud bell rang.

“This is an alarm!” the guide exclaimed. “I must ask you all to get back to the dock as quickly as possible and leave the island!”

“Why?” Nancy asked, disappointed, “Does it mean a crocodile is loose?”

“It could be,” the guide replied. “Now please, ladies and gentlemen, return to your boats without delay!”

The tourists ran. Bess was one of the first, and the others, for once, had trouble keeping up with her. Just before they reached the skiff, a guard at the dock asked them if they had registered when they came in.

“No, we forgot,” Danny said. “I’ll do it now.” He hurried into a small office building and signed his name. Then he entered the girls’ names as Anne, Elizabeth, and Jackie Boonton.

When he came out again, they had already climbed into the skiff. A man in overalls approached the Pirate, pulled out a camera, and snapped their pictures, then hurried away and disappeared among the mangrove trees.

Danny jumped into the skiff and pushed off. “Why was that guy taking your pictures?” he asked.

Nancy looked concerned. “I have no idea. He did it so fast we didn’t have time to turn our backs or refuse.”

“He didn’t photograph any of the other visitors,” George stated. “He singled us out—for a reason!”

Nancy nodded. “I’m sure the top men here realize who we are. Perhaps they wanted our picture to distribute to the members of the gang who haven’t seen us yet!”

George frowned. “This could mean we’ll be harassed by all kinds of people, wherever we go. I’m worried.”

“So am I,” Bess added. “I think we should return to River Heights and get out of this whole dangerous mess!”

“You don’t mean that!” Nancy exclaimed.

“Yes. I do!”

Nancy and George looked at the frightened girl. Finally Nancy said, “If that’s what you want to do, Bess, go ahead. As for me, I’m staying right here and seeing this mystery through!”

“So am I,” George added.

There was silence for several minutes, then Bess gave in. “You know perfectly well that I wouldn’t run out on my friends. But I warn you to be careful. I know I’m not as brave as you arc. I hate to get hurt!”
