"Zero," said the Warden. "I want you to take over X-Ray's hole." She seemed to know that Zero was the fastest digger.

Mr. Pendanski filled the canteens.

The Warden got a pitchfork out of the back of the pickup. She poked it through X-Ray's dirt pile, to see if anything else might have been buried in there as well.

X-Ray got in the pickup. As the truck pulled away, he leaned out the wide window and waved.

"Armpit and Squid, you will keep digging where you have been," she said. "But you're each going to have a helper. Zigzag, you help Armpit. Magnet will help Squid. And Caveman, you'll work with Zero. We're going to dig the dirt twice. Zero will dig it out of the hole, and Caveman will carefully shovel it into a wheelbarrow. Zigzag will do the same for Armpit, and the same with Magnet and Squid. We don't want to miss anything. If either of you find something, you'll both get the rest of the day off, and a double shower. When the wheelbarrows are full, you are to dump them away from this area. We don't want any dirt piles to get in the way."

"After you drop off X-Ray, I want you to bring back three wheelbarrows," she said.

It was easier than digging his own hole. When the wheelbarrow was full, he took it a good distance away before dumping it.

Stanley did as he was told. He carefully looked through all the dirt dug up by Zero, as he shoveled it into a wheelbarrow, though he knew he wouldn't find anything.

After lunch, Zero took over the digging again, and Stanley returned to the wheelbarrow. "There's no hurry," the Warden said several times. "The main thing is not to miss anything."

After a while, she told the boys to switch places, so that Stanley, Zigzag, and Magnet dug in the holes, and Zero, Armpit, and Squid shoveled the excavated dirt into the wheelbarrows.

The Warden remained at the site for the remainder of the day, along with Mr. Pendanski and Mr. Sir, who showed up after a while. Occasionally Mr. Sir would leave to take water to the other groups of campers, but otherwise he and the water truck stayed parked there. The Warden saw to it that nobody in Group D was ever thirsty.

The Warden couldn't keep still. She kept walking around, looking over the boys' shoulders, and sticking her pitchfork through the dirt piles. "You're doing fine, just fine," she told Stanley.

Mr. Sir drove her back to her cabin.

"I wonder how she knew all our names," Stanley said as he walked back to the compound.

"She watches us all the time," said Zigzag. "She's got hidden microphones and cameras all over the place. In the tents, the Wreck Room, the shower."

He realized that was why X-Ray didn't want to talk to him about the gold tube at breakfast. X-Ray was afraid the Warden might have been listening.

One thing was certain: They weren't just digging to "build character." They were definitely looking for something.

Stanley gazed out across the lake, toward the spot where he had been digging yesterday when he found the gold tube. He dug the hole into his memory.

"The shower?" asked Stanley. He wondered if Zigzag was just being paranoid.

The boys dug until each hole was well over six feet deep and wide. Still, it was easier for two boys to dig a six-foot hole than it was for one boy to dig a five-foot hole.

"All right, that's enough for today," the Warden said. "I've waited this long, I can wait another day."

And whatever they were looking for, they were looking in the wrong place.

Stanley had his doubts about that. He didn't think they could make cameras that small. Microphones, maybe.

"The cameras are tiny," said Armpit. "No bigger than the toenail on your little toe."
