With nothing but a broad expanse of water and no marker to guide them, trying to locate the spot where the Geiger counter had sputtered to life was anything but easy.

“Eddie, I think we’re getting farther away all the time,” Teena said ten minutes later.

“But if we don’t find it now we might never find it again,” Eddie said. “Just a little more. Pull easy on your oar. We’ll circle to the left and—Hey, there it is!”

The rapid clicking through the headset filled his ears. “Hold ’er steady,” he said. He crawled quickly to the bow of the boat, lifted the heavy concrete anchor over the gunwale, and eased it down onto the sand bar with the Manila line attached.

“There. We won’t lose it now,” he said.

“Lose what, Eddie?”

“Whatever’s making the Geiger counter act up,” Eddie said.

“This would be an awful wet place to have to mine for uranium,” Teena said.

“It could be done,” Eddie insisted. “Boy, we must be right over it. Listen to those clicks. And look at that needle jump around.”

Teena looked over the side. “It looks to me like plain old yellow sand down there,” she said.
