Fishing provided an important part of the expedition's food and there was no work Drake liked better. At first he had gone out with face mask and spear gun. But the sharks in this corner of the world were numerous, hungry and aggressive. So, regretfully, he had given up skin diving and set out handlines on the leeward side of the island.

The lines were out now, and Drake lay in the shade of a palm tree, half asleep, his big forearms folded over his chest. His dog, Oro, was prowling the beach in search of hermit crabs. Oro was a good-natured mutt, part airdale, part terrier, part unknown. He was growling at something now.

"Leave the crabs alone," Drake called out. "You'll just get nipped again."

Oro was still growling. Drake rolled over and saw that the dog was standing stiff-legged over a large insect. It looked like some kind of scorpion.

"Oro, leave that blasted—"

Before Drake could move, the insect sprang. It landed on Oro's neck and the jointed tail whipped out. Oro yelped once. Drake was on his feet instantly. He swatted at the bug, but it jumped off the dog's neck and scuttled into the brush.

"Take it easy, old boy," Drake said. "That's a nasty-looking wound. Might be poisoned. I better open it up."

He held the panting dog firmly and drew his boat knife. He had operated on the dog for snake bite in Central America, and in the Adirondacks he had held him down and pulled porcupine quills out of his mouth with a pair of pliers. The dog always knew he was being helped. He never struggled.

This time, the dog bit.
