The submersible dove again and coursed along the base of the slide to the left. Austin saw an object on the bottom that was buried except for an exposed, curved edge. He asked Zavala to blow the surface covering off the object with bursts from the vehicle’s thrusters. The technique was commonly used by treasure hunters to uncover a buried wreck. The clouds of sediment eventually settled to reveal the cylindrical shape of a stone column.

“Try going straight up the slope from the column,” Austin advised.

Zavala narrowed the back-and-forth area of coverage, and the vehicle ascended the slide. On one turn, the headlights swept across a triangular pediment that rested at a drunken angle on sections of columns. Austin’s probing gaze zeroed in on a shadow. He pushed himself out of the submersible and swam closer to the cavelike opening. He flashed the beam of his waterproof torch into the cavity.

A second later, Zavala heard Austin’s laughter.

“Hey, Joe, got any kitty treats?” Austin said.

“Talking crazy is a symptom of nitrogen narcosis, my friend.”

“This is not a case of rapture of the deep. I’m looking at a bronze Phoenician cat.”

A feminine squeal of delight filled their earphones. Carina had been listening to the conversation.

“You’ve found it!”

Austin ran the flashlight beam around the cave’s interior. The statue lay faceup, like a corpse stretched out on a funeral bier. The space was about ten feet across and deep, and three or four feet from top to bottom. Austin squeezed through the opening. The figure’s conical hat was dented, and the arms were broken off. Unlike the original statue, the nose was intact.

Austin backed out, and curled his thumb and forefinger in the universal okay signal.

“He’s in good shape for a crushed beer can. Let’s pull him out.”

“There’s line and lift bags in the portside compartment,” Zavala said.

Austin swam to the launch vehicle and pulled a coil of nylon rope from a storage compartment. He tied one end to the rear bumper of the hovering Subvette. Austin tied four open-bottomed lift bags to the line, and went back and attached the free end of the rope to the base of the statue.

He used air from his tank to inflate the bags, then he waved at Zavala, who gunned the thrusters. The line went taut as a violin string. The statue moved several inches. Austin made a throat-slashing motion and swam back to the cavity. The bronze cat attached to the statue’s legs was wedged against an overhead outcropping.

Austin wriggled past the statue and into the cave. His air tanks scraped against the rocks, and there was barely enough space for him to turn around and face out. He pushed down on the statue and told Zavala to start pulling.
