“You enjoyed that, didn’t you?” Max was a little paler. Juan shot him a grin. “And have you considered how we’re going to load this thing back on the ferry when we’re done?”

“As you may recall, I got the full insurance package when I filled out the rental forms. Today is not Budget Rent A Car’s lucky day.”

“Should have told me that, otherwise I would have bought retreads rather than new tires.”

Juan blew out a breath like a long-suffering spouse. “We never talk anymore.”

He parked just above the tide line. They had discussed the possibility that the Argentines would anticipate them coming to Pine Island and lay a trap. While Max got some equipment together, Juan scanned the beach for any sign that someone had come ashore recently. The shale tiles looked undisturbed. There were no depressions like the ones his feet made with every step. He knew from talking with Mark and Eric that this was the only place where someone could gain access to the island, so he felt pretty confident that no one had set foot here in a long time.

They had brought battery-powered remote motion detectors that could send a wireless alert to Cabrillo’s laptop. He hid several of them on the beach, facing inland so the motion of waves hitting shore wouldn’t trigger them. It was the best they could do with only two people.

The tract leading to the pit was heavily overgrown, and it taxed the SUV’s off-road capabilities to the limit. Small trees and shrubs vanished under the front bumper and scraped against the undercarriage. They saw evidence that people did continue to visit Pine Island despite the property being posted off-limits. There were several fire pits where local teens camped. Detritus of parties littered the clearings, and long-faded initials were carved in some trees.

“This must be the local version of lovers’ lane,” Max remarked.

“Just so long as you don’t get any ideas,” Juan grinned.

“Your virtue is safe.”

The area immediately around the pit was little changed from when the Ronish brothers came here that first time in December of 1941, with one notable exception. A steel plate had been bolted over the opening into the rock. It was badly rusted, having been exposed to the elements for the past thirty-plus years since it was installed at James Ronish’s insistence, but still remained solid. Mark had warned them about this, and they had come prepared.

The real difference lay just offshore, where concrete pylons had been driven across the mouth of a narrow inlet. When Dewayne Sullivan tried to drain the pit, they had blocked off the bay because it was the most likely source of the water that defeated his pumps every day. The inlet had since refilled, but the water looked stagnant, meaning the cofferdam kept it from mixing with the ocean.
