Ten minutes later, Austin turned off the main road and drove down a long dirt driveway to a low-slung, clapboard farmhouse. They pulled up next to a dust-covered pickup truck and went onto the front porch. No one answered repeated knocks on the door. They checked the barn and then came back to the porch. Austin tried the door. It was unlocked. He pushed it open. Carina stuck her head in and called out.

“Mr. Benson?”

A low moan came from inside the house. Austin stepped inside and followed a hallway to the cozy living room, where he borrowed a fireplace poker. Walking quietly, they made their way to the end of the hallway. A man lay faceup on the floor of a large studio.

Carina knelt by the man’s side. The blood had stopped oozing from a head wound that was surrounded by angry blue-black skin.

The studio looked as if it had been hit by a monsoon. Filing cabinet drawers were pulled open. Photos were scattered all over the floor. The computer screen had been smashed. Only the National Geographic covers hanging from the walls were undamaged. Austin called 911 and inspected the other rooms. The rest of the house was deserted.

When Austin returned to the studio, Benson was sitting up against the wall. Carina was holding a towel full of ice cubes gingerly against his head. She had wiped the spittle off his lips. His eyes were open, and he was apparently alert.

Benson was a burly, middle-aged man whose skin had been turned to leather by the sun in the exotic places he had worked. His long gray hair was tied back in a ponytail. He wore jeans, a T-shirt, and a film-cartridge vest that was an anachronism in an age of digital photography.

Austin knelt by his side. “How are you feeling?”

“Like crap,” Benson said. “How do I look?”

“Like crap,” Austin said.

Benson managed a weak smile. “Bastards. They were waiting when I came back from my walk to meet with the lady from the UN. Is that you?”

“I’m Carina Mechadi. I’m an investigator with the UNESCO. Mr. Austin here is with the National Underwater and Marine Agency.”

The light of recognition sparkled in Benson’s gray eyes. “Did stories on both your outfits years ago.”

“Tell us what happened after you returned from your walk,” Austin said.

“Saw a car out front. Black SUV. Virginia license plates. I always leave the door unlocked. They were inside going through my stuff.” He grimaced. “In case I pass out again, tell the cops there were four of them. All masked. All with guns. One was a real big guy. Think he was the leader.”

Austin and Carina exchanged glances.

“Did he say anything?”
