Austin asked Gunn to steer the ROV around to the stem. As Ensign Kreisman described it, the hull was covered with growth that hid the ship's markings. Gunn poked the vehicle into several nooks and crannies, hoping to come across a manufacturer's metal plate, but they found nothing.

Austin turned to Gamay. “What's our resident nautical archaeologist have to say about this old gal?”

Gamay pinched her chin in thought as she stared at the ghostly images on the glowing screen.

“My specialty was Greek and Roman wooden ships, and if you asked me to ID a bireme or a trireme I might be of more help. I'll venture a few guesses, though.” The camera was moving along the midships section, where the rusty steel plating had buckled and was clear of barnacles. “Those are riveted steel plates. By the 1940s, shipbuilders had switched to welding. The booms indicate that she's probably a cargo ship. She's an old-timer, judging from her lines, maybe built in the late eighteen-hundreds or around the turn of the century.”

Austin asked Gunn to move the ROV around to the damaged side. The ship leaned downhill, and from this angle it looked as if it could come crashing over at any second. Gunn brought the ROV straight in until the hole filled almost the entire screen. The lights probing the ship's innards picked out twisted pipes and steel columns.

“Damage assessment, Rudi?” Austin said.

“From the way those edges are curled, I'd say a projectile hit the engine room. Too high for a torpedo. Probably a shell from a big gun.”

“Who would sink a harmless old freighter?” Zavala asked.

“Maybe someone who thought she wasn't so harmless,” Austin said. “Let's check out the cabin section that Ensign Kreisman told us about.”

Gunn tweaked the controls, and the ROV rose abovedecks. It was clear from the grin on his face that Rudi was having a ball. He brought the vehicle around, taking care not to catch the tether in the foremast or booms. The ROV moved past the bridge, then stopped and hovered in front of a dark rectangular opening. Unlike the ragged cavity in the hull, the edges of the hole were relatively even from the cutting torch. Gunn brought the ROV to within a few feet of the opening. The lights picked out the framework of a bunk and the remnants of a metal chair and desk that lay in a tumbled heap.

“Can we go inside?” Austin asked.
