“You leave the lights on and I just might let you keep your job,” Giordino uttered back.

Dahlgren smiled and started humming the Merle Haggard standard “Okie from Muskogee,” then closed and sealed the hatch. A few minutes later, he worked the controls of a small crane, lifting the submersible off the deck and depositing it in the center of the ship’s brightly illuminated moon pool. Inside, Pitt signaled for its release, and the yellow cigar-shaped submersible began its descent.

The seafloor was just over a thousand feet deep, and it took the slowly drifting Bloodhound almost fifteen minutes to reach the bottom. The gray-green waters quickly melded to black outside the submersible’s large viewing port, but Pitt waited until they passed the eight-hundred-foot mark before powering up the bright bank of exterior high-intensity lights.

Rubbing his hands together in the slowly warming cabin, Giordino looked at Pitt with mock suffering.

“Did I ever tell you that I’m allergic to the cold?” he asked.

“At least a thousand times.”

“My mama’s thick Italian blood just doesn’t flow right in these icebox conditions.”

“I’d say the flow of your blood has more to do with your affinity for cigars and pepperoni pizzas than with your mother.”

Giordino gave him a thankful look for the reminder and pulled the stubby remains of an unlit cigar out of his pocket and slid it between his teeth. Then he retrieved a copy of the shipwreck’s sonar image and spread it across his lap.

“What’s our plan of attack once we reach the wreck site?”

“I figure we have three objectives,” Pitt replied, having earlier planned the dive. “First, and most obvious, is to try and identify the wreck. We know that the Erebus had a role in the ruthenium that was obtained by the Inuit. We don’t know if the same holds true for the Terror. If the wreck is the Terror, there may well be no clues whatsoever aboard. The second objective is to penetrate the hold and determine if there are any significant quantities of the mineral still there. The third objective is the most tenuous. That would be to search the Great Cabin and the captain’s cabin to determine if the ship’s log still exists.”

“You’re right,” Giordino agreed. “ The log of the Erebus would be the holy grail. It surely would tell us where the ruthenium was found. Sounds like a long shot to hope that it survived intact, though.”

“Admittedly, but far from impossible. The log was probably a heavy leather-bound book stored in a chest or locker. In these cold waters, there’s at least a chance that it’s still in one piece. Then it would be up to the preservationists to determine if it could be conserved and ultimately deciphered.”

Giordino eyed the depth gauge. “We’re coming up on nine hundred and fifty feet.”
