“That seals it,” Giordino said. “No further proof required. My present state of luck dictates that this has to be the Erebus.”

Despite the minutes ticking down on their bottom time, neither man was ready to give up. They pressed the ROV onward, striking down the single aft passageway, past the cramped officers’ cabins, until finally arriving at a large compartment at the very stern of the ship. Called the Great Cabin, it stretched from beam to beam, offering the one truly comfortable haven for the men of the ship, or at least its officers. Stocked with a library, chess sets, playing cards, and other sources of entertainment, it was also a potential repository for the ship’s log. But like the rest of the vessel, the Great Cabin offered no clues to the ship’s identity.

Scattered across the deck and around an upturned table was a knee-deep pile of books. Lined on wide shelves across each side of the cabin, the large collection of books had smashed through the glass cases during the sinking and been strewn everywhere. Giordino slowly flew the ROV back and forth across the cabin, surveying the wall-to-wall mess.

“Looks like the San Francisco Library after the great earthquake,” Giordino said.

“The ship’s library contained twelve hundred volumes,” Pitt replied, studying the mess with disappointment. “If the ship’s log is buried in there, it will take a couple of fortnights and a good rabbit’s foot to find it.”

Their frustration was interrupted by another radio transmission from Dahlgren.

“Sorry to break up the fiesta, but the big hand on the clock says it’s time for you to begin your ascent,” he said.

“We’ll be on our way shortly,” Pitt replied.

“Fair enough. The captain says to tell you that our shadow has closed to within four miles and is sitting pretty again. I think the captain would feel a whole lot better if you boys got yourselves aboard pronto.”

“Understood. Bloodhound out.”

Giordino looked at Pitt and noticed a look of concern in his green eyes.

“You think that pal of yours from the Miners Co-op is aboard the icebreaker?”

“I’m beginning to wonder,” Pitt replied.

“Let’s try the captain’s cabin and then we’ll ske daddle.”

The captain’s cabin was located off the far side of the Great Cabin and represented a faint hope for containing the ship’s log. But a small sliding door to the cabin was locked and no amount of bumping or cajoling by the ROV would shake it loose. With less than an hour of battery power left and a twenty-minute ride to the surface, Pitt called the survey off and told Giordino to fetch Rover back home.
