He’s finishing his chat with the last shivering lookout, Able Seaman Shanks, when Private Wilkes, the youngest of the Marines aboard, comes rushing out from under the canvas. Wilkes has thrown on only two loose layers over his uniform, and his teeth begin chattering even before he delivers his message.

“Mr. Thompson’s compliments to the captain, sir, and the engineer says that the captain should come down to the hold as quick as you might.”

“Why?” If the boiler has finally broken down, Crozier knows, they are all dead.

“Begging the captain’s pardon, sir, but Mr. Thompson says that the captain is needed because Seaman Manson is near to mutiny, sir.”

Crozier stands up straight. “Mutiny?”

“‘Near to it’ were Mr. Thompson’s words, sir.”

“Speak English, Private Wilkes.”

“Manson won’t carry no more sacks of coal past the Dead Room, sir. Nor go down in the hold no more. He says he respectfully refuses, Captain. He won’t come up, but he’s sitting on his arse at the bottom of the man-ladder and won’t carry no more coal back to the boiler room.”

“What is this nonsense?” Crozier feels the first stirrings of a familiar dark Irish anger.

“It’s the ghosts, Captain,” says Marine Private Wilkes through chattering teeth. “We all hear ’em when we’re hauling coal or fetching something from deep stores. It’s why the men won’t go down there below orlop deck no more unless the officers order ’em to, sir. Something’s down there in the hold, in the dark. Something’s been scratching and banging from inside the ship, Captain. It ain’t just the ice. Manson’s sure it’s his old mate Walker, him… it… and the other corpses stacked there in the Dead Room, clawing to get out.”

Crozier checks his impulse to reassure the Marine private with facts. Young Wilkes might not find the facts so reassuring.
