He stood by the door, splendid with that strange splendour of moonlight.

His head, ma.s.sive as a mountain, was splashed with silver; and from under great and gloomy brows those vast eyes gleamed, unfathomable.

Over by the port stood Nelson, high and white.

"Mr. Dark," he began in chill and formal voice, "I've sent for you upon the most unpleasant business it's ever been my lot to be mixed up in. Had I only to consider myself, what I have to say would be left unsaid. But I have to think of other and larger issues. If a mischance England might be lost."

The other listened immovable. He was like a smouldering volcano. Every moment Kit expected to see flames leap from his eyes.

Nelson cleared his throat, and continued.

"This young gentleman, Mr. Carvell, has been telling me a strange and terrible tale that affects you."

He turned his eye full-blaze upon the other.

"It is this, Mr. Dark--that you have been paid to sell me to the French."

The giant was stone. Not a muscle twitched. Then the tip of his tongue journeyed round his lips. The lips moved. Kit read the words on them, though no sound came.

They were,

"_Not paid_."

Nelson waited, breathing deep. Receiving no answer, he went on,

"The story so far as I can make it out is this."

Calm and tw.a.n.ging, he stood by the port-hole, and outlined to his alleged murderer-to-be the story of his plot. That mighty man could have crumpled him in one hand, and tossed him through the port-hole. And the giant knew it--so much his eyes betrayed. And the boy, watching from his corner, knew it too. Only the little lopped man talking through his nose across the cabin seemed unaware of it.

The shrill voice ceased. There was silence in the cabin.

"That's the story, Mr. Dark. And I may say I don't believe _one_ word of it."

"Thank you, my lord," came the other's voice, deep and rumbling.

"And if you'll give me your word that it's all moonshine," continued Nelson, "why, I'll ask you to shake my hand and forgive me. And that's an end of the dirtiest bit of business I ever had to handle."

The other's voice stuck in his throat. Out it came at last like m.u.f.fled drums.

"My lord, you're a gentleman."

Nelson came to him with outstretched hand and a wonderful smile.

"Forgive me," he said.

The darkness drifted from the saint's face, leaving behind it evening calm, the stars beginning to shine.

Folding his arms, he bowed deliberately.

Nelson's hand dropped. He stopped short, and his smile died. In a flash the man of action, brisk and curt, had taken the place of the comrade chivalrously admitting a mistake.

"Then I must trouble you to fetch the key of the powder-magazine, and to follow me." He clapped on his c.o.c.ked hat.

The great man turned swiftly.

"One moment, my lord," and he was gone.

III

There was a rush up the companion-ladder, and the noise of running feet on the deck overhead.

"Great G.o.d!" groaned Nelson, ghastly, and flung open the port.

A dark ma.s.s with straggling legs shot past.

There was the plump of a body striking the sea, and crash of showering waters.

"_Man overboard!_" roared a voice from the deck. "_Back tops'ls. Here, sir!_"

A rope coiled out and splashed the water.

Nelson's head was through the port.

The man came up beneath him, and turned to face the ship and his Admiral.

"O, Dark! Dark! Dark!" cried Nelson, and there was agony in his voice.

Dark looked up, the hair plastered about his forehead.

"Nelson," he shouted. "I ask your pardon."

"It's yours, Dark," choked the other. "But O! I thought--I thought you loved me!--every man of you."

"Often and often I could have killed you," gasped the other, bobbing to the seas.

"Rather that than this!" sobbed the great seaman. "Murder's the braver deed."

"I was mad!" groaned the other. "She was in my blood. She was my soul.

She _is_ my soul--the Christ be kind to her! O, if any man in the world can understand, that man should be Lord Nelson."

"No! no! no!" raved Nelson, tossing with his head, stamping with his feet, thumping the port with his fists. "Myself! my wife! my friend!--but _not_ my country! _Not_ that, Dark! _never_ that!"

"_Lively there!_" roared the voice from the deck. "_Lower away_."

There was the splash of a boat.
