He was followed by half a dozen sailors, most of whom carried sub-machine-guns slung across their backs. Four of them paddled the boat across the narrow strip of water towards the ladder that had been dropped over the side of the Kontoro. Two sailors, still standing by the forward hatch of the submarine, carefully paid out a connecting line.

“Carrying a lot of hardware, aren’t they?” Janvier said.

Duclos nodded. “I don’t like the look of this at all. It could be messy enough to rub off on all of us. Perhaps they’re after someone in the crew. An O.A.S. man trying to get out of the country or something like that.”

The sailors came over the side quickly. Three of them unslung their sub-machine-guns and stayed in the well-deck and the young officer mounted the ladder to the upper deck, briskly followed by the other three.

He held out his hand and smiled. “Captain Duclos? My name is Fenelon. Sorry about all this, but I’m only obeying orders, you understand.”

The man who came up the ladder next had a scarred and brutal face and cropped hair. Like Fenelon, he wore a naval reefer jacket and rubber boots, but no cap. He leaned casually against the rail and lit a cigarette. The other two sailors spaced themselves behind Fenelon, machine-guns ready.

Duclos began to feel distinctly uneasy. “Look, what’s going on? What’s this all about?”

“All in good time,” Fenelon said. “You complied with my request to maintain radio silence?”

“Of course.”

“Good.” Fenelon turned and nodded briefly to one of the sailors, who crossed the deck to the wireless room which stood at the rear of the wheelhouse, opened the door and went inside.

A cry of alarm was followed by a burst of fire. A moment later the radio operator staggered through the door, blood on his face. He dropped to his knees and Janvier moved quickly to pick him up.

“The radio/ the man moaned. “He put a burst through it.”

There was a sudden, ugly murmur from the crew in the well-deck that was answered by a volley of firing, bullets hissing through the steel rigging lines. Duclos glanced over the rail and saw that a heavy machine-gun had been mounted on a swivel on the rim of the conning tower. Even allowing for the difference in height between the two vessels, it was still capable of reducing most of the deck area of the Kontoro to a bloody shambles.

He turned slowly, his face pale. “Who are you?”

Fenelon smiled. “Exactly what we seem, Captain. The commanding officer and crew of the submarine L’Alouette. Under special orders, but serving France, I assure you.”

“What do you want?” Duclos said.

“One of your passengers, Pierre Bouvier. I understand he is traveling with you as far as Madeira?”

Duclos's rage, hardly contained, flooded out in a roar of anger. “By God, I’ll see you in hell first! I’m still captain of this ship.”

Still leaning comfortably against the rail, Jacaud pulled the Liiger from his pocket and shot him neatly through the left leg. Duclos screamed as the heavy slug splintered his knee-cap and rolled over on the deck, face twisted in agony.

“To encourage the rest of you,” Jacaud said calmly. “Now get Bouvier up here.”

As Janvier turned, a quiet voice said: “No need, monsieur. He is here.”

The man who stepped out of the saloon companionway was well past middle age. Tall and thin with stooping shoulders, he had the angular bony face of the ascetic and thinning grey hair. He wore a raincoat over pyjamas and a small grey-haired woman clutched his arm fearfully. Behind them, two other passengers, clothes hastily pulled on, hesitated in the doorway.

“You are Pierre Bouvier?” Fenelon demanded.

“That is correct.”

Jacaud nodded to one of the sailors. “Bring him over here.”

The woman’s voice lifted at once, but Bouvier quietened her and allowed himself to be led forward. The sailor placed him with his back to the rail and went and stood beside Jacaud.

“What do you want with me?” Bouvier said.

“A month ago at Fort-Neuf you were public prosecutor at a trial,” Fenelon said. “A trial at which six good friends of ours received the death sentence.”

“So, the O.A.S. is in this?” Bouvier shrugged. “I did my duty as I saw it. No man can do more.”

"You will, I am sure, allow us the same privilege, monsieur.” Fenelon produced a document from his pocket, unfolded it and read rapidly. “ "Pierre Bouvier, I must inform you that you have been tried in your absence and found guilty of the crime of treason against the Republic by a military tribunal of the Council of National Resistance."

He paused and Bouvier cut in gently, “And the sentence of the court is death?”

“Naturally,” Fenelon said. “Have you anything to say?”

Bouvier shrugged and an expression of contempt crossed his face. “Say? Say what? There is no charge to answer. I know it and you know it. Frenchmen everywhere will -”

Jacaud plucked the sub-machine-gun from the hands of the sailor standing next to him, aimed quickly and fired a long burst that drove Bouvier back against the rail. He spun round, the material of his raincoat bursting into flame as bullets hammered across his back, and fell to the deck.

His wife cried his name once, took a single step forward and fainted, one of the passengers catching her as she fell backwards.

From the well-deck there was a strange, muted sigh from the crew and then there was only silence. Jacaud tossed the machine-gun to the sailor he had taken it from and went down the ladder without a backward glance. Fenelon looked as if he might be sick at any moment. He nodded to his men and hurriedly followed the big man, missing a step half-way down and almost falling to the deck.

They went over the side one by one and from the conning tower of the submarine the heavy machine-gun covered them menacingly. When they were all in the dinghy the sailors standing by the forward hatch hauled on the line quickly.

They left the dinghy to drift and everyone scrambled down through the hatch except Fenelon, who walked along the hull and climbed the ladder to the conning tower. He stood looking up at the freighter for a moment as the two vessels drifted apart, and on the Kontoro there was a strange, uncanny silence.

The two sailors dismounted the machine-gun and disappeared. Fenelon remained only a moment or two longer before following. The conning-tower hatch clanged shut, the sound echoing flatly across the water.

On the Kontoro it was as if a spell had been broken and everyone surged forward to the rail. Janvier had never felt quite so helpless in his life before and for some unaccountable reason was strangely close to tears.

In the distance the wind was already beginning to lift the waves into whitecaps and he remembered the gale warning. L’Alouette sank beneath the waves like a grey ghost, the tricolour waved bravely, then that too disappeared and there was only the sea.
