At last the men began to go aboard. They were using a small boat which would hold only three men, and, as luck would have it, only the captain at length was left on the shore, talking to the “Italian” and Bernhard. The small boat, with only a single sailor in it, was being pulled ashore to fetch him when Jeans gave the single word “Fire!”
Our boat reeled slightly to the shock of the departing torpedo. At the range of a few hundred yards, under such circumstances, a miss was out of the question. A few seconds later a ponderous “boom!” blanketed by the waters, told us our torpedo had exploded and, gazing eagerly into the mirror of the periscope, I saw a blood-red flash as the enemy ship apparently flew to pieces in a confused column of spray and smoke. She must have been ripped open from end to end and, of course, disappeared instantly, with every soul on board.
“Now for the rest,” was Jeans’s laconic remark, as we swung out to the spot where we had put the landing-party ashore.
They were there almost as soon as we were, bringing with them the captain, Fontan, and the “Italian.” Dazed with the surprise and shock of the explosion, they had made no resistance to the rush of our men. The captain, indeed, had recovered himself sufficiently to throw into the sea a case of papers, but a sailor had dived and recovered it, and to our intense delight we found it gave details of the exact plans which had been made for the destruction of the Athabasca, with the precise points at which five successive U-boats were to lie in wait for her. This was luck indeed.
Soon we were on our way to intercept and destroy the first of the lurking Huns. Running at full speed on the surface, we kept our wireless busy, and soon had the satisfaction of knowing that our dispositions had been made to circumvent the enemy’s plots. Finally, nearing the scene of action, we submerged.
I need not here describe the tension of the hours which followed. Amid the steady hum of the machinery, Jeans was constantly busy, now scanning the surface of the sea through our periscope, now giving a watchful eye to every detail of the submarine’s complicated machinery.
At last, just as the first grey streaks of dawn showed on the horizon, he called me to the periscope, and, reflected in the mirror, I saw faintly the thin plume of smoke from the funnels of the approaching liner.
We knew that somewhere in that zone an enemy submarine lay awaiting her prey.
For half an hour we were keenly on the alert, as we watched the approaching liner. The captain had been warned by wireless, and we knew there would be no lack of watchfulness on board. We could imagine the gun-crew standing at their stations, every eye strained for the first sight of the enemy.
It came at last. Almost directly between us and the liner a German U-boat thrust her periscope out of the water and launched a torpedo. We saw the big liner swing suddenly to her swiftly ported helm, and we heard afterwards that, owing to her steersman’s promptness, the torpedo missed her bow by not more than a few feet.
Just as the liner turned the submarine broke water – why, I never could understand. Probably her commander was too supremely certain that his shot had gone home, or else some error in navigation had brought him to the surface earlier than he intended, for obviously it was his duty to remain submerged until he was sure his work was done.
Be that as it may, it was his last mistake. As the grey whale-back of the submarine rose above the water the gun of the Athabasca spoke. The first shot was over, the second short. Before the third was fired we had also bobbed up suddenly, and the U-boat found herself the target of two antagonists.
There could be only one end to such a fight. Almost simultaneously the third shot of the Athabasca and our first rang out, and both shells found their mark. One struck the conning-tower fair and square, blowing it clean away; the other crashed into the upper part of the hull, tearing a huge gap, and in a few seconds the enemy vessel had sunk with all hands, leaving only a flood of oil on the heaving surface of the sea to show where she had disappeared.
Next day I was on the Sud Express for Paris, while Madame Gabrielle, whom I had recalled by wire, followed me a few hours later.
From Hecq in Paris I learned the full sequel of our adventure. No news of the affair ever leaked out to the public. But it appears that, owing to the discovery of the plans from Kiel in possession of the submarine’s captain and our wireless messages, French destroyers and British submarines, operating together, had within twelve hours cleaned out the pirates’ nest, sinking four more submarines and taking nearly sixty prisoners, most of whom are now behind barbed wire in Wales.
Chapter Four
The Hidden Hand in Britain
“Ah! my dear Hecq – you have now set me a very difficult task – very difficult indeed!” I found myself saying a few weeks later, after I had mastered, with a good deal of trouble, a formidable dossier which had been laid before me by the astute chief of the French Secret Service, now promoted, by the way, to be chief of the International Secret Service Bureau of the Allies.
Though the time had been short since my return from Spain, much had happened. At length “unity of command” in contra-espionage work had been realised as an absolute essential for securing a definite mastery over the incessant plottings of the Huns, and, with the cordial goodwill of all, Armand Hecq – whose brilliant abilities had given him a commanding position – had been unanimously chosen for the much coveted post.
“I admit it is extremely difficult,” said the short, grey-bearded, alert little man, knocking the ash from his excellent cigar, leaning back in his cane deck-chair, and regarding me with an amused smile. “It is so difficult that I confess I do not see my way at all clearly. For that reason I have put the matter before you.”
“There can be no doubt about the seriousness of the affair,” I said. “The French Service have done very well so far, and so have our friends in London. We are quite well aware that during the past few weeks there has been an amazing recrudescence of German espionage, both here and in England, and even Whitehall is seriously alarmed. There is good reason for believing that working drawings of the new British trench-mortars have, by some means, been smuggled over to Germany. How they got out is a complete mystery, for the control at all the ports has been stricter than ever. Yet van Ekker has managed to get through to Holland a message from Berlin which leaves very little doubt as to the fact. It is undeniably serious, for the new mortar is a wonderful production, and I happen to know that it was intended to be one of the grand surprises in the Allies’ spring offensive.”
Hecq grunted, and I paused. Then I went on saying:
“We have a pretty good idea of the traitor in the department concerned, and he is now safely under lock and key. Unfortunately the mischief was done before he was even suspected, and the closest inquiries have failed to unearth any of his associates who would be regarded as in the slightest degree doubtful. It looks very much like a case of a hitherto thoroughly reliable man yielding to a sudden and overpowering temptation, while the real culprit – the man who pulled the strings – remains undiscovered. No doubt Count Wedell and his precious propaganda department have a first-class man at work, and they have so cleverly covered up the tracks that the method of their latest coup remains a mystery. It is perfectly obvious that the subterranean work of Germany is even now proceeding in France, Italy, and Great Britain.”
“Exactly, mon cher Sant. And you must take this particular matter in hand at once, and try to discover at least one of the fingers of what your good friends across the Channel call so appropriately ‘the Hidden Hand.’ For myself, I feel quite sure that at last, after much seeking, we have alighted on the source of the whole affair, so far as England and France are concerned.”
Our conversation had taken place at Armand Hecq’s house out at St. Germain, beyond Paris. I had come post-haste from Lausanne, where I had been engaged with Poiry – an ex-agent of the Paris Sûreté – upon another matter. An urgent telegram from Hecq had warned me that the new business was most important, hence I had lost no time in answering his summons.
It was a warm afternoon, and we were seated out on the terrace overlooking the pretty garden, which was the hobby of the most remarkable and resourceful secret agent in all Europe.
