Number 70, Berlin Part 15

As he walked in the falling twilight towards Pall Mall, he laughed lightly, muttering in German, beneath his breath: "That is their first taste of bombardment! They will have many yet, in the near future.

They laugh at our Zeppelins now. But will they laugh when our new aircraft bases are ready? No. The idiots, they will not laugh when we begin to drop bombs upon London!"

And, hailing a taxi, he entered it and drove home to Bruton Street, where Sir Boyle Huntley was awaiting him.

The man with the bloated, red face and loose lips greeted his friend warmly as he entered the quiet, cosy study. Then when Franks, Rodwell's man, had pulled down the blinds and retired, he exclaimed:

"Seen this evening's paper? Isn't it splendid, Lewin! All your doing, my dear fellow. You'll get a handsome reward for it. Trustram is very useful to us, after all."

"Yes," was the other's reply. "He's useful--but only up to a certain point. My only regret is that we haven't a real grip upon him. If we knew something against him--or if he'd borrowed money from one of our friends--then we might easily put on the screw, and learn a lot. As it is, he's careful to give away but little information, and that not always trustworthy."

"True," was Sir Boyle's reply. "But could we not manage to entice him into our fold? We've captured others, even more wary than he, remember."

"Ah! I wish I could see a way," replied Rodwell reflectively, as he stood before his own fireplace, his hands thrust deep into his trousers pockets.

"To my mind, Lewin, I foresee a danger," said the stout man, tossing his cigarette-end into the grate as he rose and stood before his friend.

"How?"

"Well--last night I happened to be at the theatre, and in the stalls in front of me sat Trustram with young Sainsbury, the fellow whom we dismissed from the Ochrida office."

"Sainsbury!" gasped the other. "Is he on friendly terms with Trustram, do you think?"

"I don't think, my dear fellow--I am certain," was the reply. "He had his girl with him, and all three were laughing and chatting merrily together."

"His girl? Let me see, we had him watched a few days ago, didn't we?

That's a girl living up at Hampstead--daughter of a Birmingham tool-manufacturer, Elise Shearman, isn't she?" remarked Rodwell slowly, his eyebrows narrowing as he spoke.

"I believe that was the name. Olsen watched and reported, didn't he?"

asked the Baronet.

"Yes. I must see him. That young fellow is dangerous to us, Boyle-- distinctly dangerous! He knows something, remember, and he would have told his friend Jerrold--if the latter had not conveniently died just before his visit to Wimpole Street."

"Yes. That was indeed a lucky incident--eh?"

"And now he is friendly with Charles Trustram. How did they meet, I wonder?"

"Trustram was, of course, a friend of Jerrold's."

"Ah--I see. Well, we must lose no time in acting," exclaimed Lewin Rodwell in a low, hard voice. "I quite realise the very grave and imminent danger. We may be already suspected by Trustram."

"Most probably, I think. We surely can't afford to court disaster any further."

"No," was Rodwell's low, decisive answer, and he drew a long breath.

"We must act--swiftly and effectively."

And then he lapsed into a long silence, during which his active brain was ardently at work in order to devise some subtle and deadly plan which should crush out suspicion and place them both in a position of further safety.

At the moment, the British public believed both men to be honest, patriotic supporters of the Government--men who were making much sacrifice for the country's welfare.

What if the horrible and disgraceful truth ever became revealed? What if they were proved to be traitors? Why, a London mob would undoubtedly lynch them both, and tear them limb from limb!

One man in England knew the truth--that was quite plain--and that man was young Sainsbury, the clerk who had accidentally overheard those indiscreet words in the boardroom in Gracechurch Street.

Lewin Rodwell, though ever since that afternoon when he had been so indiscreet he had tried to hide the truth from himself, now realised that, at all hazards, the young man's activity must be cut short, and his mouth closed.

Sir Boyle remained and dined with him. As a bachelor, and an epicure, Lewin Rodwell always gave excellent dinners, dinners that were renowned in London. He had a French _chef_ to whom he paid a big salary--a man who had been _chef_ at Armenonville, in the Bois, in Paris. Upon his kitchen Rodwell spared nothing, hence when any of those men--whom he afterwards so cleverly made use of to swell his bank-balance--accepted his hospitality they knew that the meal would be perhaps the best procurable in all London.

Many are the men-about-town who pride themselves upon their knowledge of the gastronomic art, and talk with loving reflections of the soups, entrees, and what-not, that they have eaten. Most of such men are what may be termed "hotel epicures." They swallow the dishes served at the fas.h.i.+onable hotels--dishes to the liking of their own palates possibly-- smack their lips, pay, and are satisfied. But the real epicure--and he is indeed a _rara avis_--is the one who knows that the thin-sliced grey truffle, light as a feather, cannot be put on a fillet in London, and that "sea-truffles" have never been seen in the Metropolis.

To be a real epicure one must be a cosmopolitan, taking one's _bouillabaisse_ in Ma.r.s.eilles, one's red mullet in Leghorn, one's caviare at eleven in the morning in Bucharest, one's smoked fish and cheese in Tromso, one's chicken's b.r.e.a.s.t.s with rice in Bologna, and so on, across the face of the earth. To the man who merely pretends to know, the long gilt-printed menu of the smart London hotel becomes enticing to the palate, but to the man who has eaten his dinner under many suns it is often an amusing piece of mysteriously-worded bunk.u.m.

Lewin Rodwell and his friend the Birthday Baronet sat down together to a perfectly-cooked and perfectly-served repast. Franks, the quiet, astute, clean-shaven man, a secret friend of Germany like his master, moved noiselessly, and the pair chatted without restraint, knowing well that Franks--whose real name was Grunhold--would say nothing. It was not to his advantage to say anything, because he was a secret agent of Germany of the fifth cla.s.s--namely, one in weekly receipt of sixty marks, or three pounds.

Rodwell was apprehensive, unhappy, and undecided. Truth to tell, he wanted to be alone, to plot and to scheme. His friend's presence prevented him from thinking. Yet, after dinner, he was compelled to go forth with him somewhere, so they went to the _revue_ at the Hippodrome, and on to Murray's afterwards.

It was half-past two o'clock in the morning when Rodwell re-entered with his latch-key and, pa.s.sing into his den, found upon his writing-table a rather soiled note, addressed in a somewhat uneducated hand, which had evidently been left during his absence.

Throwing off his overcoat, he took up the note and, tearing it open, read the few brief unsigned lines it contained. Then, replacing it upon the table, he drew his white hand across his brow, as though to clear his troubled brain.

Afterwards he crossed to the small safe let into the wall near the fireplace and, unlocking it, took forth a little well-worn memorandum-book bound in dark blue leather.

"Cipher Number 38, I think," he muttered to himself, as he turned over its pages until he came to that for which he was in search.

Then he sat down beneath the reading-lamp and carefully studied the page, which, ruled in parallel columns, displayed in the first column the alphabet, in the second the key-sentence of the cipher in question-- one of forty-three different combinations of letters--and in the third the discarded letters to be interspersed in the message in order to render any attempt at deciphering the more difficult.

In that cleverly-compiled little volume were forty-three different key-sentences, each easy of remembrance, and corresponding in its number of letters with about two-thirds, or so, of the number of letters of the alphabet. From time to time it changed automatically, according to the calendar and to a certain rule set forth at the end of the little volume. Hence, though the spy's code was constantly being changed without any correspondence from headquarters--"Number 70 Berlin"--yet, without a copy of the book, the exact change and its date could not be ascertained.

Truly, the very best brains of Germany had, long ago, been concentrated upon the complete system of espionage in Great Britain, with the result that the organisation was now absolutely perfect.

Taking a sheet of ruled paper from one of the compartments in the American rolltop desk before him, Lewin Rodwell, after leaning back wearily in his chair to compose himself, commenced, by reference to the pages of the little book before him, to trace out the cipher equivalents of the information contained in the note that had been left for him by an unknown hand in his absence.

He opened the big silver cigarette-box at his elbow, and having taken a cigarette, he lit it and began reducing the information into cipher, carefully producing a jumble of letters, a code so difficult that it had for a long time entirely defied the British War Office, the Admiralty, the Foreign Office, and the French Secret Service.

Though marvellously ingenious, yet it was, after all, quite simple when one knew the key-sentence.

Those key-sentences used by "Number 70 Berlin" in their wonderful and ever-changing secret code--that code by which signal lights were flashed across Great Britain by night, and buzzed out by wireless by day--were quite usual sentences, often proverbs in English, such as "A little knowledge is a dangerous thing," "A man and his money are soon parted,"

"Give one an inch and he'll take an ell," "Money makes the world go round," and so on.

Simple, of course. Yet the very simplicity of it all, combined with the constant change, const.i.tuted its greatest and most remarkable secrecy.

The great Steinhauer, with his far-reaching tentacles of espionage across both hemispheres, held his octopus-like grip upon the world, a surer, a more subtle and a more ingenious hold than the civilised world, from the spies of Alexander the Great down to those of President Kruger, had ever seen.

With infinite care, and because the information concerning certain naval movements in the Channel was urgent, he produced a ma.s.s of letters with words in German interspersed--a cipher message which resulted a fortnight later in one of our battles.h.i.+ps being sunk in the Channel, with only eighty survivors. Of the message the following is a facsimile:--

CHAPTER TWELVE.

ON THIN ICE.

One evening early in January three men had a.s.sembled and held a serious conference in Jack Sainsbury's modest little flat in Heath Street, Hampstead. His sister being out for the day, Jack had personally admitted his visitors, who were Charles Trustram and Sir Houston Bird, and the trio had sat by the fire discussing a matter of the greatest moment.
