“The Norfolk Mystery,” as it was termed by the sensational journalists and Press-photographers, was but a nine days’ wonder, as, indeed, is every modern murder mystery.

It provided material for the sensational section of the Press for a full week; a hundred theories were advanced, and the police started out upon a dozen or more false scents, but all to no purpose. Therefore the public curiosity quickly died down, and within ten days or so the affair was forgotten amid the hundred and one other “sensations” of crime and politics, of war rumours, and financial booms, which hourly follow upon each other’s heels and which combine to make up the strenuous unrest of our daily life.

And so was the fatal accident to the naval aviator quickly forgotten by the public.

Many readers of these present lines no doubt saw reports of both affairs in the papers, but few, I expect, will recollect the actual facts, or if they do, they little dream of the remarkable romance of life of which those two unexplained tragedies formed the prologue.

On the night when the coroner’s jury returned in the case of Richard Harborne a verdict of “Wilful murder by some person unknown,” a girl sat in her small, plainly-furnished bedroom on the top floor of a house in New Oxford Street, in London, holding the evening paper in her thin, nerveless fingers.

It was Jean Libert.

She had been reading an account of the evidence given at the inquest, devouring it eagerly, with pale face and bated breath. And as she read her chest rose and fell quickly, her dark eyes were filled with horror, and her lips were ashen grey. The light had faded from her pretty face, her cheeks were sunken, her face haggard and drawn, and about her mouth were hard lines, an expression of bitter grief, remorse, despair.

A quarter of an hour ago, while in the small, cheap French restaurant below, kept by her father—a long, narrow place with red-plush seats along the white walls and small tables set before them—an urchin had passed, selling the “extra special.” On the contents bill he carried in front of him were the words, in bold type: “Norfolk Mystery—Verdict.”

She had rushed out into the street, bought a paper, and hastily concealing it, had ascended to her room, and there locked herself in.

Then she sank upon her bed and read it. Three times had she carefully read every word, for the report was a rather full one. Afterwards she sat, the paper still in her white hand, staring straight at the old mahogany chest of drawers before her.

“Poor Dick!” she murmured. “Ah! Heaven! Who could have done it? Why—why was he killed on that evening? If he had not gone to Mundesley to meet me he would not have lost his life. And yet——”

She paused, startled at the sound of her own voice, so nervous had she now become.

She glanced at the mirror, and started at sight of her own white, drawn countenance.

She placed both hands upon her eyes, as though striving to recall something, and in that position she remained, bent and pensive, for some moments.

Her lips moved at last.

“I wonder,” she exclaimed, very faintly, speaking to herself, “I wonder whether Ralph will ever know that I met Dick? Ah! yes,” she sighed; “I was foolish—mad—to dare to go to Mundesley that afternoon. If only I could have foreseen the consequence of our secret meeting—ah! if only I had known what I know now!”

Again she was silent, her face pale, with a fixed, intense look, when at last she rose, unlocked one of the small top drawers of the chest, and, taking the drawer entirely out, extracted something that had been concealed beneath it.

She held it in her hand. There were two halves of one of Dick Harborne’s visiting-cards—signed and torn across in a similar manner to those pieces which had been handed for the coroner’s inspection. Each half bore a number on its back, while on the front, as she placed them together, was Harborne’s name, both printed and written.

For a long time she had her eyes fixed upon it. Her brows narrowed, and in her eyes showed a distinct expression of terror.

“Yes,” she whispered; “I was a fool—a great fool to have dared so much—to have listened, and to have consented to go across to Bremen. But no one knows, except Dick—and he, alas!—he’s dead! Therefore who can possibly know?—no one.”

She held the halves of the torn card between her fingers for some moments, looking at them. Then, sighing deeply, she rose with sudden impulse and, crossing the room, took up a box of matches. Striking one, she applied it to the corners of the half cards and held the latter until the blue flame crept upwards and consumed them.

Then she cast them from her into the grate.

It was the end of her romance with that man who had been struck that cowardly blow in secret—Richard Harborne.

She stood gazing upon the tiny piece of tinder in the fender, immovable as a statue. Her dark brows slowly narrowed, her white, even teeth were set, her small hands clenched, as, beneath her breath, she uttered a fierce vow—a hard, bitter vow of vengeance.

Before her arose the vision of her good-looking lover, the man with the dark, intense eyes—Ralph Ansell. And then the memory of the dead Dick Harborne instantly faded from her mind.

Her romance with Dick had been but a passing fancy. She had never really loved him. Indeed, he had never spoken to her of love. Yet he had fascinated her, and in his presence she had found herself impelled by his charm and his easy-going cosmopolitanism, so that she had listened to him and obeyed, even against her own will.

She recollected vividly that adventurous journey to Bremen—recalled it all as some half-forgotten, misty dream. She could feel now the crisp crackling of those Bank of England notes which she had carried secreted in her cheap little dressing-case with its electro-plated fittings. She remembered, too, the face of the stranger, the fat, sandy-haired German, whom she had met by appointment upon a flat country road a mile distant from the city towards Ottersberg—how he had given her, as credential, one of those pieces of visiting-card, together with a bulky letter, and how, in return, she had handed him the English bank-notes.

Then there was the mysterious packet she had subsequently given to Dick, when she had met him one evening and dined with him at the Trocadero. Then he had thanked her, and declared his great indebtedness.

From that night, until the day of the tragedy, she had not seen him. Indeed, she had made up her mind never to do so. Yet he had persuaded her to meet him at Mundesley, and she had consented, even though she knew what risk of detection by Ralph she must run.

Was it possible that Ralph knew?

The thought held her breathless.

Ralph Ansell loved her. He had sworn many times that no other man should love her. What if Dick’s death had been due to Ralph’s fierce jealousy!

The very suspicion staggered her.

Again she sank upon her little white bed, gripping the coverlet in her nervous fingers and burying her face in the pillow.

She examined her own heart, analysing her feelings as only a woman can analyse them.

Yes. She loved Ralph Ansell—loved him sincerely and well. Eighteen months ago he had casually entered the little restaurant one evening and ordered some supper from Pierre, the shabby, bald-headed waiter, who had been for so many years in her father’s service. At that moment Jean—who was employed in the daytime at the Maison Collette, the well-known milliners in Conduit Street—happened to be in the cash-desk of her father’s little establishment where one-and-sixpenny four-course luncheons and two-shilling six-course dinners were served.

From behind the brass grille she had gazed out upon the lonely, good-looking, well-dressed young fellow whom she saw was very nervous and agitated. Their eyes met, when he had instantly become calm, and had smiled at her.

He came the next night and the next, with eyes only for her, until he summed up courage to speak to her, with the result that they had become acquainted.

A young man of French birth, though his father had been an American domiciled in Paris, he was possessed of independent means, and lived in a cosy little bachelor flat half-way up Shaftesbury Avenue on the right-hand side. Far more French than English, in spite of his English name, he quickly introduced himself into the good graces of Jean’s father—the short, dapper old restaurateur, Louis Libert, a ProvenÇal from the remote little town of Aix, a Frenchman whom many years’ residence in London had failed to anglicise.

For nearly twenty years old Louis Libert had kept the Restaurant Provence, in Oxford Street, yet Mme. Libert, on account of the English climate, had preferred to live with her mother in Paris, and for fully half the period had had her daughter Jean with her. In consequence, Jean, though she spoke English well, was, nevertheless, a true Parisienne.

Since her mother’s death, four years previously, she had lived in London, and was at present engaged as modiste at the Maison Collette, where many of the “creations” of that world-famous house were due to her own artistic taste and originality.

At first, her father had looked askance at the well-dressed young stranger who so constantly had dinner or supper at the restaurant, but ere long, in consequence of secret inquiries he had made of the hall porter of the flats in Shaftesbury Avenue, he had accepted the young man, and had even been gratified by the proposal of marriage which Ralph had placed before him.

Thus the pair had become engaged, the wedding being fixed to take place in the middle of November. Even as Jean stood there, a faint tap was heard at the door, and the maid-of-all-work announced:

“Mr. Ansell is downstairs, miss.”

Jean responded, and after washing her hands and patting her hair before the glass, put on her hat and descended to the rather dingy, old-fashioned drawing-room over the shop, where stood her lover alone at the open window, looking down upon the traffic in the broad, brilliantly-lit London thoroughfare.

Very neat and dainty she looked in her well-cut, dark skirt, and blouse of white crÊpe de Chine, which she wore with a distinctly foreign chic, and as she entered, her pretty face was bright and happy: different, indeed, to the heavy, troubled expression upon it ten minutes before.

“Ah, Ralph!” she cried, in warm welcome, as she sprang into his ready arms, and he bent till his lips touched hers. “You are earlier than you expected,” she added in French. “I hardly thought you would be able to get back from the country in time to-night.”

“Well, you see, dearest, I made an effort, and here I am,” replied the young man with the strong, clean-shaven features and the large, round, penetrating eyes. “I’ve been travelling ever since three o’clock, and it’s now nearly ten.”

Though he, too, spoke in French, his appearance was very English. No one would have taken him for anything else but an honest, upright, thorough-going young Englishman. He was of that strong, manly, well-set-up type, the kind of level-headed, steady young man, with whom no father would hesitate to entrust his daughter’s future. As he stood in his smart, blue serge suit with well-ironed trousers, and a fine diamond in his cravat, holding her in his arms and kissing her fondly, he looked the true lover, and assuredly their hearts beat in unison.

Jean Libert loved him with a great, all-consuming affection, a blind passion which obliterated any defects which she might have observed, and which endowed him in her eyes with all the qualities of a hero of romance.

They were, indeed, a handsome pair. Her dark head was resting upon his shoulder, while his strong right arm was about her slim waist.

Since her return, three days ago, from her summer holiday by the sea at Cromer they had not met. That morning, being Monday, she had resumed her daily labours in the big, long workroom of the Jewish firm who traded under the name of the Maison Collette, and she had, as is usual with girls, related to her friends many of the incidents of what she declared to be “a ripping holiday.”

As she stood with her white hand tenderly upon his shoulder, looking lovingly into his eyes, she was describing her return to business, and how she regretted that the long summer seaside days were no more, whereupon he said, cheerfully, in English:

“Never mind, darling; November will soon come, and you will then have no further need to go to business. You will be mine. Shall we go out for a walk?” he suggested, noticing that she already had her hat on.

To his suggestion she willingly assented, and, raising her full, red lips to his, she kissed him, and then they descended to the restaurant below, empty at that hour save for the seedy old waiter, Pierre, and her father, an elderly, grey, sad-looking man, whose business in later years had, alas! sadly declined on account of the many restaurants which had sprung up along Oxford Street during the past ten years. He had seen better times, but nowadays it was always a hard struggle to make both ends meet, to pay the landlord and to live.

Ralph and old Libert exchanged greetings in French, and then, with Jean upon his arm, young Ansell stepped out into Oxford Street.

The August night was dry, warm, and starlit. Few people were about as they strolled along, chatting and laughing merrily. Before the theatres discharge their chattering crowds, the main thoroughfares of central London are usually quiet and half-deserted, and as the pair walked in the direction of Regent Street, Jean’s heart beat gladly with supreme satisfaction that at last Ralph had returned to London.

November! Far off seemed that day of all days in her life when she would be Ralph’s bride.

Upon her finger was the engagement ring he had given her, one set with diamonds of such fine quality that old Libert had wondered. Indeed, a jeweller, whose habit it was to take his luncheon there each day, had noticed it upon Jean’s finger, and had valued it roughly at a hundred pounds. Therefore Ralph could certainly not be badly off!

They had turned the corner into Regent Street, but were too engrossed in each other’s conversation to notice that, in passing, a tall, grey-faced man, who wore a crush-hat, with a black coat over his evening clothes, had suddenly recognised Ansell.

For a few steps he strode on with apparent unconcern, then he paused and, having gazed for several moments after them still walking with linked arms, unconscious of being remarked, he turned on his heel, crossed the road, and strolled in the direction they were walking.

The watcher was the same grey-faced, keen-looking stranger who, earlier that day, had sat in the country schoolroom at North Walsham listening to the evidence given before the coroner concerning the mystery of the Norwich Road.

His thin lips curled in a smile—a smile of bitter triumph—as he went on with crafty footsteps behind the pair, watching them from across the road.
