and scurrying knew nothing of Luke, nor that she, Louisa Harris, was the happiest woman on earth.
She turned back toward the Boulevard, meaning to take a brisk walk all along the avenue of trees which makes a circuit round the inner part of the town and which ultimately would lead her back to the Gare du Nord and the Palace Hotel. It was a walk she had often done before: save for one or two busy corners on the way, it would be fairly solitary and peaceful.
Louisa stepped out with an honest British tread, hands buried in the pockets of her serviceable ulster, head bent against the sudden gusts of wind. She did not mind the darkness of the ill-lighted, wide boulevard, and had every intention of covering the two miles in a little more than half an hour.
How the time sped! It seemed as if she had only just left the hotel, and already surely not a quarter of a mile away she could see glimmering the lights of the Place Namur, the half-way point of her walk.
She was in the Boulevard Waterloo where private houses with closed porte-cochères add nothing to the municipal lighting of the thoroughfare.
Trams had been rushing past her in endless succession: but now there was a lull. Close by her a taxi-auto whizzed quickly past and came to a standstill some hundred yards away, near the pavement, and not far from an electric light standard.
Louisa, with vacant eyes attached on that cab, but with her mind fixed on a particular room in a particular house in Grosvenor Square where lived a man of the name of Luke de Mountford, continued her walk. Those same vacant eyes of hers presently saw the chauffeur of the taxi-auto get down from his box and open the door of the cab, and then her absent mind was suddenly brought back from Grosvenor Square, London, to the Boulevard Waterloo in Brussels, by a terrible cry of horror which had broken from that same chauffeur's lips. Instinctively Louisa hurried on, but, even as she did so, a small crowd which indeed seemed to have sprung from nowhere had already gathered round the vehicle.
Murmurs of "What is it? What is it?" mingled with smothered groans of terror, as curiosity caused one or two of the more bold to peer into the gloomy depths of the cab. Shrill calls brought a couple of gardiens to the spot. In a moment Louisa found herself a unit in an eager, anxious crowd, asking questions, conjecturing, wondering, horror-struck as soon as a plausible and graphic explanation came from those who were in the fore-front and were privileged to see.
"A man—murdered——"
"But how?"
"The chauffeur got down from his box . . . and looked in . . . ah, mon Dieu!"
"What did he see?"
"A man . . . he is quite young . . . only about twenty years of age."
"Stabbed through the neck——"
"Stabbed?—Bah?"
"Right through the neck I tell you . . . just below the ear. I can see the wound, quite small as if done with a skewer."
"Allons! Voyons! Voyons!" came the gruff accents from the two portly gardiens who worked vigorously with elbows and even feet to keep the crowd somewhat at bay.
Louisa was on the fringe of the crowd. She could see nothing of course—she did not wish to see that which the chauffeur saw when first he opened the door of his cab—but she stood rooted to the spot, feeling that strange, unexplainable fascination which one always feels, when one of those great life dramas of which one reads so often and so indifferently happens to be enacted within the close range of one's own perception.
She gleaned a phrase here and there—saw the horror-stricken faces of those who had seen, the placid, bovine expression of the two gardiens, more inured to such sights and calmly taking notes by the light of the electric standard.
"But to think that I drove that rascally murderer in my cab, and put him down safe and sound not ten minutes ago!" came with the adjunct of a loud oath from the irate chauffeur.
"How did it all occur?"
The gardiens tried to stem the flow of the driver's eloquence; such details should first be given to the police. Voyons! But what were two fat mouchards against twenty stalwart idlers all determined to hear—and then there were the women—they were determined to know more.
Louisa bent her ear to listen. She was just outside the crowd—not a part of it—and there was no really morbid curiosity in her. It was only the call of the imagination which is irresistible on these occasions—the prosy, matter-of-fact, high-bred girl could not, just then, tear herself away from that cab and the tragedy which had been enacted therein, in the mysterious darkness whilst the unconscious driver sped along, ignorant of the gruesome burden which he was dragging to its destination.
"Voila!" he was saying with many ejaculations and expletives, and a volley of excited gestures. "Outside the Parc near the theatre two bourgeois hailed me, and one of them told me to draw up at the top of the Galerie St. Hubert, which I did. The same one—the one who had told me where to go—got out, clapped the door to and spoke a few words to his friend who had remained inside."
"What did he say?"
"Oh! I couldn't hear and I didn't listen. But after that he told me to drive on to Boulevard Waterloo No. 34 and here I am."
"You suspected nothing?"
"Nothing, how should I? Two bourgeois get into my cab; I see nothing; I hear nothing. One of them gets out and tells me to drive on farther. How should I think there's anything wrong?"
"What was the other man like? The one who spoke to you?"
"Ma foi! I don't know. . . . It was raining so fast and pitch dark just outside the Parc lights—and he did seem to keep in the shadow—now I come to think of it—and his cap—he wore a cap—was pulled well over his face—and the collar of his coat was up to his nose. It was raining so, I didn't really see him properly. I saw the other one better—the one who has been murdered."
But the rotund gardiens had had enough of this. Moreover, they would hear all about it at full length presently. As for the crowd—it had no business to know too much.
They hustled the excited driver back on to his box, and themselves got into the cab beside it—the dead man, stabbed in the neck from ear to ear—the wound quite small as if it had been done with a skewer.
The gardiens ordered the chauffeur to drive to the commissariat, and Louisa turned away with a slight shiver down her spine and her throat choked with the horror of what she had only guessed.
CHAPTER II
ONCE MORE THE OBVIOUS
You don't suppose for a moment, I hope, that a girl like Louisa would allow her mind to dwell on such horrors. Mysterious crimes in strange cities—and in London, too, for a matter of that—are, alas! of far too frequent occurrence to be quite as startling as they should be.
A day or two later, Louisa Harris and her aunt, Lady Ryder, crossed over to England. They had spent five weeks in Italy and one in Brussels, not with a view to dreaming over the beauties of the Italian Lakes, or over the art treasures collected in the museums of Brussels, but because Lady Ryder had had a bronchial catarrh which she could not shake off and so her doctor had ordered her a thorough change. Bellaggio was selected, and Louisa accompanied her. They stayed at the best hotels both in Bellaggio and in Brussels, where Lady Ryder had several friends whom she wished to visit before she went home.
Nothing whatever happened that should not have happened; everything was orderly and well managed; the courier and the maid saw to tickets and to luggage, to hotel rooms and sleeping compartments. It was obviously their mission in life to see that nothing untoward or unexpected happened, but only the obvious.
It was clearly not their fault that Miss Harris had seen a cab in which
