"And the other man?" repeated Angus with a sort of obstinate quietude.
Laura Hope got to her feet suddenly. "My friend," she said, "I think you are a witch. Yes, you are quite right. I have not seen a line of the other man's writing; and I have no more notion than the dead of what or where he is. But it is of him that I am frightened. It is he who is all about my path. It is he who has half driven me mad. Indeed, I think he has driven me mad; for I have felt him where he could not have been, and I have heard his voice when he could not have spoken."
"Well, my dear," said the young man, cheerfully, "if he were Satan himself, he is done for now you have told somebody. One goes mad all alone, old girl. But when was it you fancied you felt and heard our squinting friend?"
"I heard James Welkin laugh as plainly as I hear you speak," said the girl, steadily. "There was nobody there, for I stood just outside the shop at the corner, and could see down both streets at once. I had forgotten how he laughed, though his laugh was as odd as his squint. I had not thought of him for nearly a year. But it's a solemn truth that a few seconds later the first letter came from his rival."
"Did you ever make the spectre speak or squeak, or anything?" asked Angus, with some interest.
Laura suddenly shuddered, and then said, with an unshaken voice, "Yes. Just when I had finished reading the second letter from Isidore Smythe announcing his success. Just then, I heard Welkin say, 'He shan't have you, though.' It was quite plain, as if he were in the room. It is awful, I think I must be mad."
"If you really were mad," said the young man, "you would think you must be sane. But certainly there seems to me to be something a little rum about this unseen gentleman. Two heads are better than one—I spare you allusions to any other organs and really, if you would allow me, as a sturdy, practical man, to bring back the wedding-cake out of the window—"
Even as he spoke, there was a sort of steely shriek in the street outside, and a small motor, driven at devilish speed, shot up to the door of the shop and stuck there. In the same flash of time a small man in a shiny top hat stood stamping in the outer room.
Angus, who had hitherto maintained hilarious ease from motives of mental hygiene, revealed the strain of his soul by striding abruptly out of the inner room and confronting the new-comer. A glance at him was quite sufficient to confirm the savage guesswork of a man in love. This very dapper but dwarfish figure, with the spike of black beard carried insolently forward, the clever unrestful eyes, the neat but very nervous fingers, could be none other than the man just described to him: Isidore Smythe, who made dolls out of banana skins and match-boxes; Isidore Smythe, who made millions out of undrinking butlers and unflirting housemaids of metal. For a moment the two men, instinctively understanding each other's air of possession, looked at each other with that curious cold generosity which is the soul of rivalry.
Mr. Smythe, however, made no allusion to the ultimate ground of their antagonism, but said simply and explosively, "Has Miss Hope seen that thing on the window?"
"On the window?" repeated the staring Angus.
"There's no time to explain other things," said the small millionaire shortly. "There's some tomfoolery going on here that has to be investigated."
He pointed his polished walking-stick at the window, recently depleted by the bridal preparations of Mr. Angus; and that gentleman was astonished to see along the front of the glass a long strip of paper pasted, which had certainly not been on the window when he looked through it some time before. Following the energetic Smythe outside into the street, he found that some yard and a half of stamp paper had been carefully gummed along the glass outside, and on this was written in straggly characters, "If you marry Smythe, he will die."
"Laura," said Angus, putting his big red head into the shop, "you're not mad."
"It's the writing of that fellow Welkin," said Smythe gruffly. "I haven't seen him for years, but he's always bothering me. Five times in the last fortnight he's had threatening letters left at my flat, and I can't even find out who leaves them, let alone if it is Welkin himself. The porter of the flats swears that no suspicious characters have been seen, and here he has pasted up a sort of dado on a public shop window, while the people in the shop—"
"Quite so," said Angus modestly, "while the people in the shop were having tea. Well, sir, I can assure you I appreciate your common sense in dealing so directly with the matter. We can talk about other things afterwards. The fellow cannot be very far off yet, for I swear there was no paper there when I went last to the window, ten or fifteen minutes ago. On the other hand, he's too far off to be chased, as we don't even know the direction. If you'll take my advice, Mr. Smythe, you'll put this at once in the hands of some energetic inquiry man, private rather than public. I know an extremely clever fellow, who has set up in business five minutes from here in your car. His name's Flambeau, and though his youth was a bit stormy, he's a strictly honest man now, and his brains are worth money. He lives in Lucknow Mansions, Hampstead."
"That is odd," said the little man, arching his black eyebrows. "I live, myself, in Himylaya Mansions, round the corner. Perhaps you might care to come with me; I can go to my rooms and sort out these queer Welkin documents, while you run round and get your friend the detective."
"You are very good," said Angus politely. "Well, the sooner we act the better."
Both men, with a queer kind of impromptu fairness, took the same sort of formal farewell of the lady, and both jumped into the brisk little car. As Smythe took the handles and they turned the great corner of the street, Angus was amused to see a gigantesque poster of "Smythe's Silent Service," with a picture of a huge headless iron doll, carrying a saucepan with the legend, "A Cook Who is Never Cross."
"I use them in my own flat," said the little black-bearded man, laughing, "partly for advertisements, and partly for real convenience. Honestly, and all above board, those big clockwork dolls of mine do bring your coals or claret or a timetable quicker than any live servants I've ever known, if you know which knob to press. But I'll never deny, between ourselves, that such servants have their disadvantages, too."
"Indeed?" said Angus; "is there something they can't do?"
"Yes," replied Smythe coolly; "they can't tell me who left those threatening letters at my flat."
The man's motor was small and swift like himself; in fact, like his domestic service, it was of his own invention. If he was an advertising quack, he was one who believed in his own wares. The sense of something tiny and flying was accentuated as they swept up long white curves of road in the dead but open daylight of evening. Soon the white curves came sharper and dizzier; they were upon ascending spirals, as they say in the modern religions. For, indeed, they were cresting a corner of London which is almost as precipitous as Edinburgh, if not quite so picturesque. Terrace rose above terrace, and the special tower of flats they sought, rose above them all to almost Egyptian height, gilt by the level sunset. The change, as they turned the corner and entered the crescent known as Himylaya Mansions, was as abrupt as the opening of a window; for they found that pile of flats sitting above London as above a green sea of slate. Opposite to the mansions, on the other side of the gravel crescent, was a bushy enclosure more like a steep hedge or dyke than a garden, and some way below that ran a strip of artificial water, a sort of canal, like the moat of that embowered fortress. As the car swept round the crescent it passed, at one corner, the stray stall of a man selling chestnuts; and right away at the other end of the curve, Angus could see a dim blue policeman
