were alive with shop-girls and workers on their way home from business.
He smoked a cigarette and his interest was, perhaps, more apparent than real. He had attended his last surgery case and the door of the "shop," with its sage-green windows, had been locked for the night.
His eyes wandered idly to the Oxford Street end of the thoroughfare, and suddenly he started. A girl was walking toward him. At this hour there was very little wheeled traffic, for Lattice Street is almost a cul-de-sac, and she had taken the middle of the road. She was dressed with that effective neatness which brings the wealthy and the work-girl to a baffling level, in a blue serge costume of severe cut; a plain white linen coat-collar and a small hat, which covered, but did not hide, a mass of hair which, against the slanting sunlight at her back, lent the illusion of a golden nimbus about her head.
The eyes were deep-set and wise with the wisdom which is found alike in those who have suffered and those who have watched suffering. The nose was straight, the lips scarlet and full. You might catalogue every feature of Oliva Cresswell and yet arrive at no satisfactory explanation for her charm.
Not in the clear ivory pallor of complexion did her charm lie. Nor in the trim figure with its promising lines, nor in the poise of head nor pride of carriage, nor in the ready laughter that came to those quiet eyes. In no one particular quality of attraction did she excel. Rather was her charm the charm of the perfect agglomeration of all those characteristics which men find alluring and challenging.
She raised her hand with a free unaffected gesture, and greeted the doctor with a flashing smile.
"Well, Miss Cresswell, I haven't seen you for quite a long time."
"Two days," she said solemnly, "but I suppose doctors who know all the secrets of nature have some very special drug to sustain them in trials like that."
"Don't be unkind to the profession," he laughed, "and don't be sarcastic, to one so young. By the way, I have never asked you did you get your flat changed?"
She shook her head and frowned.
"Miss Millit says she cannot move me."
"Abominable," he said, and was annoyed. "Did you tell her about Beale?"
She nodded vigorously.
"I said to her, says I," she had a trick of mimicry and dropped easily into the southern English accent, "'Miss Millit, are you aware that the gentleman who lives opposite to me has been, to my knowledge, consistently drunk for two months—ever since he came to live at Kroomans?' 'Does he annoy you?' says she. 'Drunken people always annoy me,' says I. 'Mr. Beale arrives home every evening in a condition which I can only describe as deplorable.'"
"What did she say?"
The girl made a little grimace and became serious.
"She said if he did not speak to me or interfere with me or frighten me it was none of my business, or something to that effect." She laughed helplessly. "Really, the flat is so wonderful and so cheap that one cannot afford to get out—you don't know how grateful I am to you, doctor, for having got diggings here at all—Miss Millit isn't keen on single young ladies."
She sniffed and laughed.
"Why do you laugh?" he asked.
"I was thinking how queerly you and I met."
The circumstances of their meeting had indeed been curious. She was employed as a cashier at one of the great West End stores. He had made some sort of purchase and made payment in a five-pound note which had proved to be counterfeit. It was a sad moment for the girl when the forgery was discovered, for she had to make up the loss from her own pocket and that was no small matter.
Then the miracle had happened. The doctor had arrived full of apologies, had presented his card and explained. The note was one which he had been keeping as a curiosity. It has been passed on him and was such an excellent specimen that he intended having it framed but it had got mixed up with his other money.
"You started by being the villain of the piece and ended by being my good fairy," she said. "I should never have known there was a vacancy here but for you. I should not have been admitted by the proper Miss Millit but for the terror of your name."
She dropped her little hand lightly on his shoulder. It was a gesture of good-comradeship.
She half-turned to go when an angry exclamation held her.
"What is it? Oh, I see—No. 4!"
She drew a little closer to the doctor's side and watched with narrowing lids the approaching figure.
"Why does he do it—oh, why does he do it?" she demanded impatiently. "How can a man be so weak, so wretchedly weak? There's nothing justifies that!"
"That" was apparently trying to walk the opposite kerb as though it were a tight-rope. Save for a certain disorder of attire, a protruding necktie and a muddy hat, he was respectable enough. He was young and, under other conditions, passably good looking. But with his fair hair streaming over his forehead and his hat at the back of his head he lacked fascination. His attempt, aided by a walking-stick used as a balancing-pole, to keep his equilibrium on six inches of kerbing, might have been funny to a less sensitive soul than Oliva's.
He slipped, recovered himself with a little whoop, slipped again, and finally gave up the attempt, crossing the road to his home.
He recognized the doctor with a flourish of his hat.
"Glorious weather, my Escu-escu-lapius," he said, with a little slur in his voice but a merry smile in his eye; "simply wonderful weather for bacteria trypanosomes (got it) an' all the jolly little microbes."
He smiled at the doctor blandly, ignoring the other's significant glance at the girl, who had drawn back so that she might not find herself included in the conversation.
"I'm goin' to leave you, doctor," he went on, "goin' top floor, away from the evil smells of science an' fatal lure of beauty. Top floor jolly stiff climb when a fellow's all lit up like the Hotel Doodledum—per arduis ad astra—through labour to the stars—fine motto. Flying Corps' motto—my motto. Goo' night!"
Off came his hat again and he staggered up the broad stone stairs and disappeared round a turn. Later they heard his door slam.
"Awful—and yet–"
"And yet?" echoed the doctor.
"I thought he was funny. I nearly laughed. But how terrible! He's so young and he has had a decent education."
She shook her head sadly.
Presently she took leave of the doctor and made her way upstairs. Three doors opened from the landing. Numbers 4, 6 and 8.
She glanced a little apprehensively at No. 4 as she passed, but there was no sound or sign of the reveller, and she passed into No. 6 and closed the door.
The accommodation consisted of two rooms, a bed-and a sitting-room, a bath-room and a tiny kitchen. The rent was remarkably low, less than a quarter of her weekly earnings, and she managed to live comfortably.
She lit the gas-stove and put on the kettle and began to lay the table. There was a "tin of something" in the diminutive pantry, a small loaf and a jug of milk, a tomato or two and a bottle of dressing—the high tea to which she sat down (a little flushed of the face and quite happy) was seasoned with content. She thought of the doctor and accounted herself lucky to have so good a friend. He was so sensible, there was no "nonsense" about him. He never tried to hold her hand as the stupid buyers did, nor make clumsy attempts to kiss her as one of the partners had done.
The doctor was different from them all. She could not imagine him sitting by the side of a girl in a bus pressing her foot with his, or accosting her in the street with a "Haven't we met before?"
She ate her meal slowly, reading the evening newspaper and dreaming at intervals. It was dusk when she had finished and she switched on the electric light. There was a shilling-in-the-slot meter in the bath-room that acted eccentrically. Sometimes one shilling would supply light for a week, at other times after two days the lights would flicker spasmodically and expire.
She remembered that it was a perilous long time since she had bribed
