Finally she leaned back in her chair, twisting her wrist for a glimpse of her watch. Whew! Half past twelve, and she was to meet her sister Margaret for luncheon. She stood a moment at the window. Beyond the neighboring buildings the spires of the Cathedral splintered the sunlight; a flock of pigeons whirled into view, their wings flashing in the light, then darkening as they swirled and vanished—like the cadence of a verse, thought Catherine. Far beneath her lay an angle of the Avenue, with patches of shining automobile tops crawling in opposing streams.

She gave a great sigh as she turned back to the office. A long, narrow room, scarcely wider than the window, lined with shelves ceiling-high, between them the flat desk piled with her work. Her work! Almost a week of it, now, and already she had won back her old ability to draw that thin, sliding wall of steel across her personal life, to hold herself contained within this room and its contents.

She hadn't seen Margaret since her return from Maine. She was to meet her at the St. Francis Luncheon Club for Working Women. As she stepped into the sunlight of the street, the slow flowing of the emulsion of which she was suddenly another particle, she had a sharp flash of unreality. Was it she, walking there in her old blue suit, her rubber heels padding with the other sounds, her eyes refocusing on distance and color after the long morning? She loved the long, narrow channel of the Avenue, hard, kaleidoscopic; the white clouds above the line of buildings, the background of vivid window displays. She laughed softly as she recalled the early days of the week. Rainy, to begin with. She had thought, despairingly, that she couldn't swing the job. The children stood between her and the sheets of paper. She had flown out at noon to telephone Miss Kelly, to demand assurance that life in the apartment hadn't gone awry in the four hours since she had left. Queer. You seized your own bootstraps and lugged, apparently in vain, to lift yourself from your habits of life, of thought, of constant concern, and then, suddenly, you had done it, just when you most despaired. She walked with a graceful, long stride, her head high. An excellent scheme, Dr. Roberts had said. He had really entrusted her with the entire plan for this investigation. And she could do it!

Margaret was waiting at the elevator entrance, a vivid figure in the milling groups of befurbished stenographers and shoddier older women. She came toward Catherine, and their hands clung for a moment. How young she is, and invincible, thought Catherine, as they waited for the elevator to empty its load. Margaret had Catherine's slimness and erect height; her bright hair curled under the brim of her soft green hat; there was something inimitably swagger about the lines of her sage-green wool dress and loose coat, with flashes of orange in embroidery and lining. In place of the sensitive poise of Catherine's eyes and mouth, Margaret had a downright steadiness, an untroubled intensity.

"How's it feel to be a wage-earner?" She hugged Catherine's arm as they backed out of the pushing crowd into a corner of the car. "You look elegant!"

"Scarcely that." Catherine smiled at her. "Now you do! Did you design that color scheme?"

"I matched my best points, eyes and high lights of hair." Margaret grinned. Her eyes were green in the shadow. "Ever lunched here? I thought you might find it convenient. Lots of my girls come here."

They emerged at the entrance of a large room full of the clatter of dishes and tongues.

"I'll take you in on my card to-day. If you like it, you can get one." Margaret ushered Catherine into the tail of the line which filed slowly ahead of them. "This is one of the gracious ladies—" Margaret shot the half whisper over her shoulder, as she extended her green card. "A guest, please." Catherine looked curiously at the woman behind the small table; her nod in response to the professionally sweet smile was curt.
