Edna Ferber 
Emma McChesney and Co. [EPUB ebook] 

BROADWAY TO BUENOS AIRES
The door marked "MRS. MCCHESNEY" was closed. T. A. Buck, president of the Buck Featherloom Petticoat Company, coming gaily down the hall, stopped before it, dismayed, as one who, with a spicy bit of news at his tongue's end, is met with rebuff before the first syllable is voiced. That closed door meant: "Busy. Keep out."
"She'll be reading a letter, " T. A. Buck told himself grimly. Then he turned the knob and entered his partner's office.
Mrs. Emma Mc Chesney was reading a letter. More than that, she was poring over it so that, at the interruption, she glanced up in a maddeningly half-cocked manner which conveyed the impression that, while her physical eye beheld the intruder, her mental eye was still on the letter.
"I knew it, " said T. A. Buck morosely.
Emma Mc Chesney put down the letter and smiled.
"Sit down—now that you're in. And if you expect me to say, 'Knew what?' you're doomed to disappointment."
