The Inverted Pyramid by Bertrand W. Sinclair

Isabel Wall, the pert and pretty sister-in-law of Mr. Grove Norquay, became at last the cause of Rod's first definite breach in the fences.

When summer full-blown came tripping on the heels of spring, Rod left the Valdez camp for good. It had been a wholesome experience. One year in the woods had shown him quite fully the technique of big timber operations. It had shed an unreckoned light, moreover, upon the nature and mental processes of the men who handled the timber, which Rod was sure seldom appeared to the owners of the woods as a matter of any particular importance. He knew himself duly qualified as a practical logger. He was egotist enough to believe himself more capable of getting results without friction than most logging bosses. But he had not set out to qualify in timber so much as to get outside the shell of his class and see how and why man in general functioned both in and out of industry. He had covered the first phase that occurred to him. His own individual job, his book, began to nag him again, to assume form, proportion, to cry out for embodiment. So he laid aside calked boots and Mackinaws for canvas shoes and flannels, and took up the pleasant ways of Hawk's Nest when June brought the first coho salmon into the rapids and a chair in the shade was a comfortable thing.
