I am seeking the help of anyone who might be familiar with the works of David Graham Phillips, a muckraker. I have been conducting historical research on a relative, and have uncovered a 1921 story from the New York Times which states that this relative was "the original of the cook who, in a novel by David Graham Phillips, influenced legislation by her hash." The question here is: which novel contained a cook which influenced legislation?

I eagerly look forward to any replies. Many thanks to anyone knowledgeable enough to provide an answer to this.
