In 1923, the young reporter James Thurber was given a half a page in the Sunday Evening Dispatch of Columbus, Ohio, every week to fill with anything he wanted. For most of that year, he turned out book reviews, humorous commentary, jokes, stories, and even literary criticism.He also wrote a series of 13 short Sherlockian parodies - 10,000 words in all - starring Blue Ploermell, a "psychosocial" detective with a fondness for animal crackers. Aided (and occasionally impeded) by his Chinese manservant, Gong Low, Ploermell investigates cases marked by his cock-eyed deductions, loopy logic, and knack for leaping to the wrong conclusion.These juvenilia represents Thurber's first attempts at learning the craft of humor writing. Looking back at this work years later, he even considered publishing the Ploermell stores. The Cases of Blue Ploermell, for the first time in a century, collects the 13 stories. Edited and annotated by Bill Peschel, they show Thurber trying his hand at characterization, story structure, ethnic humor, and serial writing in a style rarely seen at any newspaper.

In addition to the annotations, Peschel wrote essays on Thurber's years in Columbus, Ohio; journalism in the 1920s; the state of Sherlockian parodies; and depictions of Chinese men and women in American popular culture. Note: The 13 stories are very short, and take up 40 pages of this 200-page book. The rest of the book consists of these essays: "Becoming James Thurber" (39 pages); "Journalism in Thurber's Time" (4 pages); "Sherlockian Parodies in the 1920s" (8 pages); "The Ancestors of Gong Low" (13 pages); "The Chinese in Popular Culture" (35 pages); movie reviews (19 pages); chronology (9 pages); lists (7 pages).
