Reveal a range of voices, narrative strategies, and fictional interests more wide-ranging and experimental than any other extant work of Hemingway’s In 1924 Ernest Hemingway published a small book of eighteen vignettes, each little more than one page long, with a small press in Paris. Titled in our time, the volume was later absorbed into Hemingway’s story collection In Our Time. Those vignettes, as Milton Cohen demonstrates in Hemingway’s Laboratory, reveal a range of voices, narrative strategies, and fictional interests more wide-ranging and experimental than any other extant work of Hemingway’s. Further, they provide a vivid view of his earliest tendencies and influences, first manifestations of the style that would become his hallmark, and daring departures into narrative forms that he would forever leave behind.
