An American pioneer of the genre was Edmund Pearson, who was influenced in his style of writing about crime by De Quincey. Pearson published a series of books of this type starting with "Studies in Murder" in 1924 and concluding with "More Studies in Murder" in 1936. Before being collected in his books, Pearson's true crime stories typically appeared in magazines like "Liberty", "The New Yorker", and "Vanity Fair". Inclusion in these high-class magazines distinguished Pearson's crime narratives from those found in the penny press.
