Harry Stephen Keeler wrote more than seventy novels throughout his career and met with success in several countries, including Spain, Portugal, Great Britain, and the United States. His principal contribution to the mystery and detective genre is his bizarre “webwork novel,” in which outlandish, melodramatic plots, subplots, and sub-subplots are piled atop one another. These intricate “webbings” grow into a dizzying pyramid of coincidences and interlocking connections—a plot that threatens to topple but that Keeler skillfully resolves. Keeler’s mastery of plot has elicited awe and admiration from his loyal admirers. He is also known for his uncanny ability to mix humor and horror to stunning effect.
