Edgar Wallace (1875-1932) was a prolific British writer, whose life was as fascinating as his work. Born into poverty as Richard Horatio Edgar Wallace, he joined the army at age 21 and, from there, developed a love for writing. Starting as a war correspondent for Reuters and then for the Daily Mail, Wallace soon began to produce a vast array of novels, plays, and journalistic pieces. Known for his lightning-fast writing pace, he is often regarded as one of the masters of early 20th-century thrillers and crime novels. His literary style was characterized by brisk pacing, suspenseful storytelling, and an endearing touch of humor, which won him a wide readership. 'Killer Kay' demonstrates Wallace's knack for creating gripping narratives infused with action and mystery. Notably, Wallace is credited with nearly 200 novels, 18 stage plays, and 24 short story collections. His contributions to the detective genre were profound, particularly through the creation of the 'J. G. Reeder' and 'Sanders of the River' series. Despite facing financial difficulties throughout his life due to extravagant spending and gambling, Wallace left an indelible mark on the landscape of crime fiction. His works influenced not only his contemporaries but also the future generations of writers exploring the depths of mystery and crime.
