John Minute, formerly an unscrupulous African mining magnate, has flown to England, but can't escape his past. Constantly threatened by blackmailers, he fears death and financial ruin. At the suggestion of the commissioner of police, "The Man Who Knows" is hired to assist in determining the source of these threats. But after John is murdered, suspicion is cast on his nephew, who calls on The Man Who Knows to help clear his name and cast suspicion on Jasper Cole, John's loyal secretary. The trail to the real murderer presents a formidable challenge—even to The Man Who Knows. Published in 1918, The Man Who Knew was adapted for film in 1961. Edgar Wallace (died 1932) was a major literary figure of the early 20th century. Their work has endured across generations and continues to be read and studied worldwide. Adventure literature of the 19th and early 20th centuries captured the imagination of a reading public hungry for tales of exploration, danger, and heroism. The Man Who Knew belongs to this tradition of gripping narratives that transported readers beyond the boundaries of their everyday lives.
