SOURCES: "The Shadow and the Flash" (1906)

DESCRIPTION: “Then they came together again, the impact of their blows, their groans and gasps, and the swift flashings and shadow-movings telling plainly of the deadliness of the struggle.” ("The Shadow and the Flash" by Jack London)

NOTES: The two rivals find two different ways to become invisible then fight it out to the death.

HISTORY: Jack London was not necessarily borrowing from H. G. Wells alone. Fitz-James O'Brien and Ambrose Bierce both used invisibility before Wells. The fact that London's invisible men are created scientifically suggests he was familair with Wells.
