"The Red One" is a short story by Jack London first published in 1918 two years after his death. The story is told from the perspective of a scientist called Bassett, who is on an expedition in the jungle of Guadalcanal to collect butterflies. The "Red One" of the title refers to a giant red sphere, of apparently extraterrestrial origin, that the headhunting natives worship as their god and to which they perform human sacrifices. Bassett becomes obsessed with the Red One and in the end is sacrificed himself.
