Rikki-Tikki-Tavi  is a short story in the 1894 anthology
The Jungle Book
by Rudyard Kipling about adventures of a valiant young Indian grey mongoose. It has often been anthologised, and has been published several times as a short book.
The Book 5 of Panchatantra , an ancient Indian collection, includes the mongoose and snake story, an inspiration for the ‘Rikki-Tikki-Tavi’ story.
Joseph Rudyard Kipling (30 December 1865 – 18 January 1936) was an English journalist, short-story writer, poet, and novelist. He was born in India, which inspired much of his work. Kipling’s works of fiction include The Jungle Book (1894), Kim (1901), and many short stories, including ‘The Man Who Would Be King’ (1888). His poems include ‘Mandalay’ (1890), ‘Gunga Din’ (1890), ‘The Gods of the Copybook Headings’ (1919), ‘The White Man’s Burden’ (1899), and ‘If—’ (1910). He is seen as an innovator in the art of the short story. His children’s books are classics; one critic noted ‘a versatile and luminous narrative gift.’
