Les Enfants Terribles is a 1929 novel by Jean Cocteau, published by Editions Bernard Grasset. It concerns two siblings, Elisabeth and Paul, who isolate themselves from the world as they grow up, an isolation which is shattered by the stresses of their adolescence. It was first translated into English by Samuel Putnam in 1930 and published by Brewer & Warren. A later English translation by Rosamond Lehmann was published in the U.S. by New Directions (ISBN 0811200213) in 1955, and in Canada by Mclelland & Stewart in 1966, with the title translated as The Holy Terrors. The book is illustrated by the author's own drawings. The novel was made into a film of the same name, a collaboration between Cocteau and director Jean-Pierre Melville, in 1950, and inspired the opera of the same name by Philip Glass. The ballet La Boule de neige by the choreographer Fabrizio Monteverde, with music by Pierluigi Castellano, is also based on this novel. The story was adapted by the writer Gilbert Adair for his 1988 novel The Holy Innocents, which was the basis for Bernardo Bertolucci's 2003 film The Dreamers. Source: Wikipedia (en)
