Is Richard Bachman a pseudonym, au was he real and Mr.King finished the manuscripts?

It is a pseudonym King used when he published Rage, The Long Walk , Roadwork , The Running Man and Thinner. The reason he did this is that at the time he wrote the "Rage" and "The Long Walk" he wasn't well known and had trouble publishing them. After he had become better known in the late 70's he decided to publish them, but his publisher suggested he use another name to prevent "overpublishing". After Bachman was discovered as a fake King came clean, but Bachman mashabiki were upset. Since the mystery surrounding the writer was so intriguing mashabiki just couldn't let go. So, King with his wonderful uandishi skills had finished his Richard Bachman bio (which included a stint in the marines and his tales of insomnia). To answer your swali about the manuscripts King had simply created the tale that the fictional Bachman's "widow" found manuscripts that were unpublished in his attic and after speaking with Bachman's editor agreed to have King finish the works. So, in short King created that story as a stunt for the disappointed Bachman fans.
