[Note: Sent in October of 1993, this letter to one of Martin's agents, Ralph Vicinanza, provides a glimpse of GRRM's original conception of the A Song of Ice and Fire series at the point where he had completed about a dozen chapters in A Game of Thrones. It is a very substantially different narrative than what eventually came to be published.]
[Note: The following interview is made available through the Internet Archive. The precise date, beyond April 1990, is unknown.]
