In that same interview, Uris was asked why he picked Ireland as a source of historical fiction.

It is the foundation upon which the book is built.' I have a sense of duty toward history, not to distort it and to keep within the framework of the basic truth' (Journal Exchange Company 2002).

Leon Uris died of heart failure June 21, 2003, at the age of 78, at his home on Shelter Island, New York. (For the extensive biographical overview of Leon Uris please see Exodus)
