The Bourne Supremacy
trilogy – "The Bourne Identity" and "The Bourne Supremacy". The idea behind the Bourne trilogy came after he had a bout of temporary amnesia. After his first book, "The Scarlatti Inheritance", was published, he could not remember 12 hours of his life. This event, combined with thrilling real-life spy stories, inspired him to write the Jason Bourne trilogy.
