Ian Fleming Publications Ltd has chosen international bestselling thriller writer, Jeffery Deaver, to write a new James Bond book. Regarding the book's title, Deaver added, "In the world of espionage, giving an agent carte blanche on a mission comes with an enormous amount of trust and constantly tests both personal and professional judgement. Part of the nonstop suspense in the novel is the looming question of what is acceptable in matters of national and international security. Are there lines that even James Bond should not cross?"
