The Night Agent

A Russian mole at the highest levels of the White House drives Matthew Quirk's 2019 novel. By most accounts that is not the conspiracy the series chose to pursue. Viewers who know Peter Sutherland and Rose Larkin from the screen can meet them again in a story that is reportedly new to them, with its own conspiracy and possibly its own turns. The book is a compact, paperback-sized conspiracy thriller. It suits anyone who liked the show's premise of a midnight call and a junior agent pulled far out of his depth, and who wants to see where its original author took that idea.

The series keeps Matthew Quirk's premise and his two leads, Peter Sutherland and Rose Larkin, but, according to the available coverage, tells a different story built on the same starting point. The clearest reported divergence is the conspiracy itself. The novel centres on the hunt for a Russian mole at the highest levels of the White House, and sources describe the show as going in another direction, though the specifics of its version could not be confirmed. Whether the ending also changed is unknown, and comparison material was thin, so treat any finer differences as unverified.
