Spy Sinker

 is the sixth novel in the Bernard Samson series, not counting the historical prequel Winter

As Len Deighton explained, it is the only book of the three trilogies not told from Bernard's point of view: 'Using third-person narrative, Spy Sinker ''starts in September 1977. It gives a wider and more complete story, and confides secrets that Bernard never knew. Focusing on Fiona Samson, it gives her version of the events that bring the story to that same summer of 1987 ' [Author's Note to Faith - his reference to 'that same' means his earlier mention of the first books in this trilogy, Spy Hook and Spy Line''].

Commentary
A Spy Hook, Spy Line and Spy Sinker (Trilogy) trilogy was published.
