Bernard Samson’s wife, Fiona, has just been chosen by the British Secret Service to be their top agent in Germany, set to undermine the East German economy. When she embarks on a violent, unparalleled mission of worldwide importance, it’s clear that there is only one way she can succeed. Fiona has always been a mystery to Samson—wife, mother, traitor, patriot, double agent—and now she is on the brink of betraying him. In the third novel in the brilliant Hook, Line, Sinker trilogy and the first in the series told in the third person, Len Deighton brings superspy Fiona Samson to center stage and asks: Who does Bernard really trust? And can we trust him?
