On holiday in The Gambia, Terry Bailey is enjoying his retirement from MI6 when he receives a shock. He spots a man in a car. It’s a fleeting glimpse. But it’s enough. He swears it is Jan the Dutchman, a drug overlord linked to a Colombian cartel. It can’t be Jan, as Jan is dead. Terry should know, he killed him.

Only one other person knows that Terry killed Jan – Michaela ‘Mike’ Kingdom, a CIA analyst based in London. Seven years ago, Jan had orchestrated the ambush in Holland that had killed Mike’s husband Dylan leaving her severely injured.

Was Terry tilting at windmills, Dutch windmills, or was Jan really alive seeking revenge? Terry tells Mike about the sighting and it re-opens wounds they both thought were long-healed.

It is now the beginning of a race to find Mike’s nemesis. But where to start? All Mike knew for certain is that he was not called Jan and he wasn’t a Dutchman. Apart from that, the search should be straightforward, shouldn’t it?
