Duncan Grant Books in Order

The Duncan Grant books follow an MI6 covert operative whose job is to hunt and, when necessary, kill on behalf of the British state. The series asks what happens to a man built for that work once he realises the people giving the orders are not always on the side of the angels.

In Kill Day, Grant survives a brutal ambush in the backstreets of Lyon that wipes out his surveillance team. Still carrying the raw instincts and discipline forged during a solitary upbringing on the Isle of Skye and in the toughest training MI6 can devise, he is thrown straight into the hunt for the assassin responsible. The search pulls him across borders, from the inner workings of British intelligence to the playgrounds of the ultra rich and the orbit of a powerful Saudi prince, as he discovers that elements within his own service are prepared to sell him out.

Grant is not a smooth superspy so much as a highly trained fighter who has to improvise as alliances shift around him. He wants to protect the innocent and clean up the mess, but every new revelation chips away at his faith in the institutions he serves, and in his own ability to stay on the right side of the line.

Dead Flags raises the scale. A series of near simultaneous assassinations sends the global intelligence community into panic. Grant realises the attacks bear the fingerprints of a charismatic arms dealer and mastermind he understands better than anyone. To stop a plot that could bring chaos to millions, he must dismantle a network of disavowed operatives and assassins spread across continents, and work alongside a mysterious deep cover agent whose loyalties are far from clear.

By The Last Albion, the past has come back with teeth. MI6 once ran Albion, a black programme that used a small cadre of elite assassins. Years later those former agents are living quiet, carefully constructed lives under new identities. Then someone starts murdering them. When Grant, already missing in action on a revenge mission of his own, is ordered to protect the last surviving Albion operative, he has to juggle his private hunt with an assignment that peels back layers of secrecy at the heart of the British establishment.

Across the trilogy, the Duncan Grant series delivers international locations, high stakes action, and intricate conspiracies. Underneath, it keeps circling the same questions: who gets to decide what is necessary, what loyalty costs, and whether a man like Grant can ever fully step out of the shadows he has been trained to inhabit.
