Jonas Merrick

In the office at MI5 where he works, they call Jonas Merrick 'the eternal flame'. It isn't a compliment. It's because he never goes out. He never goes undercover, never does surveillance, never goes with the teams that kick down the doors or seize the suspects off the street. He commutes into work and sits at his desk and then he goes home. But Jonas has qualities the hot-shots fail to notice: a steely concentration, a ruthless ability to focus and find the enemy hiding in plain sight.

Is the information they bring worth the cost of protecting them for the rest of their lives? Is it even genuine? Might they be double agents? These are some of the questions facing MI6 when a Russian agent hands himself in to them in Denmark. As a team begins to assess his value, his former employers in the Kremlin develop a brutal plan to show that no defector will ever be safe. And they know where to find him. Which means there must be a mole in MI6.

Liverpool: a suburban crime family grips a whole city with fear. And their ambition reaches further still. Galicia: an entire community waits on the windswept edge of Europe for the delivery of four tonnes of cocaine, brought across the ocean in an almost unbelievable craft. London: Jonas Merrick, grey and quiet, alone in a small office, seems an unlikely character to be tasked with bringing down an international drug network. But while Jonas's colleagues regard him as scratchy, fastidious, old, he is also ruthless, cunning and brutally pragmatic.

On the Mongolian steppes a general in the People's Liberation Army stakes his career, and his life, on a GPS-free missile guidance system that will change the balance of power on the battlefield. In Bath a young Chinese woman has secured the affections of a young brainiac working on that very problem. In Leamington Spa a deep cover operative has given himself away. And in London Jonas Merrick watches all, assessing, planning. A moment, perhaps, for him to strike a blow to China's espionage network in the UK. One thing he does not see, however, is in Moscow.

Jonas Merrick—a legendary intelligence analyst for MI5—has been banished to the Post Room of Thames House. There, he is expected to pass his remaining days before inevitable retirement. In a Russian gulag, an MI6 agent has developed an unlikely passion for a prisoner and has come up with an ingenious plan to free her. The key: a ruthless Albanian gang laundering the dirty money of the Russian elite. Merrick, the only agent with the experience to help, is brought back once again to intercept the Albanian courier until an exchange is organised by the Russians.
