The Lisbon Exchange #1 in the Marcus Vane Series

Some mornings the war never ends.

For fourteen months, Marcus Vane has been a fisherman in a Greek village above a quiet gulf — drinking coffee at the same kafeneion, reading Cavafy, learning slowly how to be a man who is no longer at war. Then, on a Tuesday in late September, a black Audi parks under the lime trees outside the harbour. By mid-morning he is at a payphone in Preveza, dialling a London number he has not dialled in over a year.

Thomas Greer is dead. Sixty-seven years old. Car off the Brenner Pass at four in the morning. His wedding ring missing.

The Austrians are calling it ice.

MI6 isn't.

For eight months, Greer — counter-intelligence chief, and the man who recruited Marcus at Oxford twenty-two years earlier — had been quietly running a parallel investigation into a mole inside the Service. A traitor who has compromised four operations across six years. A traitor who has now killed to protect himself.

Greer had narrowed his suspects to four. He never wrote the names down.

Marcus has weeks, perhaps days, before the architecture of betrayal closes around him. From a windowless storage cupboard in Vauxhall Cross to a coffee house in Vienna's Eighth District, from a Roman restaurant in plain view of a Russian handler to a salt-edged cottage on the Dorset coast, he follows the money, the corridor glances, the small specific lies. He works against a clock he cannot quite see. He works against the conviction that the man who killed Thomas Greer is, right now, somewhere on the upper floors of his own building, having coffee.

What he uncovers is not a single betrayal but the patient architecture of something much larger — and the discovery will cost him more than he is ready to pay.

For readers of John le Carré, Mick Herron, Charles Cumming, and Daniel Silva. The Lisbon Exchange is a literary spy thriller in the great British tradition: slow-burning, character-driven, devastatingly precise. It is the first novel in the Marcus Vane series.

Some betrayals don't end. They only wait.
