A man dies on a crowded gangway. No cry, no struggle. Just a stranger's weight against Julian Vale's shoulder - and a split steel key pressed into his hand before the knees give way.
Vale has spent twenty years wounding systems that think they can't be touched. Now the Aegean's most dangerous secret has landed in his palm: half of a key to the Registry - the hidden machine that sells certainty about who really owns the fortunes moving through these islands. Whoever controls it can prove any lie true and any truth false.
To reach it, Vale needs the one man he should never trust: Adrian Kessler - a thief who studied Vale's own methods and turned them inside out. Where Vale wounds the powerful, Kessler sells them what they want. Their alliance is a marriage with a knife in it, and both of them know exactly where the knife is pointed.
Between them stands Nadia Sarris, a Piraeus fixer who has survived the docks by doing the smart trade every single time - until the night she doesn't.
From a rooftop chase above the Acropolis to a burning yacht off Mykonos, a siege in an abandoned marble quarry to a final reckoning in the ruins of a dead island, The Aegean Protocol drives toward a betrayal that will cost Vale everything - and leave him, for the first time in his invisible life, a man who can be found.
The Mediterranean Files return with the most personal, most explosive entry yet. Certainty, once wounded, does not heal. It only remembers.
Perfect for readers of Mark Dawson, Jack Carr, and Lee Child who like their thrillers lean, smart, and relentless.
