It is the summer of 1961 and the brutal Cold War between East and West is becoming ever more perilous.

Two young prodigies from either side of the Iron Curtain, Yulia and Michael, meet at a chess tournament in London. They don't know it, but they are about to compete in the deadliest game ever played.

Shadowing them is Greta, a ruthless resistance fighter who grew up the hard way in the forests of Lithuania, but who is now hunting down some of the most dangerous men in the world.

Men who are also on the radar of Vassily, perhaps the Soviet Union's greatest spymaster. A man of cunning and influence, Vassily was Yulia's minder during her visit to the West, but even he could not foresee the consequences of her meeting Michael.

When the world is accelerating towards an inevitable and catastrophic conflict, what can just four people do to prevent it?

Epic in scope, The Partisan is a thrill ride like no other, taking you from the hallowed halls of Cambridge to the grimy depths of the Moscow underworld, from 1960s London to the Eastern Front in the Second World War.

It's 1951 and the servants of Stalin are closing in on the occupied nations of eastern Europe. As the Red Army tightens the net, Greta - best and bravest of freedom fighters - is told to escape to the West and undertake a dangerous mission.

Greta's task is to find a missing girl: the precious daughter of a partisan general who was sent into exile in the final days of the war.

But the so-called Free World is no place for vulnerable young refugees. Europe is in ruins, the old Empires are dying, and a spectacular cast of spivs, gangsters and rival intelligence agencies are fighting over the scraps.

Crossing the Iron Curtain will require nerves of steel as Greta faces down the French mob, ex-Nazis, Soviet spies, all the glamour and temptation of Paris and ultimately, her own demons.

The Exile is the stunning prequel to The Partisan, Patrick Worrall's critically-acclaimed debut, which introduced the world to the force of nature that is Greta. This is her white-knuckle ride into the black heart of postwar Europe - a terrifying world in which allies and enemies are impossible to tell apart.
