The Black Dolphin

One prison, one agent, one ultimate test of determination.

Trapped in the depths of Russia’s most impenetrable fortress, Alex, a captured MI6 agent, clings to hope amidst the despair of his forgotten existence. As the clock ticks down on his survival, MI6 races against time to uncover his location and mount a daring rescue mission.

But he’s an inmate who doesn’t officially exist. And no one’s ever escaped the Black Dolphin.

With the threat of discovery looming, will they reach him before it’s too late?

Can they succeed in rescuing him, or will the Russian President’s wrath seal his fate forever?
