A Hidden Enemy: A Tom Kessler Operation - Book 3

By Peter J Charles

When disgraced Russian intelligence officer Dmitri Volkov resurfaces in the UK, MI5's off-the-books unit is forced into a deadly race to stop him. His mission is simple: steal the guidance data for a next-generation missile system-technology that could shift the balance of power in the Middle East and beyond.

Tom Kessler and his small, unconventional MI5 off-the-books team are the only ones standing in his way. Operating from the shadows, they must turn a compromised insider, outmanoeuvre a seasoned Russian illegal, and survive a brutal attack that leaves the team shattered.

But Volkov isn't working alone. Moscow has sent someone far more dangerous-GRU Colonel Viktor Karpin, a man whose presence signals one thing: the Kremlin wants results, and they want them now.

As the Russians close in, the team is forced into a high-risk deception operation that pushes them to their limits. One wrong move, one missed detail, and the fallout won't just be political-it will be catastrophic.

Fast-paced, tightly plotted, and unflinchingly authentic, A Hidden Enemy delivers a gripping blend of espionage, betrayal, and modern geopolitics.

Perfect for fans of Stephen Leather, Mark Greaney, Mick Herron, Henry Porter and Daniel Silva.
