A Hidden Enemy

A covert British team. A ruthless Russian operation. A single mistake that could ignite a global crisis. 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. A 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.
