Destination Unknown is a gripping mystery-thriller that steps outside Christie’s usual detective format and dives into a world of espionage, danger, and international intrigue. When several brilliant scientists disappear without a trace, the world fears a global conspiracy. Hilary Craven—broken, desperate, and with nothing left to lose—is recruited to impersonate one of the missing scientists' wives and uncover the truth. What begins as a risky mission soon leads her into a hidden world ruled by secrecy and power. As Hilary gets closer to the heart of the operation, she must rely on courage, quick thinking, and instinct to survive. Suspenseful, atmospheric, and full of Christie’s trademark twists, Destination Unknown is a thrilling journey into the darker side of ambition.
