2024, and China is massing troops on its coast across the Strait from Taiwan. This time it looks like they're serious about invasion - an act that would result in war between the People's Republic and the US and its allies, including the UK. But Britain's Secret Intelligence Service has an agent in play: someone close to the top of the Chinese Communist Party and who's ready to pass on vital secrets that could defuse the escalating situation. But as the handover takes place in a Hong Kong back street cafe, the agent's MI6 handler is snatched before she can transmit the data back to London and disappears. There are few clues as to who might be responsible. Is it China's infamous state security agency, the MSS? Or has another, less predictable player entered the game? MI6 field operative Luke Carlton is despatched to track down the missing agent.
