The best revenge

In China, a colonel in the People's Liberation Army stakes his career, and his life, on a GPS-free missile guidance system that will change the balance of power on the battlefield. In Bath a young Chinese woman has secured the affections of a young brainiac working on that very problem. In Leamington Spa a deep cover operative has given himself away. And in London Jonas Merrick watches all, assessing, planning. A moment, perhaps, for him to strike a blow to China's espionage network in the UK. One thing he does not see, however, is in Moscow. An order given: 'bring me his head'.
