I have a liking for Frank Gardners M16 fiction books but the latest Invasion has baffled me. The story primarily surrounds a MI6 agent going missing in China and two MI6 officers being sent to find her. Meanwhile in London the Chinese secret service have hacked the phone of the officers prinicpal contact back at Vauxhall Cross. The two officers then get a message claiming to be from their contact to meet someone, that leads them into the hands of Chinese Triads who have the agent and are wanting to sell her to the highest bidder, which may or may not be the Chinese secret service. The message doesn't seem to make sense other than being a way of tying the story together.
