A director at the global security firm Dark Corporation contacted MI5 wanting to blow the whistle on something very wrong at the company but then is killed en route the meeting. Max Sargent, an experienced corporate official, is offered a chance to fix an 'indiscretion' by going undercover at the company to find what the man was about to reveal. This will see him following a trail from England to India, then Hong Kong, and then to the Caribbean in pursuit of a plot with terrible consequences for the world.
