In the secretive inner circle of the ultra-rich, Alex Hoffmann is a legend.

He has developed an algorithm for playing the financial markets that generates billions of pounds - and feeds on panic.

When one day his system is threatened by a terrifying intruder who breaches the elaborate security of his lakeside home, his life becomes a waking nightmare of violence and paranoia.

But who is trying to destroy him? And is it already too late?
