Quantum Breach

As Mark McCabe observed the financial market meltdown in the Dealing Room, his nerves tight and on edge, he felt too old for the game. At 45, why the hell was he doing this, putting himself under such stress, and for what? It had been eight years since he left the regiment. Forex trading was a world in which he felt he did not belong. The adrenaline that fed his veins was risk of a different kind.
Then he receives a call from Brian Stowe, a former Special Forces buddy, now MI5 spook. A suspected money-laundering plot linked to a drug cartel was going on in the very bank that he works. Stowe enlists McCabe and his Singaporean assistant, the highly intelligent and very attractive Ying Lee, a 26-year-old trader, to uncover the money trails.
The chase leads to a terrorist cell known to McCabe from his own murky past, and a deadly game of cat-and-mouse across Asia and the Middle East ensues. Along the way, questions are raised and loyalties become suspect. How is the British Government involved? Who is this shadowy MI6 informer, the Rain Angel? Is she with them - or is she against them?
