Damnation - Peter Beck

Dead clients are bad for business, something that Tom Winter, head of security at a private Swiss bank, knows only too well. When a helicopter explosion kills a valuable client and a close colleague, Winter teams up with the mysterious Egyptian businesswoman Fatima Hakim to expose the truth behind their deaths. Together they follow the money trail around the world and back into the Swiss mountains, the NSA watching their every move. As they start closing in on the truth, Winter and Fatima turn from being the hunters to the hunted, finding themselves in a deadly, high-stakes race against the clock.
