Майкл Ридпат - The Predator

Ruthless, selfish, dangerous. In fact, just right for the job.
At top investment bank Bloomfield Weiss, they taught them to be winners, predators, killer deal-makers. While on the bank’s training programme in New York, Chris and Lenka had become part of a close-knit gang of ambitious trainees, working and playing hard. But when a failed affair sparked a confrontation during a drunken boat-trip, one of the gang died, leaving the rest to cover up the truth of the tragedy.
Ten years later a helpless Chris watches Lenka’s lifeblood soak into the snow of a Prague street — and his world falls apart. With his friend and business partner dead, Chris not only has to fight to keep his company afloat in the face of nervous investors, but must also discover who is behind Lenka’s seemingly random — but coolly professional — murder. Then others are killed, and it looks like Chris could be next.
Now it seems that their shared past might contain an even more sinister secret than Chris had thought. And that someone from the training programme took their lessons rather too seriously. And they won’t let anyone stand in their way...
