Martin McGregor left school in Glasgow with nothing but a talent for working with computers. He built up a successful business, installing hardware and software for companies and individuals. He was settled in a loving relationship.

But Martin's company steals theirs and their clients' data, all of it: account details, credit card numbers, identities - and sells them on to international cyber-criminals.

Martin never meant this to happen: it was all from circumstances all through his life, starting with a gangster's money which gave him what he thought was his first lucky break.

Now he is trying to get clear, but his attempts attract the attentions of police and gangsters from three countries, and some people die. His partner knows something is going on, and she once told him never to lie to her.

And in New York, FBI agent Mark Grosvenor is on his trail.
