It should have been the greatest day of David's life. A trip to New York, wife by his side, to visit his new publisher. Finally, after years of lonely struggle it looks as though the gods of fate are on his side. But on the way back to Penn station, a chance encounter changes all of that. David bumps into a man who covertly follows him and, just before he boards the train, passes by him close enough to whisper: 'Remember me.'

When the stranger turns up in his home town, David begins to understand that this man wants something from him...something very personal that he may have no choice but to surrender.

Meanwhile, back in New York, ex-lawyer John Henderson does his girlfriend Kristina a favour and agrees to talk to Catherine Warren, an acquaintance of hers who believes she's being stalked by an ex-lover. But soon John realises that Catherine's problem is far more complex and terrifying than he could ever have imagined...

There are people out there in the shadows, watching, waiting. They are the forgotten. And they're about to turn.
