The hunting season

From the moment playwright Anthony Moore witnesses the murder on a Channel-crossing ferry from France, he becomes a major player in someone else's script. His life is not his own. Instead the role assigned is a dangerous one, involving almost certain death as he confronts a youthful band of terrorists and kidnappers, directed by a shadowy and well-connected figure who stands to make a vast profit one Moore is out of the way... The above is from the jacket description. Moore tries to get away from the intrigue by taking a job in Canada, only to find it follows him. He doesn't know who to trust or why an apparent spy network and criminal enterprise are determined to involve him.
