Two men who hate each other are committed to working together on a job far more dangerous than they knew when they signed up. These men are surveillance experts, lying in a mosquito-infested Iranian marsh for days, part of a huge international operation designed to kill a celebrated maker of the roadside bombs which kill so many British soldiers. And if things to wrong, as far as Her Majesty's Government is concerned, their part in the plot is totally deniable. Gerald Seymour expertly explores the moral compromises of the secret world upon which we rely for our everyday security - and the amazing reserves of courage which ordinary people can find in extraordinary circumstances.
