This book is the penultimate one in the William Warwick series, which culminates with End game, the first book i had read and posted about in this space, from the series. The story begins with a British national, a wealthy and well connected individual at that, who is assigned the task of mediating a defense contract for the British with the Saudi's.

With British and French being the finalists, the responsibility of swaying the result towards Britain lies with that person who reaches out to a shady contact in Riyadh and before he could realize, he is arrested for a murder he didn't commit, but which happened in front of his eyes, as that of the Italian mediator, who gets killed by the son of the Saudi minister. Having been arrested for a crime he didn't commit, he realizes the murky world of politics is not for individuals like him, but for heavy weights who always have higher targets in mind...
