The Black Art of Killing by Matthew Hall (Hardback)

"Major Leo Black was once one of the SAS's most fearsome and effective warriors and after twenty years of war, is now striving to be a force for peace. A junior tutor without tenure at Oxford University, his lectures on the ethics of conflict are an inspiration to his students but a threat to colleagues wary of admitting him to their gilded circle. When his oldest friend and comrade is brutally murdered as a part of a dark international conspiracy, Black's new-found principles are put to the ultimate test. There's a violent job to be done and he's the man called upon to do it - the unrivalled expert in the art of killing."--Publisher description
