Sean Dillon is an assassin. He'll work for anyone as long as the money is right. He hasn't seen the inside of a prison cell in twenty years, being able to change his entire personality just by body language. With his Walther, he is THE best. The man with all the money in the world is Michael Aroun, an Arab with friends in very high places. But for British Intelligence, Dillon is a marked man; they plan to send a killer to catch a killer. The killer they identify is Martin Brosnan, who has turned his back on guns and death, until personal loss ignites a passion for revenge.
