Tom Wood - The Killer; Victor the Assassin Series, Book 1

Meet Victor.
He’s an assassin—a man with no past and no surname. He lives alone. He operates alone. He’s given a job; he takes out the target; he gets paid. He’s THE KILLER.
Victor in Paris to perform a standard kill and collect for an anonymous client. He completes it with trademark efficiency—only to find himself in the middle of an ambush and fighting for his life. Pursued by determined enemies, a woman too beautiful to be safe, and intelligence agencies from both sides of the Atlantic, Victor will soon discover there is no where left for him to hide…and no one he can trust. But he is every bit as ruthless as those hunting him. And Victor will find out who wants him dead and why—one corpse at a time…
