T.W. Ellis is a pseudonym for Tom Wood, a full-time writer born in Burton-on-Trent who now lives in London. After a stint as freelance editor and film-maker, he completed his first novel, The Hunter, which was an instant bestseller and introduced readers to the antihero assassin Victor. The Victor novels have sold more than half-a-million copies, and Better Off Dead was a BBC Radio 2 Book Club pick. A Knock at the Door is his first psychological thriller.
