An Instinct for the Kill (ISBN 0-7322-5891-X) is the second of Antonella Gambotto-Burke's books and her second anthology. It was dedicated to investment banker Mark Burrows. In his introduction to the book, Edward de Bono writes: "Antonella is not afraid of words, ideas, her own opinions or the opinions of others. Perception is personal so truth is also personal. This is much more like Protagoras than like Plato. For Protagoras, perception was the only truth – but it was changeable.
