John Veals is the villainous hedge fund manager in Sebastian Faulks’ best-selling credit-crunch novel “A Day In December.” He is a man with no friends, no culture, no interest in anything other than making money. His nefarious machinations lead to the failure of a major British bank, enabling him to make huge profits from his short positions. Other characters in the novel include Gabriel Northwood, a virtuous lawyer, and Roger Malpasse, a retired banker of the old school.
