There’s a scene in the 2011 film Moneyball where Brad Pitt’s Billy Beane is mentoring young Peter Brand (Jonah Hill) on how to cut a professional baseball player from the roster: bluntly, without euphemism. 'Would you rather,' he asks, 'get one shot in the head or five in the chest and bleed to death?' Imagine, if you will, that this was not a rhetorical question or an analogy about firing someone but rather a serious, literal question. Now imagine 206 pages of this, and you have a sense of what it’s like to read Malcolm Gladwell’s new book. The Bomber Mafia: A Dream, a Temptation, and the Longest Night of the Second World War is a nasty, brutish book—if it’s also short, it’s not nearly short enough. It is a breathless and narratively riveting story.
