Excerpt: 'Some say scientists should keep their noses out of politics. Benson says it's to prevent damage to their olfactory senses. Benson's a physicist. I've known Allan Benson for a long time. In fact I've bodyguarded him for years and think I understand him better than he does himself. And when he shook security at White Sands, my boss didn't hesitate to tell me that knowing Benson as I do I certainly shouldn't have let him skip off. Or crisp words to that effect.
