There was nothing I could say to that. I had the insignia in my inner breast pocket, and I knew that there were few obstacles it couldn't blast away on Earth or on Mars, if I kept remembering what it symbolized with Joan at my side. I went out into the cool night again, past that long tremendous building with just one of its floors ablaze, past the big sky ships looming like sentinel ghosts on their launching pads, past winking lights and speeding cars and pedestrians walking slowly and something inside of me made me feel I'd undergone a kind of sea change, and could face whatever the future might hold without grabbing for a life-line that didn't exist. It was a good way to feel. A man had to sink or swim without having a life-line thrown to him--if he hoped to live long enough to change things around in an important way on Mars. He had to keep his head and breast the raging currents with the sturdiest kind of overhand strokes, or be drawn down into the undertow and battered senseless against the rocks that lined the shoreline. The change must have shown a little on the surface, in the set of my jaw or just the way I was walking, because no less than three pedestrians turned to stare at me as I went striding past them on my way to the New Chicago Underground. I was almost at the northern entrance of the big, tree-lined square directly opposite the Administration Building when it hit me--the memory-recall, the swift emergence from its cubby-hole deep in my mind of the narrow brush I'd had with Death and hadn't even discussed with Trilling. It had been a mistake not to discuss it, because it concerned the Board as much as it did me. Someone who knew about the insignia--or had made a shrewd guess as to just how big a job was awaiting me on Mars--had wanted me dead. The attempt on my life took on a much larger, more crucial dimension when viewed in that light. There were three hundred million people in the United States, and if I'd been just a private citizen, with no more than my own safety at stake, I could have lost myself in that immense ocean of humanity for a week or a month and gained a brief respite. There are plenty of ways you can protect yourself against a surprise attempt on your life, if you have the time to take safety precautions. When there's a would-be assassin at large who is dead set on measuring you for a coffin you have to work the problem out carefully, with a minimum of risk. It takes skill and psychological insight, but it can be done. You've just got to remember that an assassin is never quite normal. Even when a socio-political motivation is the governing passion of his life you're one jump ahead of him the instant you've figured out exactly how his mind works. In fact, one of those safety precautions could have been protecting me as I crossed the square, if I hadn't let my stubborn pride stand in the way. Why hadn't I asked Trilling to provide me with armed protection?
