Now he reduced his progress to the rhythm of his boots -- he walked across the land until he came to the sea. Everything that impeded him had to be outweighed, even if only by a fraction, by all that drove him on. In one pan of the scales, his wound, thirst, the blister, tiredness, the heat, the aching in his feet and legs, the Stukas, the distance, the Channel; in the other, I'll wait for you, and the memory of when she had said it, which he had come to treat like a sacred site. Also, the fear of capture. His most sensual memories -- their few minutes in the library, the kiss in Whitehall -- was bleached colorless through overuse. He knew by heart certain passages from her letters, he had revisited their tussle with the vase by the fountain, he remembered the warmth from her arm at the dinner when the twins went missing. These memories sustained him, but not so easily. Too often they reminded him of where he was when he last summoned them. They lay on the far side of a great divide in time, as significant as B.C. and A.D. Before prison, before war, before the sight of a corpse became a banality. But these heresies died when he read her last letter. He touched his breast pocket. It was a kind of genuflection. Still there. Here was something new on the scales. That he could be cleared had all the simplicity of love. Merely tasting the possibility reminded him of how much had narrowed and died. His taste for life, no less, all the old ambitions and pleasures. The prospect was of rebirth, a triumphant return.
