At home in Washington, I pull books off the shelves, out of the book towers on the floor, off the stacks of volumes on tables. Inside the back covers are notes written in his hand that he took for reviews and for himself. Piles of his papers and notes lie on surfaces all around the apartment, some of which were taken from his suitcase that I brought back from Houston. At any time I can peruse our library or his notes and rediscover and recover him. When I do, I hear him, and he has the last word. Time after time, Christopher has the last word.
