    “A novelist is, like all mortals, more fully at home on the surface of the present than in the ooze of the past.”
    —Vladimir Nabokov (1899–1977)

    “He maintained that the case was lost or won by the time the final juror had been sworn in; his summation was set in his mind before the first witness was called. It was all in the orchestration, he claimed: in knowing how and where to pitch each and every particular argument; who to intimidate; who to trust, who to flatter and court; who to challenge; when to underplay and exactly when to let out all the stops.”
    —Dorothy Uhnak (b. 1933)
