SECURITY RISK At moments like this, General David Walker always thought fleetingly of the good old days when he had hated the army. As usual, he smashed the thought out of his mind with a distinct sense of remorse. He looked up again at the seamed face of the Chief of Staff, General Marcus Meriwether. "This could be serious," he said slowly, with a sick sense of the statement's inadequacy. An old tic suddenly returned, tugging at the left corner of his mouth. The deadly, unsmiling expression on Meriwether's face did not change as he slid more tightly into his chair.

Walker rubbed at the tic. "Nothing," he said quietly. Meriwether leaned forward, his hands crooked backward against the chair arms like catapult springs. "That answer is unacceptable. There are other questions you must answer, Walker, questions in some ways even more
