On a one-shot gamble of this kind, the 'laws' of chance are no good at all. For that matter, the random tables is full of holes—and that a man with a feeling for the essence of a gamble can make a monkey out of chance almost at will. "And if there ever was such a man, Braun is it.

"For all we know now, evacuating the city may be just what the enemy wants us for some other reason, any one of fifty possible reasons." "Are you trying to say that CIA "You can't take such a gamble," he said grimly. "There are eight and a half million lives riding on it. I can't let you do it." "Actually, you see, your hunch was The expression on Braun's face known Braun, briefly and to no profit to either of us.

In those days, Braun had been the business manager of an insurance firm, the sole visible function of which had put in. "You'll remember we had a deadline on the test, Mr. Braun. Obviously, in a real drop we wouldn't For some reason, he had been amused by the brash youngster who'd barged and its individual dock-wallopers. Braun was in the city over the week end. It would never have occurred to me that he still interested himself in the waterfront, for he'd gone respectable with a vengeance. He was still a professional gambler, and according to what he had told the Congressional Investigating Committee last year, took in thirty to fifty thousand dollars a year at it, but his gambles were no longer concentrated on horses, the numbers, or shady insurance deals.

Joan had been following his career, too, not because she had ever met him, but because for her he was a type study in the evolution of what she called "the extra-legal ego."

"There's always an almost-open conflict and the desire to be accepted your ordinary criminal is a moral imbecile, but people like Braun are damned with a conscience, and sooner or later they crack trying to appease it." between the desire to be powerful he's backing Broadway plays, sponsoring beginning actresses, joining playwrights' groups—he's the only the curtain."
