“Very sorry, sir, but you know we told you when you opened the account that you must keep your margins up,” Breen had said to an old man. The old man knew; had known it all night as he lay awake, afraid to tell his wife of the sword hanging above their heads. Knew it, too, when without her knowledge he had taken the last dollar of the little nest-egg to make good the deficit owed Breen & Co. over and above his margins, together with some other things “not negotiable”--not our kind of collateral but “stuff” that could “lie in the safe until he could make some other arrangement,” the cashier had said with the firm's consent. Queer safe, that of Breen & Co., and queer things went into it. Most of them were still there. Jack thought some jeweller had sent part of his stock down for safe-keeping when he first came across a tiny drawer of which Breen alone kept the key. Each object could tell a story: a pair of diamond ear-rings surely could, and so could four pearls on a gold chain, and perhaps, too, a certain small watch, the case set with jewels. One of these days they may be redeemed, or they may not, depending upon whether the owners can scrape money enough together to pay the balances owed in cash. But the four pearls on the gold chain are likely to remain there--that poor fellow went overboard one morning off Nantucket Light, and his secret went with him. During the six months Jack had stood at his desk new faces had filled the chairs--the talk had varied; though he felt only the weary monotony of it all. Sometimes there had been hours of tense excitement, when even his uncle had stood by the ticker, and when every bankable security in the box had been overhauled and sent post-haste to the bank or trust company. Jack, followed by the porter with a self-cocking revolver in his outside pocket, had more than once carried the securities himself, returning to the office on the run with a small scrap of paper good for half a million or so tucked away in his inside pocket. Then the old monotony had returned with its dull routine and so had the chatter and talk. “Buy me a hundred.” “Yes, let 'em go.” “No, I don't want to risk it.” “What's my balance?” “Thought you'd get another eighth for that stock.” “Sold at that figure, anyhow,” etc.
