night, all right, all right! To-day's Saturday—and the safety deposit vaults aren't open on Sunday. Mrs. Hayden-Bond's been away all week visiting, but she comes back to-morrow, and there's some swell society fuss fixed for to-morrow night, and she wants her necklace to make a splurge, so she writes Mr. H-hyphen-B, and out it comes from the safety deposit vault, and into the library safe. The old man isn't long on social stunts, and he's got pretty well set in his habits; one of those must-have-nine-hours'-sleep bugs, and he's always in bed by ten—when his wife'll let him. She being away to-night, the boys were able to get to work early. They ought to be able to crack that box without making any noise about it in an hour and a half at the outside." He pulled out his watch—and whistled low under his breath. "It's a quarter after eleven now," he said hurriedly, and moved abruptly toward the door. "I can't stick around here any longer. I've got to be on deck where they can slip me the 'white ones,' and then there's Skeeny waiting for the word to bump off the Sparrow." He jerked his hand suddenly toward the jewels in her lap. "Salt those away before any more adventurers blow in!" he said, half sharply, half jocularly. "And don't let the White Moll slip you—at any cost. Remember! She's bound to come to you again. Play her—and send out the call. You understand, don't you? There's never been a yip out of the police. Our methods are too good for that. Look at the Sparrow to-night. Where there's no chance taken of suspicion going anywhere except where we lead it, there's no chance of any trouble—for us! But this cursed she-fiend's another story. We're not planting plum trees for her to pick any more of the fruit. Understand?"
She answered him mechanically.
