And incontinently, as though he had taken away all her courage, together with that nickel-plated symbol, she started back, almost cringing in a panic of sadly jangled nerves.
Happily for her conceit, once he had disarmed her, Blue Serge transferred his interest exclusively to his late assailant.
Calmly showing the girl his back, he stepped over, poked the pistol's nose significantly into the folds of the ruffian's neck, and with a sharp word of warning slapped smartly his two hips; in consequence of which singular performance he thrust a hand beneath the tail of the fellow's coat and brought away a bull-dog revolver of heavy calibre.
And then he stepped back, smiling, with a sidelong glance of triumph for Sally's benefit--a glance that spent itself on emptiness.
For Sally was no more there; her uninstructed fingers were already fumbling with the fastenings of the front door when Blue Serge discovered her defection.
There was a breathless instant while the combination of knobs, bolts, and locks defied her importunity so obstinately that Sally was tempted to despair.
She dared not look behind her; but momentarily, as she groped, fumbled, and trembled at the front door, she was aware that a man had backed out of the library into the hall and paused there in the gush of light, staring after her.
And when the door suddenly yielded she heard--or fancied that she heard--his voice, its accent peremptory: "Stop!" Or perhaps it was: "Wait!"
She did neither; the door slammed behind her with a crash that threatened its glass; she was at the foot of the front steps before that sound had fairly registered on her consciousness; and her panic-winged heels had carried the young woman well round the corner and into Park Avenue before she appreciated how interesting her tempestuous flight from that rather thoroughly burglarised mansion would be apt to seem to a peg-post policeman. And then she pulled up short, as if reckoning to divert suspicion with a semblance of nonchalance--now that she had escaped.
But a covert glance aside brought prompt reassurance; after all, the gods were not unkind; the policeman was just then busy on the far side of the avenue, hectoring humility into the heart of an unhappy taxicab operator who had, presumably, violated some minor municipal ordinance.
