Paradoxically, she was appalled by contemplation of her amazing callousness; outlawed, declassée, she was indifferent to her degradation, and alive only to the joy of freedom from the bondage of any certain social status.

Now as she lingered on the corner, people were passing her continually on their way over to the terminal; and one of these presently caught her attention--a man who, carrying a small oxford hand-bag, came up hastily from behind, started to cross the street, drew back barely in time to escape annihilation at the wheels of a flying squadron of taxicabs, and so for a moment waited, in impatient preoccupation with his own concerns, only a foot or two in advance but wholly heedless of the girl.

Sally caught her breath sharply, and her wits seemed to knit together with a sort of mental click; the man was Blue Serge, identified unmistakably to her eyes by the poise of his blue-clad person--the same Blue Serge who owed his life to Sally Manvers!

In another instant the way cleared and the man moved smartly on again, with every indication of one spurred on by an urgent errand--but went no more alone. Now a pertinacious shadow dogged him to the farther sidewalk, into the yawning vestibule of the railway station, on (at a trot) through its stupendous lobbies, even to the platform gates that were rudely slammed in his face by implacable destiny in the guise and livery of a gateman.

At this, pausing a little to one side, Sally watched Blue Serge accost the guardian, argue, protest, exhibit tickets, and finally endeavour to bribe a way past the barrier. But the train was already pulling out; with a shake of his stubborn head the uniformed official moved on; and ruminating on a power of pent profanity, Blue Serge turned and strode back into the waiting-room, passing so near to Sally that their elbows almost touched without his rousing to the least recognition of her existence.

But that in itself was nothing to dismay or check the girl in her purpose, and when Blue Serge a minute later addressed himself to the Pullman bureau she was still his shadow--an all but open eavesdropper upon his communications with the authority of the brass-barred wicket.

"I've just missed the eleven ten for Boston," she heard him explain as he displayed tickets on the marble ledge, "and, of course, I'm out my berth reservation. Can you give me a lower on the midnight express?"

"No," Authority averred with becoming sententiousness.

"An upper, then?"

"Nothing left an the midnight."
