For the first time the girl became vaguely conscious of, the possibility of an affection, a tie superseding all others; she began to see how it was possible to give herself to this man, not from an impulse of gratitude or because she liked him better than any one else, but because of a feeling, new, mysterious, which gave him a sort of divine right in her.  Something in the expression of his eyes had been more potent than his words; something subtle, swift as an electric spark had passed from him to her, awakening a faint, strange tumult in the heart she thought so utterly crushed.  A few moments before, she could have promised resolutely to be his wife; she could have permitted his embrace with unresponsive apathy.  Now she felt a sudden shyness.  A faint color stole into her pale face, and she longed to be alone.

He readily obtained permission to attempt the capture of the escaped prisoner, Bute; but the murderer had disappeared, leaving no clew.  Brandt learned that the slums of large cities and several mining camps had been searched in vain, also that the trains running east had been carefully watched.  We need not try to follow his processes of thought, nor seek to learn how he soon came to the conclusion that his man was at some distant mining station working under an assumed name.  By a kind of instinct his mind kept reverting to one of these stations with increasing frequency.  It was not so remote in respect to
